Friction is essential to all ball sports, but is more obviously important if the ball is rolling on a surface. Which ball sports require a ball to roll on a surface as a critical component of the sport? Name as many sports as possible.

Consider the following graph, excerpted from the book series Bounce, Roll, & Fly: The Science of Balls from Schottenbauer Publishing:

Discussion Questions:

- What is the initial velocity of the ball?
- What is the final velocity of the ball?
- What is the initial momentum of the ball?
- What is the final momentum of the ball?
- What is the initial kinetic energy of the ball?
- What is the final kinetic energy of the ball?
- How far does the ball travel?
- Given the same initial velocity, would this ball travel further on a gym floor? On grass?

Lab manuals from Schottenbauer Publishing can supplement traditional curricula in math, physical science, physics, and physical education. They can also be integrated into summer camp and other summer academic enrichment activities, from approximately age 10 and onward. Ideas for lesson plans can be found in the blog Graphs in Education.
