You helped me in chemistry, math, and now Physics. I can't believe you have been saving my grades all this time dude.
idk🤣🤣
Relatable
Indeed you are really helping
Mine too bro
Well I'm 11 years old, so I'm just learning :)
I am going into my junior year of undergrad before I apply to med school, and because of covid I am taking organic chemistry and physics online. There isn't even a physics lecture. We are only given the textbook as a resource, and then assigned problems that go way beyond the depth of the textbook. You are essentially my physics professor for the semester. Thank you.
Same here.
Good luck becoming a doctor! How’s you’re journey so far
It's been 4 years, how's everything going now?
I swear that when I watched your video I understood the lesson more than my real teacher,continue your are the best
AR. ALNAQBI I hate Kahn academy it really sucks with the explanations on how to do certain things. This guy really knows how to teach people what is going on with good explanations questions and equations.
Actually me too
So true
Same
I feel like watching a video of your own volition means you want to learn from the context of being in a relaxing place like your bedroom, unlike when you're at school and you're obligated to learn, making wanting to learn not of your choice, it also helps that you can just rewind the video on parts you don't understand, rather than waiting for a teacher to help you
Absolutely astonishing video this has fought me so much in so little time. In 19 minutes you taught me what my teacher spent 4 classes on teaching us without anyone understanding what she is saying. This MAN IS LITERALLY THE GOAT 🐐 🐐 🐐. Like you have been saving me in chemistry and now physics for the LAST 2 YEARS. I truly am very grateful to have come across one of your UA-cam videos in grade 10. I really APPRECIATE YOUR EXISTENCE.
You deserve the whole world for helping us in these hard unbearable lessons.
I’m currently doing my A-levels which I need to get into an international scholarship..and your videos are really helping me..thanks Mark,you’re a gift from heaven 🌟
is it a must to take A-levels to apply for an international scholarship? im not taking A-levels but im thinking of applying for an international scholarship so im curious.
@@shissou28 well if you wish to study anywhere in Europe then it’s a must to a certain degree because it gives advantage over students competing with you who only did GCSE’s..but if it’s in the US for example then it is not a must.
more like gift from space
And thank YOU for your opinion, Mr npc
Can i ask what scholarship program is it? I've been looking can't find any
I trust your videos a lot. You're the only one that can make me stay and listen without the interruption of other social media sites ^_^
I don't even bother studying for physics from my textbook anymore. I just watch what this guy does then I do it in the test and I'm killing it so far.
You just saved my ass on a physics problem. Thanks Mark Wahlberg, you are the greatest.
haahhahaha
uhh... this is a very bad word you Know that right
@@power_medoopro7617 I will make sure to never use the word 'Thanks' ever again. My mistake. I forgot we lived in a bubble wrapped society.
lmfao wtf
@@power_medoopro7617 there's not a single 'this' word in their comment wth
You explained it more clearly than my teacher. Thank you very much!
The fact that he teaches so much in a relatively short time is what makes him different from other tutors
And now I understand that force of gravitation equation, thanks for covering these with multiple examples as always! 😊
Just an interior designer curious about astronomy and beyond. Currently ready a book by Brian Cox and came across gravitation force equation and couldn’t wrap my head around it, but thanks to you I can stop reading the paragraph over and over again to understand 😅
Hey JG, I’m sure you already know this from similar comments ubiqutous here, but we really appreciate this, especially it being free of charge. While I cannot make a donation now, my hope is to in the future, keep it up
seriously, how can you cover math, chem and physic? You are so awesomeeee oh my goddd
Really nice examples, and how you explained was really understandable. You explained it good with the drawings and the equations too. Really nice.
I don't really know why it seem effortless in this video than in class. Sir I wish all teachers are like u❤❤
It's the last 4 hours before my physics exams and this is the first time I'm understanding this ish. Thank you kind sir
Few weeks ago, I came across your channel, watched your videos and now I feel I can solve anything !!!!
You saved me on chemistry, now your saving me on physics !!! U da best!!!!
