Please sir, can you explain the second average speed formula.
The first one was
Xf - Xo/t which made sense
but this second one: S = Xf + Xo/2
is really confusing sir.
Can you please link me a video or the video I tried to go ahead on this problem and failed horribly I just need more examples and example problems with solutions so i can maybe work through them on my own to understand it better because I’m horrible at kinematics and I’ve already made it to 2d motion please
my physics professor botched everything for our Gen Physics course, we're gonna be great friends this semester
You're literally carrying me through my electrical engineering degree right now. THANK YOU!!!!!
Sameee
literally same
Okay
Me with mechanical engineering 😭 thank you so much for real ❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️
Ya'll haven't learned this in high school?
Thank you. I am an online college student and I always come to your channel when I'm struggling with subjects. You always make them so much easier to understand and the way you break things down so simply really helps me feel confident with the material.
He never saw it 😭😭😭
@@karbonkillershorts8551 so sad
same here
@@karbonkillershorts8551he did just that he never responds or likes comments

The fact that this was posted today right when I needed some kinematics review for my MCAT!! Thank you so much, this channel always pulls through.
GOOD LUCK ON THE MCAT!!! im just here for a physics final
Hi Christiana! If you need even more practice, we have made a playlist of hundreds of worked out problems for students like you who want more practice problems! A lot of viewers that use our channel are also studying for the MCAT! Here is the link: ua-cam.com/play/PL_3h4GvKc6GAniH6iyxOqX35ZI-tGEChJ.html Cheers and good luck with studying! 😀
how did it go?
See vedantu jee enthuse they have better videos
You need pass physics in MCAT?
Currently 9 hours until my exam. Ur a life saver as always
Edit: I fucking nailed it thanks
Why have you got exams this time of year? Are you in UK?
@@kadencronick nah I’m in canada, my exam was at 9am and I was watching this at 11:30 pm yesterday
@@isamkarroum8716 me too bro, the weather makes it even more difficult to study, my exam is by 1:30 on Sunday, hope i nail it, wish me luck
@@bzoa430 u got this, I did pre well on mine lol. Lmk how he’s goes
Can anyone here help me confirm the answers for the second question would mean a lot
For self-reference...
Scalars are just the items themselves (magnitude) with no direction or anything (speed, distance) and Vectors are the items with the direction (velocity, displacement).
Velocity is the speed with the direction and is calculated with Displacement/Time while Speed is just the rate at which something moves (no attention to direction, hence why it is not a vector) and is calculated with Distance/Time.
Scalars like speed and distance have no direction, so they are always positive, and vectors like velocity and displacement do have directions, so they can be positive and negative.
You calculate distance by adding up the amounts traveled as their absolute value, regardless of direction. You calculate displacement by comparing the final position with the initial position (no attention to distance but instead to final distance from initial distance) (ex. Sal moves 10 in east, 11 west: The displacement would be -1 because the initial position is assumed to be 0 and after Sal went 10 places east, he returned 11 west, and so ended up 1 place more west than where he started, which was 0, hence since it was going to the left side, the displacement is -1.
Instantaneous (speed) vs average (speed) is that instantaneous is calculated as an absolute value and tells you the speed at an instant in time, while the average speed tells the average over an interval.
Avg. velocity is displacement (final position minus initial position)/time, while Inst. velocity is the change in displacement (final position minus initial position)/over the change in time.
Displacement along the x-axis and y-axis are essentially the same, the only difference is that it is the final position minus initial position in the x and y axis accordingly.
Average velocity is (displacement) change in position (X final- X initial; displacement;)/time, while average acceleration is the change in velocity (v final- v initial)/time.
Thank you
Thanks
THANK YOU FOR THIS!!!
woah... I'm taking physics for summer and I can't believe that this video was posted like a week ago.... what freaking timing.
@@kleasinjari6541 me too.
my exam is in less than 24 hours and I just found this video, I love you man you are a life saver.
mine 24
Minutes lmao
I'm itching to know what you got but...no1 ever responds to that😂
@@kingdribs9286 aced it
@@jaafarmayyah1623 Congrats🙂 can't believe you actually responded😂pretty quickly too
@@kingdribs9286 im studying rn too im just bored
this guy manages to teach this concept better than my physics professor...who has a PhD in Theoretical Physics.
Or does he have a theoretical PhD in physics...
Bless your soul 🙏 for doing this. I've been struggling so bad in physics and you are literally helping me more than my actual professor
Really missed the time when i was learning physics in foundation study. Im currently in first year mechanical engineering study. I really like all your videos. It really help me during my foundation study.
I'm studying this for foundation year study!!!!!!
I'm an Engineering major and I'm being carried by this man.
