# 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 Conservation law stating that the total linear Momentum of a closed system remains constant through time, regardless of other possible changes within the system.

A sticky collision is when two objects with the same mass collide and stick together. A non-sticky collision is when two objects with the same mass collide but don't stick together.

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

Example of an Elastic Collision

A perfectly elastic collision is defined as one in which there is no loss of kinetic energy in the collision. An inelastic collision is one in which part of the kinetic energy is changed to some other form of energy in the collision.

Example of an Elastic Collision

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.
