During its circular orbit, in a very small amount of time dt, Venus moves an infinitesimal amount ds. What is the work done on Venus by the gravitational force during that time? Recall that the work done by gravity is calculated as dWgrav ds. grav Hint: You might want to draw a diagram of Fgrav and ds. Will Venus' kinetic energy change as it moves along its circular orbit?
