P5a: Satellites, Gravity and Circular Motion
Satellites have played a major part in the global communications revolution. We can call someone on the other side of the world using a mobile phone or watch events around the world, as they happen, in the comfort of our own homes. This item looks at what satellites are, their uses,including communications and satellite TV, and the physics behind what keeps them in the correct orbit. Newton’s experiment illustrates how uncertainties about science ideas change over time, and the use of models to explain phenomena.
