Momentum & Collisions

Front

What is the equation to calculate momentum?

Back

p = mv, where p is momentum, m is mass, and v is velocity.

Front

When is momentum conserved in a collision?

Back

Momentum is conserved in all collisions, whether elastic or inelastic.

Front

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

Back

Total momentum is conserved.

Front

What type of collision occurs when objects bounce apart?

Back

Elastic collisions.

Front

What type of collision occurs when objects stick together after colliding?

Back

Inelastic collisions.

Front

Define momentum.

Back

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

Front

What is an elastic collision?

Back

An elastic collision is one in which both momentum and kinetic energy are conserved.

Front

What is an inelastic collision?

Back

An inelastic collision is one in which momentum is conserved, but kinetic energy is not.

Front

Give an example of a real-world elastic collision.

Back

Two billiard balls colliding and bouncing off each other.

Front

Give an example of a real-world inelastic collision.

Back

A car crash where the vehicles crumple together.
