watched this 2 years ago when i started physics, finally followed along through the entire thing two years later! i call that growth

[@yoprofmatt]

It only took two years to finish watching this? Noice. Cheers, Dr. A

[@aaryan_astron]

I am a physics majoring 1st year student...and I'm trying to clear my every concept...you are the one who is helping very well

[@rashmideka1522]

Sir you're simply awesome, your explanation of the concepts are superb too!!

[@yasminnavesgeurtsen364]

You're explanations are straight to the point, no time wasted! And very easy to understand. Thank you!!

[@yoprofmatt]

You're welcome. Thanks for watching. Cheers, Dr. A

I tower over the weasel Einstein. The maria occupy one third of the visible NEAR side of WHAT IS THE MOON. This IS fundamentally related to the surface gravity of what is THE MOON. Attention: The rotation of what is the Moon matches the revolution. Now, consider the gravity of THE SUN !!! By Frank Martin DiMeglio

[@jeremycuster8025]

I sure wish you were teaching physics at my school! You do a great job of explaining the concepts and how the equations are derived. Thank you!

[@yoprofmatt]

+Jeremy Custer Jeremy, thanks for the note. Sorry you're not happy with your instructors, but very glad to be of help. Cheers, Dr. A

[@amirazammit6972]

@Harvey Forrest me too

[@conornoel9149]

you prolly dont give a damn but does someone know of a way to log back into an instagram account? I stupidly lost my account password. I would appreciate any tips you can give me.

[@travisdeclan1701]

@Conor Noel instablaster ;)

[@conornoel9149]

@Travis Declan thanks so much for your reply. I got to the site on google and im waiting for the hacking stuff now. Looks like it's gonna take a while so I will reply here later with my results.

[@steffenleo5997]

Thanks Prof Anderson for these great explained topic... 👍👍

[@linatewala9471]

Thank you! You make everything just easier to understand.

[@willwicky9052]

Thank you so much for interviewing me for the open sales position. I appreciate the time you spent explaining the hiring process and how your training program works. You’re clearly very knowledgeable about sales and marketing. I enjoy working in sales and believe I would be an excellent fit for the position. I love a challenge, and your innovative training program intrigues me. As we discussed during the interview, my sales numbers at my current job increased by 50 percent over the past three years, and I was at the top of our sales force last year. I’m confident that combining my current experience with your training program will allow me to reach the top of your sales force as well. Thank you again for taking the time to talk to me about the position. I believe I can benefit your company and look forward to meeting again soon. In the meantime, please let me know if you need any additional information. Sincerely, Your Handwritten Signature (for a hard copy letter) Joseph Q. Applicant

[@siddhantjadhav7570]

Such a simplification of concept of Work and Potential Energy.. Thank you very much sir..

[@yoprofmatt]

No problem. You are welcome. Cheers, Dr. A

[@chahkuneng6299]

Much thank for your influence explanation that you made.

[@shadabimam8222]

Not able to concentrate on this vdo bcz each tym i do my mind goes to his great ability of writing inverse!!!!

[@yoprofmatt]

Hate to burst your bubble, but I'm not writing backwards. Simple horizontal flip of the image: www.learning.glass Cheers, Dr. A

[@alyattalla8520]

lol

[@roshan0405]

Thanks Deadpool ❤

[@ImranKhan-gw5qv]

Sir are you alive?I have seen it after 10 years and successfully understanded it

[@ibrahimnizamani4958]

I don't get, how you took r(initial) approaches to infinity. Can you elaborate it abit please?

[@sushantsingh8700]

Honourable Sir, I Have a question, what about a object placed at rest, does it have potential energy (it has no other contact.) A student from India... Thanks

[@moaathkhaled4662]

Thanks ❤

[@Propdesk_Trader]

Do you have to learn to write backwards to use that board?

[@sushantsingh8700]

A ball placed at a top a hill always wanted to go downwards direction as it has potential energy at top of hill and realises it and it rolls down as in motion uses kinetic energy. But what that the place where the Object (ball) assume that it is in the rest position is not at the rest it have to go more downward it is in a false vacuum, what will happen then..