:) amazing teaching skills, easy to follow, makes me more passionate about what it is I'm doing, and Davinci level artwork accompanying it all? 10/10! :-D
the best teacher of all time
Idk what I could've done without your channel
Thank you so much for taking the time to put this video together. It was very well illustrated, and you made it very easy to understand.
I swear this guy is always coming in clutch for me👌
Your the best tutor in the whole universe!
^_^
thank you so much for these videos. you are the reason i'm passing physics
Watching all da way from South Africa 🇿🇦🇿🇦🇿🇦🇿🇦❤ who else is watching from here❤
Me 💯
0:00 1. Calculate the force of gravity between two people.
2:31 2. Calculate the force of gravity between a block and the Earth.
4:56 3. What force of gravity is exerted by the sun on the Earth?
Thanks so much for this video! You explain it so much better than my instructor!
Do you think In the future you could talk a little more about the concepts?
Yea maybe or no
I am very interested in the inner Spins inside a Hadron.Some counterclockwise spins must be responsible for gravitational field of Hadron. Beside the Mass of Hadron itself is due to Higgs Boson Field.
Different Pertinent Density of Lagrangian were written.( to include minimal coupling).
Well if a satisfactory Density of Lagrangian is written then Euler-Lagrange equations will describe
combined Fields.
OH MY GOD BRO I WAS SO CONSFUSED IN PHYSICS CLASS THIS MAN MADE IT WAY EASIER THAN I THOUGHT
I often forget why I like physics your videos always remember me why
Watching this for my physics final tomorrow thank you so much.
Don't know what I would do without you and your lessons,thank you and God bless ❤
This was really great. Thanks for making this video. I still don’t understand why you would do fe-fs to figure out net force though! How do you know it shouldn’t be fs-fe? Is it because sun is farther away?
because the earth was on the right and east is always positive if the diagram was different it would just be the opposite and still give the same answer
Whoa all these examples made understand it a Whole lot better. Thanks a lot
I love hearing the clicking of the calculator in the background haha
We should be paying our tuition fees to you sir not the institutions we go to
Thank you for making this video that is very helpful for the community with useful information👍💯❤
You are the best
this man is carrying me thru ap physics
I just love your teaching methods it's really helped me a lot, big thanks to you❤❤
Very informative Sir!! Thank you for this fruitful knowledge
Honestly such a great warmup thank you!
I appreciate your Teaching you are best but instead of Use calculator you can calculate on board
May be It will helpful for Your Student From India 🇮🇳( IN INDIA IN NEET AND JEE EXAMS WE CANNOT USE CALCULATOR AND FOR 200 QUESTION WE HAVE ONLY 200 MINUTES)
Thank you for making this so easy to understand!!
Thanks so much. I really appreciate it 🙏😩I've understood it perfectly 🥺
I can have a good learning with this. Thanks organic chem.
THANKS SO MUCH THIS IS AMAZING, I NEEDED A VIDEO OR ARTICLE SO MUCH! THANK YOU SO MUCH FOR THIS VID. LIKED AND SUBBED
I love ur voiceeeeeeee~
YOU’RE A LIFESAVER!!!
here coz it's our exam tom thanks bud!
Way better than my professor.
For 15:14 if you just switched the places of the sun and the earth can't you get a positive force too? Like depending on the order everything is placed?
