Learn circular motion from start to finish with a clear and easy-to-follow explanation. This guide covers key concepts like ...

We solve for centripetal acceleration, centripetal force, and tangential velocity. In this Closer Look segment on circular motion, we investigate circular motion and solve for centripetal acceleration ...

Polar orbits take the satellites over the Earth's poles. The satellites travel very close to the Earth (as low as 200 km above sea level), so they must travel at very high speeds (nearly 8,000 m/s).
