Newton's First Law on an Air Track

Demonstrate both parts of Newton's First Law


air track and glider


Be sure that the air track is level, and that it has room to move on the table.

You can demonstrate "objects at rest" by giving a sharp acceleration to the air track while the glider is at rest - HINT: Be sure that you have enough room to do this without sending the air track to the floor! Also, be sure that the air track moves along its long axis only - any sideways motion will make the glider move!

Demonstrating the "objects in motion" part of the 1st Law is pretty obvious, I hope.
