In this lessons we will discuss the important topics of energy and work in terms of their applications to chemistry and physics. We want to understand when an atom or molecule has electrons in a high energy state and how that compares to a low energy state and what this means. When we say energy, we are usually referring to potential energy, but we also discuss kinetic energy and contrast this with work, which is energy that has been used to move an object. Energy is very important to understand in chemistry because it governs how chemical reactions happen and determines when and how fast the reaction proceeds.

If this had been the lecture on my first day of high school chemistry I would have probably become an engineer instead of a programmer.
OMG, I feel like a genius whenever I watch any video lesson about physics and have full comprehension of it. Thank you sir.
Welcome!
Absolutely enjoying learning from these videos
@@MathAndScience Consider what is E=MC2. c squared CLEARLY (AND NECESSARILY) represents a dimension of SPACE ON BALANCE, AS ELECTROMAGNETISM/energy is CLEARLY (AND NECESSARILY) proven to be gravity (ON/IN BALANCE); AS TIME is NECESSARILY possible/potential AND actual ON/IN BALANCE. Accordingly, ON BALANCE, the rotation of WHAT IS THE MOON matches the revolution. Consider what is THE EARTH/ground. Consider what is E=MC2. Now, consider what is THE EYE; AND consider what is the TRANSLUCENT AND BLUE sky ON BALANCE. SO, consider what is the BALANCED MIDDLE DISTANCE in/of/as SPACE; AS c squared CLEARLY represents a dimension of SPACE ON BALANCE; AS WHAT IS E=MC2 CLEARLY proves (ON BALANCE) that ELECTROMAGNETISM/energy is CLEARLY AND NECESSARILY proven to be gravity (ON/IN BALANCE). Indeed, notice what is the fully illuminated (AND setting/WHITE) MOON ON BALANCE. Now, consider what is the orange (AND setting) Sun ON BALANCE !! They are the SAME SIZE as what is THE EYE. The rotation of WHAT IS THE MOON matches the revolution, AS TIME is NECESSARILY possible/potential AND actual ON/IN BALANCE; AS ELECTROMAGNETISM/energy is CLEARLY AND NECESSARILY proven to be gravity (ON/IN BALANCE) !!! CONSIDER WHAT IS E=MC2 ON BALANCE. Gravity is an interaction that cannot be shielded (or blocked) ON BALANCE !!! Consider TIME AND time dilation ON BALANCE, AS ELECTROMAGNETISM/energy is CLEARLY AND NECESSARILY proven to be gravity (ON/IN BALANCE) !!! The stars AND PLANETS are POINTS in the night sky ON BALANCE !!! c squared CLEARLY represents a dimension of SPACE ON BALANCE, AS ELECTROMAGNETISM/energy is CLEARLY AND NECESSARILY proven to be gravity (ON/IN BALANCE) !!! Indeed, TIME is NECESSARILY possible/potential AND actual ON/IN BALANCE; AS ELECTROMAGNETISM/energy is CLEARLY AND NECESSARILY proven to be gravity (ON/IN BALANCE) !!! Think. What is E=MC2 is dimensionally consistent. What is THE EARTH/ground is fully consistent with/as (AND IT IS BALANCED WITH/AS) what is E=MC2 (ON/IN BALANCE). BALANCE AND completeness go hand in hand. ELECTROMAGNETISM/energy is CLEARLY AND NECESSARILY proven to be gravity (ON/IN BALANCE), AS TIME is NECESSARILY possible/potential AND actual ON/IN BALANCE. c squared CLEARLY represents a dimension of SPACE ON BALANCE. Again, ON BALANCE, consider what is the BALANCED MIDDLE DISTANCE in/of/as SPACE, AS ELECTROMAGNETISM/energy is CLEARLY (AND NECESSARILY) proven to be gravity (ON/IN BALANCE) !!! CLEARLY, I have mathematically proven and explained what is the fourth dimension. Magnificent.

I know the feeling of feeling smart, after watching this genius, versed in so many technical subjects. I have watched him dig into DNA and explained for example the 4 base pairs of DNA, and why Adenine and Guanine always connect together. That was one of my most eye-opening and fee-smart moments I've had while trying to grasp and understand New information.
You are doing immeasurable contribution to science, i wish we could clone you and distribute them to every school as teachers
Yes!! I agree😊
LoL YES
you are the greatest tutoring channel I've ever seen ❤
Like a masterful conductor, you have orchestrated my journey of learning, transforming complex concepts into captivating melodies that resonate with understanding. Your passion for knowledge is contagious, igniting a spark of curiosity that will forever guide my path.
