This online resource is a short video about the gravity tower at Gingin near Perth which was taken from the ABC television show Catalyst.

The video shows several objects being dropped from the 45 m high tower and their acceleration due to gravity is compared.

It also demonstrates that an object with a chain attached, like a bungee cord, can actually accelerate faster than gravity.

This is then compared to the cracking of a whip where the whipping motion accelerates the end of the whip to a speed faster than the speed of sound.
