Question

What is the work done by the force of gravity on a satellite moving round the earth? Justify your answer.

Answer 1

work done by the satellite by moving around the earth is 0 .......

now u will ask.....y?

because if u ponder over it ......

you will conclude that the satellite moving around the earth is moving in the perpendicular form.....


and when the object makes an angle of 90° with other object then the wokr done by the object becomes 0

and it is in the terms of physics.....ok?

I hope you have understood it.....

plz mark as brainliest.....☺

Answer 2

➡Hey there !!
__________________

*Work done by gravity is Zero ..

◆Let see how this could be :-

We know that ◆ work done = F.S =
FScosx

now force of gravity acting on satellite is perpendicular to the direction of motion.

=> x = 90° or π/2

therefore , Work done = FScos90

=> cos90 = 0

so , work done = FS×0 = 0

Therefore work done by gravity on satellite is Zero(0) .