Thank you for saving my test grade
This helped much better and explained
ON THE NECESSARY, TRUE, AND ABSOLUTE PHYSICAL ESSENTIALITY (IN AND WITH TIME) OF THE FACT THAT E=MC2 IS CLEARLY F=MA:
Consider the EXPERIENCE of THE MAN (then involving WHAT IS THE EYE) who is suddenly exposed in what is outer "space" in BALANCED RELATION to the clear fact that E=mc2 IS F=ma (INCLUDING WHAT THEN CONSTITUTES the EXPERIENCE of both the Sun AND WHAT ARE THE POINTS IN THE NIGHT SKY). This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE, AS E=MC2 IS F=MA; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. (Very importantly, outer "space" involves full inertia; AND it is fully invisible AND black.) SO, the Earth constitutes the FULL DISTANCE in/of SPACE in BALANCED and UNIVERSAL relation to what is the MIDDLE DISTANCE in/of SPACE; AS E=MC2 IS F=ma, AS ELECTROMAGNETISM/ENERGY IS GRAVITY !!! INSTANTANEITY is thus FUNDAMENTAL to what is the FULL and proper UNDERSTANDING of physics/physical experience, AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. INDEED, TIME is NECESSARILY possible/potential AND actual IN BALANCE; AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. NOW, consider WHAT IS THE EYE. E=MC2 IS F=MA. Gravity is ELECTROMAGNETISM/energy. (The stars AND PLANETS are POINTS in the night sky.) BALANCE AND completeness go hand in hand. Consider what is outer "space". NOW, consider WHAT necessarily constitutes what is the Sun. E=MC2 IS F=ma. NOW, it ALL CLEARLY makes perfect sense. Think INSTANTANEITY ! TIME DILATION ULTIMATELY proves (ON BALANCE) that ELECTROMAGNETISM/ENERGY IS GRAVITY, AS E=MC2 IS F=MA. OVERLAY what is THE EYE in BALANCED RELATION to/WITH what is the Earth. The sky is blue, AND WHAT IS THE EARTH is ALSO BLUE. Gravity IS ELECTROMAGNETISM/energy. Again, the stars AND PLANETS are POINTS in the night sky; AND THEN very carefully consider what is the EXPERIENCE of what is the Sun. E=MC2 IS CLEARLY F=MA. Think about THE EYE !!! Great. NOW, also consider what is the EARTH/ground in BALANCED RELATION to/with WHAT IS THE EYElid. LOOK around. Think INSTANTANEITY !!! ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/energy. E=MC2 IS F=MA !!! It ALL CLEARLY does make perfect sense. Indeed, BALANCE AND completeness go hand in hand. Beautiful. The INTEGRATED EXTENSIVENESS of THOUGHT (AND description) is improved in the truly superior mind. THOUGHTS ARE INVISIBLE. It is a very great truth that the ability of thought to DESCRIBE OR reconfigure sensory experience is ULTIMATELY dependent upon the extent to which THOUGHT is similar to sensory experience. Dream experience is/involves true/real QUANTUM GRAVITY. In dreams, BODILY/VISUAL EXPERIENCE is invisible AND VISIBLE IN BALANCE !!! The EARTH AND THE SUN are E=MC2 AND F=ma IN BALANCE. There is no outsmarting the genius of dreams. Importantly, dream experience GROWS/increases. In dreams, it is you AND other than you are IN BALANCE. GREAT. SO, you don't see any people on what is THEN the BLUE EARTH. Think !!! Gravity IS ELECTROMAGNETISM/energy. ELECTROMAGNETISM/ENERGY IS GRAVITY. E=MC2 IS F=MA !!! Think very carefully about the experience of THE MAN who is standing on what is the EARTH/ground. Magnificent !!!

THE CLEAR AND UNIVERSAL MATHEMATICAL PROOF THAT E=MC2 IS F=MA:
Gravity IS ELECTROMAGNETISM/energy, AS E=MC2 IS F=MA. The Earth (A PLANET) is a MIDDLE DISTANCE form that is in BALANCED relation to the Sun AND the speed of light (c), AS the stars AND PLANETS are POINTS in the night sky; AS E=mc2 IS F=ma. ACCORDINGLY, gravity AND ELECTROMAGNETISM/energy are linked AND BALANCED opposites; AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. E=mc2 IS F=ma. This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE. Very importantly, outer "space" involves full inertia; AND it is fully invisible AND black. SO, the Earth constitutes the FULL DISTANCE in/of SPACE in BALANCED and UNIVERSAL relation to what is the MIDDLE DISTANCE in/of SPACE; AS E=MC2 IS F=ma, AS ELECTROMAGNETISM/ENERGY IS GRAVITY !!! INSTANTANEITY is thus FUNDAMENTAL to what is the FULL and proper UNDERSTANDING of physics/physical experience, AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. INDEED, TIME is NECESSARILY possible/potential AND actual IN BALANCE; AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. SO, time DILATION ULTIMATELY proves (ON BALANCE) that ELECTROMAGNETISM/ENERGY IS GRAVITY; AS E=MC2 IS F=MA !!! GREAT !!! BALANCE and completeness go hand in hand. Indeed, it ALL CLEARLY makes perfect sense.
