Momentum+Impulse

Front

The momentum of an object depends upon the object's ___________ & ___________.

Back

mass and velocity

Front

A 5 N force is applied to a 3 kg ball to change its velocity from +9 m/s to +3 m/s. What is the impulse on the ball?

Back

-18 N s

Front

A bicycle has a momentum of 24 kg•m/s. What momentum would the bicycle have if it had the twice the mass and was moving with twice the speed?

Back

4x the momentum; 96 kg*m/s

Front

A bicycle has a momentum of 24 kg•m/s. What momentum would the bicycle have if it had the same mass and was moving with one-half the speed?

Back

1/2 the momentum; 12 kg*m/s

Front

A 3 kg cart has a momentum of 18 kg m/s. What is its velocity?

Back

6 m/s

Front

Define momentum.

Back

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

Front

What is impulse?

Back

Impulse is the change in momentum of an object when a force is applied over a period of time, calculated as Impulse = Force × Time.

Front

How does increasing mass affect momentum?

Back

Increasing the mass of an object increases its momentum if the velocity remains constant.

Front

How does increasing velocity affect momentum?

Back

Increasing the velocity of an object increases its momentum if the mass remains constant.

Front

What is the relationship between impulse and momentum?

Back

Impulse is equal to the change in momentum of an object: Impulse = Δp.
