Orbital Motion

Orbital motions occur around an object that generates a centripetal force due to the effect of gravity. Is the net force acting on the satellite zero? Why doesn't it fall?

Orbital Motion II

The satellite orbits the Earth under the influence of gravity. Check the relationship between the radius of gyration and circular velocity.

Geostationary Orbit

A satellite in a geostationary orbit rotates synchronously with the Earth. The geostationary orbit is located at about 36,000 km altitude in the plane of the equator. Check what happens as the radius or circular velocity changes.

Gravity and Orbits

Move the sun, earth, moon and space station to see how it affects their gravitational forces and orbital paths. Visualize the sizes and distances between the different celestial bodies and turn off gravity to see what would happen without gravity!
