Galileo's Track

by: Bruce Yeany

Galileo's track is made from one long continuous rail that joins two different angled ramps together. The first ramp has a short, steep slope. After a ball rolls down the first ramp, it will then roll up a longer gently sloping part of the track on the opposite ramp. With both sides of the track at the same height, the questions to be asked center around how far a ball will roll up the opposing hill when released from either of the sides. This chapter highlights how with such a track Galileo studied the motion of objects and it led him to the concept of inertia.
