Momentum Collision

Front

What does the momentum of an object depend on?

Back

Mass and velocity.

Front

Which has more momentum: a car stopped at a red light or a bike moving at 15 mph?

Back

A bike moving at 15 mph has more momentum.

Front

Which of the following has the least amount of momentum? An ant walking along the ground, An ant at rest, An elephant walking, An elephant running.

Back

An ant at rest has the least amount of momentum.

Front

What type of collision occurs when pool balls bounce apart?

Back

Elastic collision.

Front

What type of collision occurs when Steve jumps onto a tube and stays in it?

Back

Inelastic collision.

Front

Define momentum.

Back

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

Front

What is the formula for calculating momentum?

Back

Momentum (p) = mass (m) × velocity (v).

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 perfectly elastic collision.

Back

A collision between two identical billiard balls.
