Kinetic energy and conservation of energy go together?

  1. Feb 10, 2006 #1
    How do Newton's third law, mass, acceleration, impulse, inelastic and elastic collisions, momentum, conservation of momentum, kinetic energy and conservation of energy go together?

    can you specify a bit? Becuase else i can write it all down for you but that would take quite a few hours.

    What do you mean by specify?

    I could tell you about:
    F = ma
    p = mv[/tex]

    or any other forumla or relationship. If i were to go over everything (as the thing you asked for covers alot) it wouls take a huge amount of time. Can you make your question a bit...smaller so that it does cover so much?

    I'll try...

    What I am looking for, is how these things are used in physical interactions.

    Ok i see. So you are basically looking for definition of those?
  8. Feb 11, 2006 #7
    I think the definitions would be good.

    ok, i'll give it a shoot

    (posting this reply to keep people from replying b4 i'm done since it is alot to write)

    Newton's third law of motion:

    As the name sounds it is the third law of motion made up by Issac Newton. Its definition is:

    "Every action has an equal and opposite re-action"

    So if you shot with a pistol, the gun will apply a force on the bullet making it fly away. You will feel a recoil from the weapon. If you try to pull a spring the spring will try to pull back. If you hit a ball, the ball also affects your hand with the same force but in exactly the opposite direction. This also aplies for impulse which i'll come to later.


    Mass is a measurement that tells you how much force you feel from a body divided by acceleration of gravity.

    Now i'm to tired to define the rest in this post. Will try more tomorrow.

    you can also try google:

    type in

    define: impulse

    and you will have clear defination of what it is. then try the rest aswell
