What are the characteristics of a lower satellite orbit?

Low polar


Strong gravitational attraction


Large centripetal acceleration


100 km above earth


2 hour orbit


Orbits above poles

Higher up satellite

Geostationary satellite


Longer orbital period - 24 hours


Weak gravitational attraction


Smaller centripetal force


Orbits at a fixed point above equator


36000 km above earth

What causes a planet to move in orbit and what's it called?

Circular motion


Centripetal force and tangential force combined cause the resultant. If gravitational increases so must centripetal
