Momentum

MOMENTUM:The product of an objects mass and velocity.

Law of conservation of mass:The law that in the absence of outside forces the total momentum of objects that interact does not change.

Formula for momentum: momentum(or p) = mass times velocity

No one is quite sure why "p" is used for momentum. It likely came from the Latin word petere which means go towards. They couldn't use m because that was already used for mass.

A heavy moving van can have the same momentum as a small motorcycle because an object has more momentum if it is bigger, or if it is going faster,the motorcycle could be going faster than the van.

A sticky collision is where no kinetic energy is lost, and non-sticky collision is where some of the kinetic energy of the colliding bodies is lost.

Throwing a piece of clay on the ground would be inelastic collision because, the clay would stick to the ground and lose some of its colliding energy.

Angular momentum:When the object spins around and around instead of going straight like a train. All of the planets have angular momentum, and it also never stops spinning.
