Momentum

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

Conservation of Momentum: a conservation law stating that the total linear momentum of a closed system remains constant through time.

P=MV is the formula for momentum where P represents momentum

Why does P stand for momentum and not M?  M for momentum would be confused with M for mass in the equation so they used the symbol P.

It's kind of crazy how a moving van and a motorcycle can have the same momentum even though its quite simple. The formula is P=MV so the van could be going slow and the motorcycle fast. If the van weighs ten times the motorcycle and is going 5 mph it would have the same momentum as the motorcycle going 50 mph.

There are two types of collisions. A sticky collision or a non-sticky collision. The difference is in a sticky collision the two share the kinetic energy. If the total kinetic energy is not conserved, then the collision is referred to as a sticky collision.

Sticky Collision

Non-Sticky collision

Throwing a piece of clay on the ground would be a sticky collision because the object doesn't move afterwards and the kinetic energy wouldn't be conserved.

An angular momentum is the quantity of rotation of a body, which is the product of its moment of inertia and its angular velocity. It has to do with space because it helps the planets rotate around the sun.
