What is Momentum?

Characteristic of a moving object that is related to the mass and the velocity of the object.

Momentum Formula

Momentum=Mass x Velocity

What is the Law of Conservation of Momentum?

"In the absence of outside forces like friction, the total momentum of objects that interact does not change."

Why does the letter "P" Represent Momentum?

"P" came from the latin word petere which means "go towards", and "m" would have been too confused with "mass".

How can a heavy moving van have the same momentum as a small motorcycle?

Since momentum is equal to mass times acceleration this means a motorcycle can be accelerating quickly while having less mass and still have the same momentum.

What is a sticky and non-sticky collision?

A sticky collision is when two objects stick together in a collision. A non-sticky collision is when two objects of the same mass don't stick together and outside forces are so small that the objects just trade velocities.

This is an elastic collision. 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.

This is an inelastic collision. An inelastic collision, in contrast to an elastic collision, is a collision in which kinetic energy is not conserved.

What type of collision would you think throwing a piece of clay onto the ground would be and why?

Inelastic Collision because the clay would not bounce back up.

What is Angular Momentum? What does it have to do with outer space?

The quantity of rotation of a body, which is the product of its momentum of inertia and its angular velocity. It occurs on the rotation axis of planets or moons.
