Power, Impulse, Momentum, and Collisions

Front

What is a perfectly inelastic collision?

Back

A collision where two objects stick together and move with the same final velocity.

Front

What happens in an elastic collision?

Back

Two objects bounce off each other and move separately, conserving kinetic energy.

Front

What is an inelastic collision?

Back

A collision where two objects bounce off each other but kinetic energy is not conserved.

Front

How is momentum calculated before a collision?

Back

Front

What is the law of conservation of momentum?

Back

The total momentum of a closed system before and after a collision remains constant.

Define momentum.

Front

What is the difference between elastic and inelastic collisions?

Back

In elastic collisions, kinetic energy is conserved; in inelastic collisions, it is not.
