# Momentum

* Momentum* is the quantity of motion of a moving body, measured as a product of its mass and velocity.

Momentum = (mass)(velocity) p=mv

* Conservation of Momentum*. A

*law stating that the total linear*

**Conservation***of a closed system remains constant through time, regardless of other possible changes within the system.*

**Momentum**A * sticky collision* is when two objects with the same mass collide and stick together. A

*collision is when two objects with the same mass collide but don't stick together.*

**non-sticky**** Angular momentum:** Is the measure of the amount of rotation an object has. This has to do with outer space because the sun orbits around the earth. And the amount of rotation the sun has is its

**Angular Momentum**The ** letter P** represents momentum because it came from the Latin word "petere" which means "to go forward".

An * elastic collision* is an encounter between two bodies in which the total kinetic energy of the two bodies after the encounter is equal to their total kinetic energy before the encounter.

*occur only if there is no net conversion of kinetic energy into other forms.*

**Elastic collisions**A perfectly * elastic collision* is defined as one in which there is no loss of

It is the type of collision if you throw a piece of clay at the ground would be inelastic collision because when the clay hits the ground it stops, so its energy was not lost.
