Question

Is it possible that no transfer of energy takes place even when a force is applied to a body?

Answer 1

Answer:

Yes. Forces are constantly applied to objects; for an energy transfer (work) to occur, there must be a force AND movement: work = force times distance.

Answer 2

Answer:Yes

Explanation:

Firstly whenever there is transfer of energy there will be work done

Ok

So we can say that is it possible that no work done when a force is applied

When the force and displacement direction is normal to each other

As we known W=f×d cos(theta)

cos 90 =0

Let

force =f and displacement =d

When we multiply them to get work

I.e W=f×d×cos 90 we get W=0(since cos 90=0)

Which mean no work is done even if force is applied

Example:- moon revolve around the earth

There is no transfer of energy or no work done but even the force is applied on moon (I.e gravitational force )
