Front

What is the unit for momentum?

Back

kg x m/sec

Front

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

Back

mass and velocity

Front

The equation to calculate momentum is

Back

p = m x v

Front

Which of the following scenarios involves a positive change in momentum (ΔP) equal to 14,000 kg • m/s?

Back

A 3,500 kg truck increases its velocity from 7 m/s to 11 m/s

Front

If an object has a momentum of 40 kg x m/s and a mass of 60 kg, what is its velocity?

Back

.67 m/s

Front

Define momentum.

Back

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

Front

What is the formula for calculating momentum?

Back

p = m x v

Front

How does mass affect momentum?

Back

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

Front

How does velocity affect momentum?

Back

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

Front

What happens to momentum in a closed system?

Back

Momentum is conserved in a closed system, meaning the total momentum before an event equals the total momentum after.
