A satellite revolves around Earth in a circular orbit . what is the work done by the satellite. With step by step.
Answers
Answer:
Explanation:
Here the displacement of the satellite after one revolution is zero, which causes the work done by the satellite is zero. Thus, the work done by the satellite revolving around the earth in a circular path is calculated to be zero.

Explanation:
Work done is the dot product of force on the satellite and displacement of the satellite,
W

Here,
F
g
is the gravitational force of earth which is the only force applied on the satellite,
S
is displacement of the satellite and
θ
is the angle between the force and displacement.
The displacement at any point on the circular path is perpendicular to gravitational force of earth.
