Satellite Orbit Investigation Aim To investigate how the force of gravity on a satellite and the radius of the orbit affects the speed necessary to maintain the orbit of the satellite. Prediction When a satellite orbits round a planet it moves in a circular motion. An example of a satellite is the moon moving round the Earth. A satellites speed stays the same because speed = distance/time and it is always taking the same time to travel a certain distance. However its velocity changes because velocity is speed in a direction. Speed is a size but velocity is a size and a direction. As a satellite orbits a planet it changes direction constantly. If something is moving in a circular motion needs a force to change its direction constantly. This force is called a centripetal force. For a satellite moving round a planet this force is gravity. The direction of this force is towards...
