What is Hooke's law? - BBC Bitesize GCSE Physics

Our contestants must SPRING into action and answer correctly to win themselves a roadworthy prize, with the help of Dr Rula and the always-racing-ahead-with-the-ratings host of Extreme Physics, Isaac Neutron. And remember... if it ain't fun, it ain't physics!
