Front

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

Back

velocity

Front

Write the equation for momentum (all lowercase, no spaces)

Back

p=mv, p=vm

Front

Momentum is a...

Back

Vector that points in the same direction as velocity

Front

Impulse is the effect of a force acting over a period of...

Back

time

Front

Object A and Object B collide. Which of the following is true?

Back

Object A and Object B will have the same magnitude of momentum change, but one will gain and one will lose.

Front

What is the unit of momentum?

Back

kg·m/s

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.

Front

Define impulse in terms of momentum.

Back

Impulse is the change in momentum of an object when a force is applied over a period of time.

Front

What is the formula for impulse?

Back

Impulse = Force × Time

Front

How does mass affect momentum?

Back

Greater mass results in greater momentum if velocity is constant.
