Give an example when the force is being applied on the body but the work done is zero?

Answer 1

Work is force applied over a distance. So applying less force than is required to move the object.

Answer 2

Work done is also equal to change in energy.

Work can be zero when there is a force. The centripetal force in a uniform circular motion, for example, does zero work because the kinetic energy of the moving object doesn't change.

Answer 3

Sitting. Forces are gravity, and the normal force from the chair. You're not moving, so work is zero.

Any other activity on earth with zero displacement that involves any force involves no work. The examples are endless.

Answer 4

Work is force multiplied by the distance the object that the force is being applied to moves. Push on a brick wall - it doesn't move. No work is done.

Answer 5

WD = F/d
P=F/A
so i guess atmospheric pressure or pressure exerted by water acting on an object in a water tank although tecnically the work is being done by the gravitational pull of the earth

Answer 6

There are any number of scenarios where you could apply a force (in the macro world) and accomplish no work.
On the quantum scale, there is no static structure that would fit your question. Perhaps if you gave us more insight into the context of your question, we could better answer it?

Answer 7

work=force*displacement
or more specifically
w=fdcos@
therefore when displacement is perpendicular to the applied force work done is zero since cos90=0

Answer 8

a man carrying a porter with a suitcase on his head and climbing the steps. in this case work done by him is zero..

Answer 9

A car with soft tyres and you're alone and want to move it.
No matter how hard you push, it doesn't move !! ... that is the application of force with no APPARENT work done.
(However, your muscles tell you that you've been working).
