In this lesson, we will learn how to use the formula for momentum, p = mv, to calculate the momentum of objects and calculate changes in an object's momentum.

Q1:

A tennis ball with a mass of 60 g is thrown at a wall, hitting it while moving at a speed of 15 m/s. The ball bounces back from the wall with a speed 10 m/s. What is the magnitude of the tennis ball’s net momentum change due to the collision?

Q2:

A snowball rolls down a snowy hillside, and as more snow sticks to the snowball, it increases in mass. The graph shows how the snowball’s mass and velocity change.

How much does the momentum of the snowball increase from when its velocity is 5 m/s to when its velocity is 10 m/s?

By how much would the momentum of the snowball have increased when its velocity changed from 5 m/s to 10 m/s if no snow stuck to it as it rolled?

Q3:

The graph shows the change in momentum of an object as its velocity changes. What is the mass of the object?
