Momentum and Impulse

Front

What does a trampoline increase, which in turn decreases force?

Back

A trampoline increases time, which in turn decreases force.

Front

What is the equation to calculate momentum?

Back

p = mv

Front

Calculate the momentum of a 1000-kg car moving southward at 20 m/s.

Back

20000 kg*m/s south

Front

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

Back

250 kg*m/s

Front

What happens to momentum when the speed of an object is doubled?

Back

The momentum doubles.

Front

Define momentum.

Back

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

Front

How is impulse related to momentum?

Back

Impulse is equal to the change in momentum (Impulse = Δp = FΔt).

Front

What is the unit of momentum?

Back

The unit of momentum is kg*m/s.

Front

If a 2 kg object is moving at 3 m/s, what is its momentum?

Back

6 kg*m/s.
