A satellite orbits around the Earth.Which statement below is true? K = kinetic energy of the satellite
U = gravitational potential energy of the satellite

Question

Quizplus · Accepted Answer

The kinetic energy (K) of a satellite in orbit is always greater than zero because it is moving. The gravitational potential energy (U) is considered negative because it is a bound system where work would need to be done (energy added) to remove the satellite from Earth's gravitational influence to infinity.
