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

      It only took two years to finish watching this? Noice.

      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 !!!

      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)

    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

  • @sushantsingh8700
    @sushantsingh8700 4 ปีที่แล้ว +1

    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..

  • @sushantsingh8700

  • @siddhantjadhav7570
    @siddhantjadhav7570 6 ปีที่แล้ว +1

    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
      @yoprofmatt  6 ปีที่แล้ว +1

      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.

      Dr. A

  • @syedumamah5078
    @syedumamah5078 4 ปีที่แล้ว

    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 !!

    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.

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