Gravitational potential energy

Vedclass · Answer

(B) The gravitational potential energy $(U)$ of a satellite of mass $m$ at a distance $r$ from the center of the Earth is given by $U = -\frac{GMm}{r}$,where $G$ is the gravitational constant and $M$ is the mass of the Earth.As the satellite moves to a further stable circular orbit,the orbital radius $r$ increases.Since $U = -\frac{GMm}{r}$,as $r$ increases,the magnitude of the negative value decreases,which means the value of $U$ increases (becomes less negative).Therefore,the gravitational potential energy increases.

An earth satellite is moved from one stable circular orbit to a further stable circular orbit. Which one of the following quantities increases?
