Front

What is an elastic collision?

Back

An elastic collision is an encounter between two bodies in which the total kinetic energy of the two bodies remains the same.

Front

What is an inelastic collision?

Back

When two objects collide, becoming stuck together and internal kinetic energy is lost (but not really lost, it transfers to different forms of energy).

Front

How is kinetic energy affected in an inelastic collision?

Back

Kinetic energy is partially lost to other forms of energy.

What is the main difference between elastic and inelastic collisions?

Back

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

Front

What happens to kinetic energy in a perfectly inelastic collision?

Back

The maximum amount of kinetic energy is lost, and the objects stick together.

Front

What is momentum?

Back

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