Acceleration Galileo's Inclined Plane

Galileo's Incline plane lab activity for acceleration.

Acceleration: Galileo's Inclined Plane

In Galileo's time, stopwatches had not been invented. He needed a way to measure the short time it took for a ball to roll down an incline. The set-up you will use is nearly identical to what Galileo would have used. Just like Galileo, students will measure the time it takes for a ball to roll down an incline by the amount of water released during the roll. We will use this time measurement to calculate the acceleration of the ball at different heights and compare them.

Required Equipment
Inclined Plane, Ball, Burette, Burette Clamp, Ring Stand, beaker, funnel, water

The lab can be easily modified to use a regular stopwatch for timing. It is less authentic, but the results are the same.
