the-BA : Loop-the-loop

One of the most exhilarating parts of a roller coaster ride is the ‘loop-the-loop’. The roller coaster needs to build up enough speed to complete the loop. As the roller coaster moves around the loop, the passengers are forced into their seats, preventing them from falling out. When roller coaster ride designers are building a ride they need to work out how to build up enough speed to complete the loop.

Have you ever wondered how a roller coaster completes a loop?

You might like to …

• investigate how the speed of a toy car affects its ability to do a ‘loop-the-loop’
• investigate how the size of the ‘loop-the-loop’ affects the ability of a toy car to stay on the track
• make a working model of a rollercoaster ‘loop-the-loop’ that can be used in a demonstration about fairground physics.
