In a cyclic process something has to be moved in what we call a cycle, and movement needs energy to be provided in some way. For example the "rain water cycle" has the Sun as a heat source, causing evaporation to move water from the ground to the air. It then rises to form clouds, which, when big enough, cannot hold the water drops, so causing rain (or it may be fog or snow) which thus returns the water to the earth again.
Similarly the 4 stroke cycle of a car or motor bike engine would not be able to move the machine unless there was fuel to be burned inside the cylinders.

Why does work done is zero in isochoric process?
work done (by) the system equals zero , W=P(v2 - v1)= zero , where v2 = v1
Work done in a free expansion process is?
zero. because in free expansion volume of gas increase against any resistance.
Why is no work being done on books on shelf physics?
Work = force x distance. With a distance of zero, the work will also be zero.
When is workdone by force is zero?
work done on an object zero by a force would be zero isif the displacement of the object is zero
Why work done by centripetal force during half rotation 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 for which process?
In throttling process, work done is zero.
Why does work done is zero in isochoric process?
work done (by) the system equals zero , W=P(v2 - v1)= zero , where v2 = v1
How cyclic integral of a point function is zero?
the cyclic integral of this is zero
What is work done if there is nodisplacement is 0?
Work Done = Force x Displacement, so if the displacement is zero, the work done will be zero. There will be no work done.
What is PMM 1 why it is impossible?
WHAT IS PMM-1 A PMM1 is a Thermodynamic system that undergoes a cyclic process that produce no external affects other than the rise ( or fall) of a weight in a gravity field. WHY IS IT IMPOSSIBLE? PMM-1 state that work can still be produce in a cyclic process. This definition is against first law of thermodynamics and conservation of energy. According to first law of thermodynamics, in cyclic process E2- E1 = mg (h2 - h1) h2= h1 in cyclic process so the above equation yields E2=E1. where as according to PMM-1 you can produce work even when energy is zero (0), which makes it impossible
What is meant by zero work?
That means that no work is done.
Work done in a free expansion process is?
zero. because in free expansion volume of gas increase against any resistance.
When you ignite a matchstick then work will be done or not?
no work will be done because force is applied but displacement is zero so no work will be done.
When an object moves circular path what is the work done specify reason?
Zero work done
When is work done is zero?
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.

What is the difference between negative work and zero work and positive 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.
Why is no work being done on books on shelf physics?
Work = force x distance. With a distance of zero, the work will also be zero.
