Total Momentum

Front

Define momentum.

Back

Momentum is the product of an object's mass and its velocity (p=mv).

Front

What is the unit of momentum?

Back

Kilogram meter per second (kg·m/s).

Front

What does it mean for momentum to be conserved?

Back

It means that the total momentum of a closed system remains constant before and after a collision.

Front

What is an elastic collision?

Back

A collision where both momentum and kinetic energy are conserved.

Front

What is an inelastic collision?

Back

A collision where momentum is conserved, but kinetic energy is not.
