P3 1.8 SATELLITES
Imagine launching a satellite from a very tall mountain:
Moving in circles needs:1. high sideways speed 2. central force

P3 1.8 SATELLITES
Imagine launching a satellite from a very tall mountain:
Moving in circles needs:1. high sideways speed 2. central force
The period of an orbit is the time taken to make one complete orbit.