Thankyou ❤
mannn u saved my maths in high school now my chemistry & physics in college, couldnt thank u enough, n none of my teachers do teaching n explaining better than u do
Brother your teaching made me fall in love with physics.......... THANK YOU :)
ngl I could simp for this man's voice any day 🚶♀️
(2)
i stand by that HAKSGDHD
🤓
👀
just hope ur not a guy bruv
Hey, thank you for these videos. I find that I hate being taught this stuff in class but love when I self-teach myself. Seriously a great video :).
First AP Physics test next Thursday! This helped soooo much
You pass the ap test?
Howd it go
Me too
The fact that this guy has such great example problems is so helpful
this is literally right on time for my finals! literally 13 hours away omg you're a blessing
Good luck
How was it ?
I have final tomorrow 😳
I am good at physical and math and chemistry ☺😚😊
@@IsaacAwad.04 same :(
I have been so intimidated by physics, but you broke it down and made it very simple. thank you
I wish you were my teacher for every single subject.
You are life saver Man ♂️🙂.
This guy know how to explain clearly every each of problems. He don't miss any problem what I confuse. Really useful for us because his explanation is totally understand for all.
This gentleman has gotten me through so many classes
Once my professor told if u don't like physics that means ur teacher is not good 😊 because physics is a whole damn universe creation things and amazing things to learn...
you literally just made kinematics looks so easy. thank you!!!
This has been very helpful,thank you so much and continue with the amazing works. ❣️
Trying to review for my Physics midterm and I learned this stuff months ago so I'm watching this to refresh my memory of the knowledge, thank you man! 💪‼️
I love all your videos. They are not only informative but also easy to understand
it's melting my uninterested brain
Amazing explanation. Just what I needed.
Hi, thanks for your efforts. What program do you use to write on the blackboard? do you write with a mouse or a digital pen? or do you use LCD Pen Display? I teach online and I am having hard time writing with a mouse? thanks
Thanks very much organic chemistry tutor! Hope you notice us, we are so grateful to this channel!
Thank you so much for doing all the work my physics teacher never bothers to
Always thankful for this channel
You just earned another sub😊 I really need this for robotics
This man is a life saver
You’re real help when it comes to AP Physics 😄
OML THANK YOU, MY TEACHER DOESNT KNOW HOW TO TEACH ANYTHING SO THIS IS VERY HELPFUL
Thank you sir. Your videos are always so helpful.
You have helped me get through my bachelors degree in biology this videos are so helpful
we have midterms exam tom, and this helps me a lot to understand. thankyou😭
Man, this video is so good, thanks, you made me understand this better.
you are teaching very good I am 7th class student and I am strolling wit kinematics and you make it very easy to me
I will always follow you
Thank you for sharing your knowledge I'm learning a lot from this channel its so much helpful .
Thanks mate I will ace my physics paper coz of you 👏👏👏
Dude, seriously, thank you.
Thanks! 😢 I have been cramming all day because tomorrow is our exam and watching this video was my lifesaver especially I have trouble remembering things
Wow wow i got everything to understand physics thank you
You always nail that science mate
Never dis kinematics in school but now have I understand it thanks a lot
You are always there to help me
feb 10, 2024. I will survive physics🤞🤞
I hope I make it in physics
Could you do an exact differential equations video please?
Thank you so much for helping out people understand physics thank you and I am studying physics!
Thank you very much for the awesome content. All love from Egypt.
I understand this so much more than in class thank you
Missed those moments. Thanks 👍🏼
please do a video explaining the way you algebraically multiply and divide using fractions. this concept is alien to me
Cramming the night before mid year ...so easy when you have this guy
Your existence is my happiness man thank you
Thank you for sharing your knowledge...i came to this youtube channel because hes better than our instructor ahhaha ..
i hope, i will pass the exam thanks to you
26:35 u can basically multiply 40m/s to 3,6 to get km/h
equals 144 and u can divide it by 1.6,u will get 89 anyway
ur method is a little complicated
Yeah he was doing it the long way lmao.
Great explanation and informative
I have an exam on Saturday , and this video is help me a lot
Thanks man
Really needed this
I want to ask if you can change the units of the miles to metres and hours to second ?
