Leaning tower video – gravity investigation with air resistance
This online resource is a short video about the gravity tower at Gingin near Perth.
The video, from the ABC television show Catalyst, 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.
