Discuss how objects "fall" to the Earth when released from a high point with varying forces. Elicit the pathways taken from a straight line to a curved path. Determine the distance traveled in a given period of time for each pathway. From that information elicit the definition of a satellite. Discuss the rate at which an object falls and the rate at which the Earth curves. Determine distance for 1 second. Determine curvature of the Earth as a 5m drop every 8000 meters. Determine the velocity needed to orbit the planet.