I don't even need to watch, but just listen and I can hear how excited you are about it, that makes for a great teacher! Thank you!
Wow, thank you!
Such a pleasure to listen to a person who has a real gift (desire plus knowledge) for explaining
What makes lessons taught by Math and Science exciting is he links Physics and Chemistry perfectly. This can only be done by people who have best knowledge and understanding in science and nature.
Thank you so much!
Again very well explained. Your talent is that you make everybody understand the topic.
I really appreciate the nice comment!
Thank you so much for all your hard work you put in, It means the world.
I really appreciate your kind words!
Thank you for this video! I started watching you back 2 years ago, and I aced all of my STEM related subjects because of you. Instead of doing it just for the grades, your videos hooked me into science and mathematics even more. Your videos definitely improved my skills. Advanced congratulations to your 1M subscribers!
Wow thanks so much. So happy to hear of your success! And thanks for the 1M kind words! Actually hard to believe it!
I thought that I was just slow to pick up these kinds of concepts since I had to pause the video, and then replay it again as it's hard for me to sink numbers in my mind. Thanks for making this topic digestible for everyone.
This is the type of science that is interesting to me! It's the kind of science we deal with every day but never think about it.
Very true!
One of the best lesson I had. I wish my high school Can be like you. Thanks.
Your work is truly outstanding, Professor. Your expertise in your field is unparalleled, and I am grateful for the knowledge you have shared with us. Thank you for being an inspiration and setting the bar high for all of us striving to make a difference.
thank you i did not realise you can relate energy to both chemistry and physics
Turned this for my 7 y.o, he enjoyed. To my surprise. It was good for me as well, to refresh my school program.
Awesome!
الطاقة الكامنة : وهي الطاقة الغير مستثمرة ومثالها : الشخص الذي لديه طاقة مخزونة تجعله طبيبًا ، مهندسًا ، معماريًا ....
العمل : هو استخدام الطاقة الكامنة ، وهو إنجاز شغل ما ، عبر مسافة .
ملاحظة : يرتبط العمل ارتباطًا وثيقًا بالطاقة الكامنة .
رمز المسافة : d .
رمز القوة : f .
القوة الثابتة : مثل الدفع بقوة ثابتة لا تتغير .
القوة الغير ثابتة : مثل الدفع بقوة غير ثابتة تتغير وستدخل في التكامل والتفاضل لذا لن يأخذها .
رمز الشغل : w .
معادلة الشغل : القوة × المسافة .
او رياضيًّا :
W = F . D
وحدة المسافة : m / المتر .
وحدة القوة : n / نيوتن .
وحدة الشغل : j / الجول .
اما الناتج فسيكون جول بالثانية مثال :
W ( 3 ) = F ( 3 ) . D ( 1 ) => 3 J/S
الطاقة الكامنة مثلًا اذا صعدت عاليًا راح تزداد واذا سقطت صرفتها
للتوضيح :
صندوق
|_| صندوق ٢
|_|
________ _________
ارض ارض ايضًا
الصندوق ٢ لديه طاقة كامنة اقل لذلك لن يكون سقوطه كقوة سقوط صندوق ١ .
القوة الكامنة : الكتلة مضروبة بالجاذبية والارتفاع
PE = mgh
g = m/s²
H = m
M = kg
الطاقة الحركية : الطاقة الكامنة مخزونة مثل سحب الشريط المطاطي اذا تركته تكونت عندك الطاقة الحركية .
KE = 1/2 mv²
الطاقة الحركية = نصف ضعف الكتلة وسرعة الجسم
سرعة الجسم m/s
الكتلة kg
المثال على الطاقة الكامنة والحركية :
لديك مدينة ملاهي فيها افعوانية كالتالي
1
_
2 \ /
_ \ /
\ / \ /
\ / \ /
________\ /___\ /___
اذا كنت على أي ارتفاع سواء ١ او ٢ فانك لديك طاقة كامنة محددة حسب الارتفاع والمسافة والخ ، وإذا نزلت فأنت هنا تستخدم الطاقة الحركية .
اتذكر ان الدكتور قال الجاذبية أقوى بملايين المرات من القوة الكهربائية ؟ هنا ستستفاد من هذه المعلومة .
القوة الجاذبية
F = G ( ثابت الجاذبية ) أس ( m¹m²/r²)
هذا ليس درسًا للفيزياء لذلك ابحث عن ثابت الجاذبية في الفيزياء .
