Momentum Practice

Front

What is Newton's First Law?

Back

An object in motion stays in motion and an object at rest stays at rest unless acted on by an outside force.

Front

What is the definition of momentum?

Back

Momentum is defined as mass in motion.

Front

What happens to the overall momentum when two objects collide and stick together?

Back

The overall momentum will stay the same.

Front

True or False: Weight is a Force.

Back

True.

Front

Calculate the momentum of a biker with a mass of 75 kg moving at a velocity of 5 m/s.

Back

375 kg m/s.

Front

What is the formula for calculating momentum?

Back

Momentum = mass x velocity.

Front

What is the unit of momentum?

Back

The unit of momentum is kg m/s.

Front

How does mass affect momentum?

Back

Greater mass results in greater momentum if velocity is constant.

Front

How does velocity affect momentum?

Back

Greater velocity results in greater momentum if mass is constant.

Front

What is the principle of conservation of momentum?

Back

In a closed system, the total momentum before an event is equal to the total momentum after the event.
