Momentum

Front

What is momentum?

Back

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

Front

How is momentum calculated?

Back

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

Front

What is the unit of momentum?

Back

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

Front

If a runner has a momentum of 720 kg m/s and is traveling at a velocity of 5 m/s, what is his mass?

Back

144 kg

Front

What is the momentum of a 0.250 kg cart moving at 0.400 m/s?

Back

0.1 kg·m/s

Front

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

Back

550 kg·m/s, west

Front

What does Newton's First Law state?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is Newton's Second Law?

Back

Force equals mass times acceleration (F = ma).

Front

What is Newton's Third Law?

Back

For every action, there is an equal and opposite reaction.

Front

What is the relationship between mass and momentum?

Back

Momentum increases with an increase in mass if velocity remains constant.
