Identify all that apply. Satellites are falling projectiles. All satellites follow circular paths. The orbital velocity of a satellite does not depend upon the mass of the planet around which it orbits. By definition, a geosynchronous satellite orbits the earth in a perfect circle, maintaining the same distance above the surface of the earth.
Satellites travel faster along their orbital path when they are closest to the earth.
The acceleration of a satellite varies inversely with its distance from the center of the earth. More distant satellites have smaller accelerations. Identify all that apply. The force of gravity is the only force which acts upon the planets. Their trajectories are highly elliptical.
