Question

Is it possible that a body be In accelerated motion under a force acting on the body, yet no work is being done by the force ? give an example.

Answer 1

Hello friend,
Here's your answer:

Actually,

If a body is in accelerated motion, so obviously distance is covered.
Now as the force is applied, so acceleration is possible, It must have a mass. Matter has mass, Energy doesn't.
So we know that it is a matter.

So now 'Work' is a derived physical quantity.
Work depends upon the following factors:
1) Angle in which force is acting.
2) Force applied
3) distance covered.

So if distance is 0, Work is 0.
If a body is accelerating, then It must cover some distance because the velocity changes.
Therefore there is some work produced.

So it is not possible that a body be in accelerated motion under a force acting on the body, yet no work is being done by he force.


Hope my answer helps you.
