Overview
Students should be able to calculate the Gravitational force between two masses. Calculate the gravitational force between two planets. Explain the meaning of 'G' and show that 'g' is the force per unit mass on the earth's surface. Relate Kepters laws to the motion of the solar system. Distinguish between Natural and artificial satellite Explain how artificial satellites are launched. Exp!ain the concept of escape velocity.
