Conservation of Momentum

Front

What does the Law of Conservation of Momentum state?

Back

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

Front

If two skaters push off each other, what can be said about their velocities if one has a smaller mass?

Back

The skater with the smaller mass (Skater 1) will have a greater velocity than the skater with the larger mass (Skater 2).

Front

In any collision, what quantity is always constant?

Back

Total Momentum.

Front

What happens to the velocity of a big fish after it swallows a small fish at rest?

Back

The big fish has less velocity after swallowing the small fish.

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

Define momentum in physics.

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

Explain the concept of 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

How does mass affect momentum?

Back

An increase in mass will result in an increase in momentum if velocity remains constant.
