Momentum Pracitce

Front

What is momentum?

Back

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

Front

What is the formula for calculating momentum?

Back

The formula for calculating momentum is p = mv, where p is momentum, m is mass, and v is velocity.

Front

What are the units of momentum?

Back

The units of momentum are kg·m/s (kilogram meter per second).

Front

What is an elastic collision?

Back

An elastic collision is a type of collision where both momentum and kinetic energy are conserved.

Front

What is an inelastic collision?

Back

An inelastic collision is a type of collision where momentum is conserved, but kinetic energy is not.

Front

Calculate the momentum of a 50 kg ball rolling at 5 m/s north.

Back

250 kg·m/s north.

Front

Calculate the momentum of a 55 kg running back moving at 10 m/s west.

Back

550 kg·m/s west.

Front

What happens to momentum in a closed system?

Back

In a closed system, the total momentum before and after an event (like a collision) remains constant.

Front

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

Back

It is an inelastic collision.

Front

What is the principle of conservation of momentum?

Back

The principle states that the total momentum of a closed system remains constant if no external forces act on it.
