What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the formula p = mv.

Front

What is the Law of Conservation of Momentum?

Back

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

Front

What happens to momentum in a perfectly elastic collision?

Back

In a perfectly elastic collision, both momentum and kinetic energy are conserved.

Front

What happens to momentum in an inelastic collision?

Back

In an inelastic collision, momentum is conserved, but kinetic energy is not.

Front

How do you calculate momentum?

Back

Momentum (p) is calculated using the formula p = mv, where m is mass and v is velocity.

Front

If two objects collide and stick together, what type of collision is it?

Back

It is called a perfectly inelastic collision.

Front

What is the unit of momentum?

Back

The unit of momentum is kilogram meter per second (kg·m/s).

Front

If a 4 kg box moves at 12 m/s, what is its momentum?

Back

The momentum is 48 kg·m/s (p = mv = 4 kg * 12 m/s).

Front

What is the relationship between mass, velocity, and momentum?

Back

Momentum increases with either an increase in mass or an increase in velocity.

Front

What is the momentum of a stationary object?

Back

The momentum of a stationary object is zero, as its velocity is zero.
