Momentum and Energy

  1. Apr 29, 2008 #1
    An isolated system is initially at rest. Is it possible for parts of the system to be in motion at some later time? Explain.

    When driving a golf ball, a good 'follow-through' helps to increase the distance of the drive. Explain why this technique allows you to hit the ball farther.

    This is false, after the ball leaves the club after the collision, it doesn't matter what the golfer does with the club.

    Initial momentum is zero, which is a vector quantity.
    certainly one part can have motion after some time, considering the fact that you are not restricting the motion of the other part.
    example: BOMB explosion
