Work done is zero when force acts right angle to the direction of the motion of the body .
my situation of zero work done , one day i hold many books approximately 15 after some time i feel very tired but there is a physical work done is zero because i worked against right angle .
i feel actual work is done because when i holding book my muscles and blood circulate all over the body so i feel work is done.

If work is done on the system then it has a negative sign. If work is done by the system then it has a positive sign.
Anything multiplied by zero is is zero. So, this would also work for this particular equation. 8 multiplied by 0 is o.
There was 12k Joules of work done.
It´s a system that forces to zero values smaller than a given value. This is done in order to avoid measure or report very small values seen as noises.
Positive.
In throttling process, work done is zero.
Work Done = Force x Displacement, so if the displacement is zero, the work done will be zero. There will be no work done.
work done (by) the system equals zero , W=P(v2 - v1)= zero , where v2 = v1
That means that no work is done.
no work will be done because force is applied but displacement is zero so no work will be done.
Zero work done
If the angle between the displacement and force applied is less than a right angle, then it is Positive Work done. If the angle between the displacement and the force applied is greater than a right angle then it is Negative Work done. If the displacement and force are at right angles, or either is zero, then it is Zero Work done.
Work = force x distance. With a distance of zero, the work will also be zero.
work done on an object zero by a force would be zero isif the displacement of the object is zero
work done is zero because force is toward the centre and distance is tangent to the circle so cos90 is equal to zero.[abbasia]
work done is zero when gas expands in vacuum.sarin madhusoodanan