I wish you were my teacher for every subject
I’m so sick of physics
Same I’m taking it as a required high school class and I’m so sick of it, I can’t wait until this year’s over so I don’t have to take it anymore
@@HyunjinsAmericano453what’s bad about it? Im taking it next year along with ap chem
@@charlenenelly6527 It’s just really hard all together. If you’re good at math then you’ll be good at it, bcuz it has a lot to do with equations. But I had a rlly shitty teacher so it was harder for my class.. Physics has a lot to do with momentum, velocity, acceleration, and movement all together. It talks a lot about Newton’s laws and stuff like that
I feel you 😞
I am in grade 9 but I got each and every word he said it's so simple 👍 thanks a lot 👍
Awesome Job! I AM FROM BRAZIL, AND I LEARNING ENGLISH BUT I UNDERSTOOD
Omg ! Where have you been ? I missed you !!
tomorrow is my exam and i found this video, how lucky
Wow amazing explanation
Manifesting a good grade on my first ap physics exam
I feel like his voice makes me wanna know more 😩he makes me wanna love science more💜
How does this man learn all this material before organic chemistry tutor videos are made??
Thank you so much!
Legends sir
THANKS FOR ALL THE BEST VIDEOS
I have a question. 8:04 to calcululate the initial postion I would assume it would be 0 right? And then the final postion I would do 13-4 =9 and then using the formula 9-0=9 . Is this the correct way? Please help me I’m a 9th grader and a little scared about physics 😢
Now I have a hope that I,ll pass tomorrow's exam
The video discusses the differences between scalar and vector quantities, distance and displacement, speed and velocity, and provides formulas for constant speed and constant acceleration. It also demonstrates how to calculate average speed, average velocity, and instantaneous velocity.
Key moments:
00:02 Kinematics describes object motion without force references. Scalar quantities have magnitude only, while vector quantities have magnitude and direction.
-Difference between scalar and vector quantities. Scalar has magnitude only, vector has magnitude and direction.
-Displacement vs. distance. Displacement includes direction, distance is scalar and always positive.
-Temperature as a scalar quantity. It lacks direction and is described only by magnitude.
06:07 Understanding the concepts of distance, displacement, speed, and velocity is crucial in physics. Distance is scalar, always positive, while displacement is a vector with magnitude and direction.
-Difference between distance and displacement. Distance is scalar, while displacement is a vector with magnitude and direction.
-Differentiating speed and velocity. Speed is scalar, while velocity is a vector with magnitude and direction.
12:21 Average speed and average velocity may differ when there are changes in direction during motion. Instantaneous velocity represents the velocity at an instant, while average velocity indicates the average over an interval.
-Difference between average speed and average velocity. Average speed and velocity comparison with changes in direction.
-Understanding instantaneous velocity vs. average velocity. Calculation methods for instantaneous velocity and average velocity.
-Formulas for constant speed and acceleration. Relationship between displacement, velocity, and acceleration in motion calculations.
18:15 Understanding the equations for displacement, velocity, and acceleration is crucial for solving physics problems. Different equations can be derived and applied for motion along the x and y axes.
-Deriving and rearranging equations for displacement, velocity, and acceleration. It's important to have a list of equations for physics problems.
-Applying equations for motion along the x and y axes. Formulas can vary for different directions in physics problem-solving.
-Considerations when dealing with constant speed and acceleration. Use of symbols like v and v bar can vary based on the type of motion being analyzed in physics problems.
24:18 To convert meters per second to miles per hour, you need to convert meters to kilometers, then kilometers to miles, seconds to minutes, and minutes to hours. The final calculation results in 89.5 mph.
-Unit conversion steps involve converting meters to kilometers, kilometers to miles, seconds to minutes, and minutes to hours to calculate speed in mph.
-Detailed explanation on canceling units during conversions and the importance of ensuring units match in calculations.
-Solving for average velocity using the formula for displacement over time, with an example of a bus moving east and then west from a city.

Thank you so much for everything
But the "Constant acceleration" formulas are so many
god bless you for preparing me for next sem
Thank you so much, may God bless you 🙏😇
Bro you have everything
thank you , you are really good
i used to watch this channel before every test, now a year later i am an art student in college, and the moment i heard this guy's voice i had some real ptsd flashbacks lmaooooo
I have a question, will the initial position of any particle in the equation in the video always be "0"
Do i have to pay to get the full video?
Thank you a hundred times
You are super hero. Thank you so much 🌹🌹شكرًا
Yaaahooooo tanx organic chemistry you are ohhhh you are so great man you are father of knowledge tanx
I don't understand why you have you different equasions for (V bar)? Please explain
I am a little confused if the bus moved from 50 miles east to 90 miles west, is it not supposed to move from east to west and not have a negative 90 miles. Can someone please help me?
PERFECT JUST WHAT I NEEDED
really good video
Damn you maaaad smart. U knows everthing! :D Thank you for making this video. Blessed.
Could you send a Link where we could download different documents to practise and study please??😇😇🙏🙏
Why does the average velocity have two formulas first you added then divided, and then you subtracted final minus initial ??
