Impulse Momentum Theory Practice

Front

What does the impulse-momentum theorem state?

Back

The impulse on an object is equal to the change in momentum it causes.

Front

If Cart A is pulled with a 2 Newton force for 2 seconds and Cart B with a 1 Newton force for 3 seconds, which cart experiences the greatest impulse?

Back

Cart A experiences the greatest impulse.

Front

What is the change in velocity of a 7.2-kg object acted upon by a constant force of 4.5 N for 10.0 s?

Back

6.3 m/s.

Front

Which requires more force to catch, a bowling ball or a ping pong ball?

Back

A bowling ball requires more force to catch because it has more momentum.

Front

How can a tennis ball and a bowling ball have the same momentum?

Back

They can have different speeds.

Front

Define impulse in physics.

Back

Impulse is the product of the average force applied to an object and the time duration over which it is applied.

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity.

Front

How is impulse related to momentum?

Back

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

Front

What is the formula for calculating impulse?

Back

Impulse = Force × Time.

Front

What is the unit of impulse?

Back

The unit of impulse is Newton-seconds (Ns) or kg·m/s.
