How It Is Used
The ball is released from different heights on the incline and students watch whether it completes the loop or falls away near the top. The lowest successful starting height is then related to the critical speed at the top of the loop and to the conversion of potential energy into kinetic energy.
Frequently Asked Questions
Why does the Loop the Loop Apparatus have more than one starting point?
The high and low entry points send the ball into the loop at different speeds, so students can find from which height it has enough speed to stay on the track at the top.
