Question

Why is no energy being consumed in planetary motion?

Answer 1

Explanation:

No energy is consumed in the planetary motion because in planetary motion work done by the planet in moving the circular motion is zero. As we have W = F.S cosθ angle between the force and displacement is 90° which means W = 0. 6

Answer 2

Answer:

No, energy is being consumed in the planetary motion, the work done by the planet while moving in the circular motion is zero, so the work done by the force is zero.

Explanation:

The work done by the planetary motion is zero, because on the satellite the force of the gravity does not works.