[@mhakash8967]

thank you sir...take love from bangladesh🇧🇩

[@yoprofmatt]

Hello Bangladesh! I take your love and send it back twice over. Great to meet another Fanderson™ Cheers, Dr. A

[@fatihzengin8126]

You are amazing.Thanks to you ı love physics.Thank you :)

[@TeacherNorainikhal]

Why set reference point at infinity not the centre of the earth

[@tianhanipah9783]

Best ✨💯

[@chiranrajamanthree7788]

🔥

[@sparshgupta4300]

How they make these types of vdo

[@aspirants2280]

Sir please upload a video on acceleration due to the gravity

[@yoprofmatt]

Himanshu, Working on new ones soon. You might also like my new website: www.universityphysics.education Cheers, Dr. A

[@ptyptypty3]

what if we decided to make the center of the EARTH our Zero REFERENCE point?.. then figure out the PE for any mass above the earth and throughout the universe... that is, if we are truly Free to pick any reference point.. I'll have to give this a shot and see.. :) .. as usual, Clear and Concise video Prof Matt... thank you !!

[@hazal541]

Best explanation !

[@yoprofmatt]

Thanks! Keep up with the physics. Cheers, Dr. A

[@samialsharari4771]

How come we reached to potential energy from integrating the work?

[@Andre-ql2ei]

You’re a blessing

[@yoprofmatt]

Andre' _1670, Great comment, thanks. You might also like my new website: www.universityphysics.education Cheers, Dr. A

[@siddhantjadhav7570]

A small Doubt sir: If the mass of the body is not constant, if it changes due to some non conservative forces, then how to proceed for integration???

[@yoprofmatt]

Interesting question. So perhaps the mass is disintegrating as it moves upward? I suppose then F would be a function of height and the integral gets more complex. I'll have to think about an example for that one. Cheers, Dr. A

[@siddhantjadhav7570]

+Matt Anderson Can we take example of a rocket which took off with a mass M and there is decrease in mass as time passes?? In this case what will be the work done by gravity??

[@ashleyvince7]

How do you write it inverse! ?

[@TheBigBanggggg]

www.learning.glass

[@mytech6779]

Just flip the video

[@syedumamah5078]

If we dont lift block it still has potential energy, where does this potential enegy come from since we havent given any external force to block and we know internal forces usually balance and they are not able to do any work?

[@yoprofmatt]

Syed Umamah, Thanks. Not sure exactly what you're asking, though. Join the discussion at my new website: www.universityphysics.education Cheers, Dr. A

[@boptah7489]

And so. The box has no potential energy at all. . The box is under the force of gravity. so gravity is the force. The box does not store Gravitational force.

[@daltanionwaves]

Is he writing backwards?

[@wolfy9979]

What is the difference between this G.M.m/r^2 and -G.M.m/r? Like for what do you use the second one and why?

[@yoprofmatt]

Werewolf, The units reveal all. One is force, the other is energy. Thanks for the comment, and keep up with the physics! You might also like my new website: www.universityphysics.education Cheers, Dr. A

[@frankdimeglio8216]

Consistent WITH WHAT IS E=MC2 (AND TIME), “mass"/ENERGY involves BALANCED inertia/INERTIAL RESISTANCE consistent WITH/as what is BALANCED electromagnetic/gravitational force/ENERGY. By Frank Martin DiMeglio

[@sanketpatil8557]

nice

[@izzeldeenmez4343]

6:33 4:37?

[@gurushajuneja1946]

Hey ! Dr Matt Anderson wheee do you teach?

[@Taricus]

6:44

[@danielzlotin6607]

is that a mirror? how does he doing that?

[@yoprofmatt]

daniel zlotin, Not writing backwards (I'm not that talented). The board is called Learning Glass. You can check it out at www.learning.glass Cheers, Dr. A

[@mikiutpost]

Its 1 in the aire and 0 in the grund and revers that IF U can Its also b-

[@mikiutpost]

Net force 1/4 ecuels 3/4 in input energy

[@boptah7489]

There is no evidence that the force of gravity is a function of Mass only. . So the gravitational force formula is moot.

[@devanshkatheria]

so u seriously writing everything reversed!!!!!

[@yoprofmatt]

Not that talented. A simple "mirror-image" flip of the video does the trick. See it here: www.learning.glass Cheers, Dr. A

[@devanshkatheria]

Matt Anderson Ohk😮...BT u teach it really simpified sir..thank u

[@tanialu7499]

Has anyone ever told you that you look like Doctor Strange?

[@shrekssexydad7087]

My cousin sent this to me and i’m 13 i’m too dumb for this- 👁👄👁

[@anchovybushwack472]

I'm trying real hard to focus, but the noise of that goddamn marker
