Kinetic Energy = Energy Associated with Motion

1/2 mass * Velocity * Velocity = 1/2mv2

Momentum is Mass * Velocity = mv

Conservation of Momentum is a rule of mechanics. your intution has already told you about it.

Consider hitting a baseball. The bat, with some mv, makes impulsive contact with a ball - mbat is greater than mball and since:

(mv) bat = (mv) ball

then vball is greater than vbat (provided that you hit the ball and not just air).