Gravity IS ELECTROMAGNETISM/ENERGY. A PHOTON may be placed at the center of what is THE SUN (as A POINT, of course), AS the reduction of SPACE is offset by (or BALANCED with) the speed of light; AS ELECTROMAGNETISM/ENERGY IS GRAVITY; AS E=MC2 IS F=MA. (The stars AND PLANETS are POINTS in the night sky.) "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. Indeed, gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE; AS ELECTROMAGNETISM/ENERGY IS GRAVITY; AS E=mc2 IS F=ma. Accordingly, the rotation of the Moon MATCHES it's revolution. GRAVITATIONAL force/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY; AS E=mc2 IS F=ma. Gravity IS ELECTROMAGNETISM/energy. This NECESSARILY represents, INVOLVES, AND describes what is possible/potential AND actual IN BALANCE. Gravity AND ELECTROMAGNETISM/energy are linked AND BALANCED opposites, AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY !!!
By Frank DiMeglio
WHY ELECTROMAGNETISM/ENERGY IS UNIFIED AND BALANCED WITH/AS WHAT IS GRAVITY:
Gravity AND ELECTROMAGNETISM/ENERGY are LINKED AND BALANCED opposites, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Therefore, Einstein's equations and Maxwell's equations are unified (given the addition of a fourth spatial dimension); AS E=mc2 is DIRECTLY and fundamentally derived from F=ma; AS TIME DILATION proves that electromagnetism/ENERGY IS GRAVITY. ACCORDINGLY, Einstein's equations predict that SPACE is expanding OR contracting in and with TIME; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. GREAT !!! (Very importantly, outer "space" involves full inertia; AND it is fully invisible AND black.)
Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Accordingly, the rotation of the Moon MATCHES it's revolution. "Mass"/ENERGY involves BALANCED inertia/INERTIAL RESISTANCE consistent WITH/as what is BALANCED electromagnetic/gravitational force/ENERGY, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Accordingly, objects fall at the SAME RATE (neglecting air resistance, of course); AS ELECTROMAGNETISM/ENERGY IS GRAVITY.
Gravity IS ELECTROMAGNETISM/ENERGY. A PHOTON may be placed at the center of what is THE SUN (as A POINT, of course), AS the reduction of SPACE is offset by (or BALANCED with) the speed of light; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Energy has/involves GRAVITY, AND ENERGY has/involves inertia/INERTIAL RESISTANCE. THE SUN purely exemplifies time DILATION. INSTANTANEITY is FUNDAMENTAL. Time DILATION proves that electromagnetism/ENERGY IS GRAVITY, AS E=mc2 is DIRECTLY and fundamentally derived from F=ma. "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. GREAT !!!
The stars AND PLANETS are POINTS in the night sky. Let's compare this directly with BOTH a falling object AND the speed of light (c). Great. E=mc2 IS F=ma. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. GRAVITATIONAL force/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/ENERGY. This NECESSARILY represents, INVOLVES, AND describes what is possible/potential AND actual IN BALANCE. Time DILATION proves that electromagnetism/ENERGY IS GRAVITY, AS E=mc2 is DIRECTLY and fundamentally derived from F=ma. INSTANTANEITY is FUNDAMENTAL to the FULL and proper understanding of physics/physical experience. Ultimately and truly, TIME is possible/potential AND actual IN BALANCE; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. The ultimate unification of physics/physical experience combines, BALANCES, AND includes opposites, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. GREAT. It ALL makes perfect sense. THINK !!!
