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
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.
@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.
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
I have a question. If you were to set r intitial to infinity, that means we are applying an external force to the body opposite to the direction of The conservative force. The body moves from infinity to r final(within the field of The Mass M). So, we are doing a negative work here. But earlier you took the angle for dot product 0 degree. Shouldn't it be 180? 5:43
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
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..
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
+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??
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?
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 !!
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
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.

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