R المسافة بين الاجسام
M = kg كيلوجرام
R = m متر
F = N نيوتن
القوة الكهربائية
F = K ( q¹q²/r²)
Q هو شحنة الجسم
K هو ثابت الكهرباء
R المسافة بين متر الاجسام
Your lessons has helped me to be top 2 in my class
Sir you are the best science and math teacher in the world. I have watched all of your videos.
Wow thank you so much!!!
Thank you.
Good pedagogy makes a real difference!
Awesome approach to the knowledge of energy. Practical.
The continuity of your teaching is so beautiful. Thank you so much. You help me be a better teacher for my students.
You speak rightfully that we should think problems in terms of energy! You are best in business sir!
Thank you,Jason Gibson.
Welcome!
Great class, thank you...
Im really grateful for these lectures. You're so clear and concise with your explanations. Thank you very much. I look forward to watching the whole series.
He is a Godvsent maths and science tutor. He explains more in details based on the previous lessons and. will proceed accordingly to the course direction..
Thank your. Sir. Jason for all your patience ..
I can. remember. .. 32 ft / sec / sec . I also. can remember that ...
WORK = FORCE X DISTANCE
and. where. :
F .. is in pound ( lb )
d...is measured in ( feet ) always ..
UNTIL. . System International
( S I ) came. along .. learning and. Engineering measurement. changed. to. ...
newton .. ( Force. )
meter ... ( distance. )
It is. hard for me , but I. feel. happy. with. Sir. Jason guiding me in understanding the. subject. matter and. other. students too...
Very. good educational blessing. and help..
Thank you so much! Your organized, concise, and colorful visuals combined with the manner in which you break down the information is 👌🏼 Very grateful to be watching your videos❤
This was a great lesson, thank you! I also screen shotted the two atoms you drew because you inadvertently created a smiley face 😀, so some hidden fun!
That was a fascinating lesson. Thank you for taking the time to explain.
Great revision of what I learnt at school and university 50-odd years ago.
Thank you so much for these videos, such clear and passionate explanation!
There is only one thing in this video that maybe I missed or maybe it wasn't really important enough to note but I kept thinking the whole time you were talking about potential energy, you never really touched on how something gains potential energy, the energy that has to be put into it for it to be stored. Like lifting the box or clicking up the roller coaster. Anyways, most people should know that but I kept thinking it might make it come full circle for some people a little bit more. Not to criticize, I know you understand it much better than I do and have years of doing this, that was just one thing that I kept listening for is all.
As always wonderful lessons!
Thank you!
You've got it and I congratule you 👏🏻 Energy is everything. This is the stuff that makes me appreciate science. I loved your physics overview and electrical engineering stuff. You know what's important and have synthesized the value
It is a very good lesson and excellent teaching...!!!
THANK YOU... SIR...!!!
I love you and i someday want to teach like you because you are really a science genius
You flatter me! I am sure you will excel in your studies!
Thanks for the class . It reach all over the world. Which increases the knowledge of common people.
What a magnetic lecture it is!
Awesome teacher who made a difficult subject much simpler for me to understand.
Thank you, great teacher...
Great teacher...
Ma greatest teacher 🎉
Ohce again, a well explained concept
thanks for your nice explanation, could you please relate the kinetic energy to work like what you did for potential energy?
exquisite class
Perhaps it is worthy of mentioning..... as you said only you wished if someone had explained it to you right from day one. Based on that, the following maybe worthy of consideration.
You brought up Watt ( as if from nowhere), then explained it as joule/second. Lets wrap it nicely so it stands out clear. Maybe?
So here we go:
There are two types of joules. Mechanical joule and electromagnetic joule if you will.
Mechanical joule (work) is when 1kg of mass accelerating to a distance of 1 meter in the time frame of 1 second. Power is the measurement of this work/second. I.e. Mechaical joule/second.
Electric Joule: Displacing a coloumb of charges through a potential difference of 1V overcoming 1 ohm of resistance in one second. Notice how in this set up there is no mention of distance but mere displacement, more like some cross section if you will as if people just passing a door opening. That is rather interesting when it comes to electric joule. Thus; watt is this joule/second.
Is this about right?
Excellent
Thank you Jason...you kinetic me...
39:14 Don't worry Jason, we still stay awake😂
Lol good to hear!
You are great teacher thank you
thank you so much for the work that you’ve done (God Bless You). You’re a true teaching talent.
thank you for linking energy to chemistry and physics
all teachers should go through him before they cango on teaching chemistry and physics, a shame , aslo thankyou so much for this video
Thank you very much,Sir!
Welcome!
