Satellite motion
Lesson Outline
Reviewing the acceleration due to gravity and the formula for determining the distance a projectile would fall in a given time led to a demonstration of the path taken by a projectile when released at varying velocities. The amount of curve of the Earth was given as 5Km every 8000 meters, and the velocity needed to produce a circular orbiting projectile was found to be 8km/s. At that speed, the satellite would fall toward the Earth's curvature and not hit the planet. A thought problem was presented as to why a satellite must be at least 150 km above the surface in order to remain in orbit. A discussion of the make-up of the atmosphere, of air resistance and the production of heat due to air friction was arrived at, and the answer to the problem determined to be related to the satellite needing to orbit above the atmosphere of the Earth so as to not become "burnt bacon".
