When two bodies collide with each other in the absence of an external force, then the total final momentum of the bodies is equal to their total initial momentum.
A change in an object's speed has a(n) _________ effect on its kinetic energy than a change in its mass = <span>A greater effect.</span>
Mass of a sample of gas doesn't change, no matter what happens to its pressure, volume, or temperature.
The highest point<span> of the </span>pendulums<span> swing is when the potential energy is at its </span>highest<span> and the </span>kinetic energy<span> is at its lowest.</span>
