D1 activity: Satellites and escape speed

In this activity you will apply your knowledge of circular motion and gravity to derive an equation for a circular orbit and, in turn, an equation for the total energy of an orbiting body. You should be able to sketch graphs of kinetic energy, potential energy and total energy for orbiting bodies. Different Earth satellites have different orbit radii - you'll find out why - and you'll also find out the equation for...
