Conservation of Momentum

Front

What is the Law of Conservation of Momentum?

Back

The Law of Conservation of Momentum states that the total momentum before a collision is equal to the total momentum after a collision.

Front

When two objects collide, what happens to their momentum?

Back

According to the Law of Conservation of Momentum, momentum is neither lost nor gained during a collision.

Front

If a person on a stationary skateboard throws a bowling ball with a velocity of 5.0 m/s, what is a possible speed of the person after the throw?

Back

1.5 m/s

Front

In a collision, how does the momentum before compare to the momentum after?

Back

The momentum before the collision is equal to the momentum after the collision.

Front

What is the formula for momentum?

Back

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

Front

If a 9300 kg railroad car traveling at 5 m/s strikes a 5000 kg boxcar at rest, what speed will the second boxcar move if the first boxcar is at rest after the collision?

Back

9.3 m/s

Front

What is an example of a real-life application of the conservation of momentum?

Back

A game of pool where the cue ball strikes the other balls, transferring momentum.

Front

What happens to the total momentum in an isolated system?

Back

The total momentum remains constant in an isolated system.

Front

Define elastic collision.

Back

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

Front

Define inelastic collision.

Back

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