Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity.

Front

What units are used to measure momentum?

Front

What happens to momentum in a closed system during a collision?

Back

Momentum is conserved.

Front

If two objects collide and stick together, what type of collision is this?

Back

Inelastic collision.

Front

What is the principle of conservation of momentum?

Back

In a closed system, the total momentum before an event is equal to the total momentum after the event.

Front

How does mass affect momentum?

Back

Greater mass results in greater momentum if velocity is constant.