Really appreciate for your hard work to make people understand what reality of science is you are brilliant and great great teacher you deserve atleast millions views on your most videos 🙏🙏🙏🙏
Thanks so much. I appreciate your kind words!
thank you very much Man
Amazing.
Hello sir,I am 15 year old Indian ,and I want some guidance from you regarding chemistry ,well sir it goes like this.....i didn't study even a bit in covid lockdown, and now the schools are open, i am completely blank in the subject.......i literally dont know anything regarding chemistry...i now just watched your introduction of chemistry (6 year old video) ,it helped a bit ....but what should I do now ........like which videos, or topics should I start .....sir plz help I beg of you ...the anxiety is eating me inside out......plz sir I beg of you ....
Thank you for your fantastic video and enthusiasm! Also first!
Welcome and thank you!
999K .... breathe deep and release it ...then 1MILLION😁🕉️
congratulations for 1M
Thanks so much! Almost there!
Hello thank you for teaching me🎉
You are the best
At the beginning of this video the information you were ABOUT to share had the HIGHIST POTENTIAL ENERGY.
At the end of the video the information I received in my brain has the HIGHEST kinetic energy. Am I sorta close? LoL
Very nice 👍👍👍👍❤
happy 1 million subscriber sir jason😀
Thank you - almost there!!
For some reason I started to daydream about the relaxed state of the world and how much potential energy we've created to distance it from it.
I really liked this video series, where can I watch the following parts? For example 1-1-7? ( i think this is Nature of energy - part 2 probably?)
Hi, thank you Sir. Have a nice day.
You too!
thank you
at 28:00 he talks about burning (combustion) and is a very helpful explanation.
Thanks so much.
You are only like you, Sir.
So is the constant crashing waves of electrons on the nucleus what is making the quarks energized or move?
From Iraq and see your lesson 💜
If you had antimatter then could that mean the gravity formula could give you a repelling force (I.e. a negative number like you get if the + vs - in the electric force equation)?
Hello! In which package can i find this leasson?
Can the Total Atomic Numbers involved be an indicator of the amount of Energy involved in a Chemical Reaction,?
For instance -- Does the production of Hydrochloric Acid from H2 + Cl2 ....... Require more Energy than the production of Water from H2 + O2?
What is the difference between Work and Kinetic Energy?
think you sir very mutch your explecation is very eazey
Thank you!
Thank u prof
Welcome!
Where were you when I was in these classes. I did well in physics but it’s just remote memorization- there is no context to connect concept
watches 1 lesson on physics and work, me: "I think I got a shot at applying to Nasa"
Omg you are too close to reach 1M subs
Yes so close!!! Maybe tomorrow! Thank you so much!
Please make a video of optics...
Will do!
Where's part two? ,Teacher
I searched a lot
What's the different between psychic and mathematics
work is effort exercise alone group
But at the bottom, the box is not moving, and KE seems to be zero.
where is episode 5? please
🔥🔥🔥
Thank you so much!
ke 1/2 (1200) (324)
20:00
When he says breaking bonds is Chemistry, he is referring to electronic chemistry. Nuclear Chemistry is governed by different rules and thusly different "bonds"...
ke=1/2 mv2
Good but not enough (still a lot of work for deeper understanding)
potential energy is somthing which wants to move
Not bad
8:29am10:53-89/1/24
What if the potential energy is at ZERO when on the ground, and the ground caved in, will you go from O to negative numbers?
No, energy is scalar( meaning only has quantity not direction) so when you cave in you will create new height(still positive number)
@@evlereldensmaa7073
Thanks
@@kamalibrathwaite I disagree with your previous respondent. Potential energy can be negative. It just means that the potential energy is less than the potential energy at the location we arbitrarily define as zero.
For GPE on this planet where g is close enough to uniform, this just means you pick a location, give it a zero z-position, and anything lower than that z-position will have negative potential energy. Usually you pick a location such as the floor, the ground, or sea level as this datum. It ultimately is differences in potential energy that you care about, so where you define zero potential energy makes no difference in any applications of the concept.
For GPE in the universal sense, with GPE = -G*M*m/r, there is a convention to establish GPE to equal zero, when r=infinity. This is simply for mathematical convenience, because we simply set the +C term equal to zero, after integrating, so we keep it simple and don't need to determine what C equals.
For electric potential energy, if there is a location where positive EPE exists, then if you simply switch the sign of the charge, you would then have negative EPE at that same position. Again, EPE is defined with an arbitrary datum just like GPE, and it is ultimately differences in EPE that we care about.
1200x324= 4800+ 2400 + 3600
ke=1/2 1200 18x18= 144+ 18= 324
