The video tutorial explains how to calculate the speed of a satellite in a circular orbit above Earth. It derives the equation for satellite speed using centripetal and gravitational forces. The tutorial then calculates the speed and period of a satellite, and explains the concept of a geosynchronous satellite, including its period and height above Earth. The video concludes with a calculation of the satellite's speed and height using derived equations.
