Physics of Motion

Motion ModuleHow Far Can You Hit the Ball?

by Ben Higgins, Caleb Bryce and Stephen Buchter

Objects are in motion all around us, yet it is often difficult to measure even the basic properties of moving objects such as their velocity, acceleration, or turning angles. Fortunately, a freely available software, called Tracker, lets you measure the underlying mechanics for any object in motion. All you need is a computer and a video of the motion that you’d like to investigate. This module uses a baseball bat swing to show how the Tracker software works.

This module is an opportunity for students to: 1) Learn how to use the Tracker software, 2) Hypothesize what factors are responsible for how far a batter can hit a ball, 3) See how far they can hit the ball, and 4) Test a hypothesis and then interpret and communicat the results.

A SCWIBLES video that explains the use of "Tracker", a free software app. Tracker allows you to gather physics data on the motion of any moving object seen in a video.