The Earth that undergoes time DILATION IS thus represented (ON BALANCE) as what is A POINT in the night sky, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. (So, notice that the BLUE SKY IS no longer visible. Think.) E=mc2 IS F=ma. It is FULLY proven. Gravity IS ELECTROMAGNETISM/ENERGY. ELECTROMAGNETISM/ENERGY IS GRAVITY. Alas, the INTEGRATED EXTENSIVENESS of THOUGHT (AND description) is improved in the truly superior mind. I have truly, CLEARLY, AND MATHEMATICALLY unified physics/physical experience. OVERLAY what is THE EYE in BALANCED RELATION to/WITH what is THE EARTH. (Notice the black space of THE EYE, AND the DOME of a person's eye is ALSO visible.) THE EARTH is ALSO blue. Again, E=mc2 IS F=ma. The stars AND PLANETS are POINTS in the night sky. Time dilation proves that E=mc2 is DIRECTLY and fundamentally derived from F=ma, AS electromagnetism/ENERGY IS GRAVITY. It ALL makes perfect sense. Gravity IS ELECTROMAGNETISM/ENERGY. ELECTROMAGNETISM/ENERGY IS GRAVITY. BALANCE AND completeness go hand in hand.

For the first problem, what is the impact velocity achieved when the two bodies collide (due to gravity alone?)
You are my therapist
What mode/set up in calculator should be used doing this? Mine always ends up syntax errored.
Thanks a lot for the explanation but i still don't know how did you find the Fnet in the last question without having the distance between the moon and the earth and the sun.
When you're calculating the gravitational force between for instance the earth and the sun, shouldn't you also take in account the radius of those two objects, and add it onto the distance between the two? Or does the value of the distance between the two objects already take that into account?
not all heroes wear capes
Really Helpful 👍Thanks alot
You're the life saver 🗣💯🙏
YOU ARE THE BEST
thank you
you are the best i swear
Hi, I have been watching your physics videos and you've helped me a lot. Is there a way to show us exactly what you are putting in the calculator because I've tried and didn't come close to your answer? Perhaps I am doing something wrong. Thank you 😊
Hello, came here to learn more. I have a question.Why must we square the radius?
Pls sir can answer this question for me The gravitational force on a mass of 1kg at the edge surface is 10N.Assuming the earth is a sphere of radius R,calculate the gravitational force on a satellite of 100kg in a circular orbit of radius 2R from the center of the earth.
Here from ms bhatias godlike class 🔥🔥🔥🔥
JG you are amazing keep up the good work nice presentation sir
6:24 the most impressive part is how fast you type all this in a calculator. Can you teach me this magic
Whats the formula if youre finding for the two masses?
Take the constant which never changes over the proportional amount of the equation which is veneer linear over vector43 which is c over gve t v e over 3 e 2uc
amazing work
I never understood this topic better
Hi I still don't get the resting part. (second question) If the earth pulls the block with a force of F, there will be a reaction force acting on the block. Hence its balanced. But since the block also pulls the earth, does it mean the net force acting on the block isn't 0?
I have a correction, is the power of ex. 4 not 29?
Because my calculation says that it is 29 not 9.
R= 5.0 x 10^29m
same
Yeah I got the same thing
Same
You are the best
It's really nice.
Thank you so much. 🎉
When I type this into my calculator it doesn't come out to 1.28x10^-6. Instead I am getting 0.000001281, which i know is what that equals. but how do i get the answer like this one ^........?
I can't be the only one who loves the sound of him pressing the buttons on the calculator 😩
as if we are ever given this many variables
Yes but we already know how to find these variables if ur teacher is at least half decent, this is just the basics. It’s all just an extension of kinematics
Helpful indeed
I really want the step by step explanation since what would happen to the exponent of 10?
How did you calculate?
I want to see the calculation
Other wise 👌
Any one to show the calculation??
When it says times the square root of -11 it means you move the decimal 11 spaces forward and the number would be 0.0000000000667
@@melinacastro3730 thank you
No prob 😁👌
Thank you!
Hello sir, may i ask how to apply this on calculator? Thank you
thank you thank you thank uuuuuuu 🥺🥺
Hello there 👋, I would like to ask what is the unit of the "G"?
Hello could you inform me how you obtained the value for the density of the earth - thanks
Thanks 😊
U re yhe the best
How'd you get the anser in 4:10
Thanks helped a lot
at 7:00 shouldn't we add the radius of the sun and the radius of earth to R?
Thank you so much
i hope you can add problem about x resting in jupiter.still its the best thank you
