This online resource investigates the gravity tower at Gingin near Perth.
The resource is a video from the ABC television show Catalyst and 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.
