How do we know if work is done?
In physics, work is done by a force acting on an object if the object moves in the direction of the force.
What is present when work is done?
In physics work is dome when a force acts on a body and the body moves in the direction of the force.
What is the definition of work done?
Physics definition of work: (force applied ) multiplied by (distance through which the force acts).
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.
What is an example of the physics definition of power?
Power is the rate of work done or rate of energy generated or expended

Is there such a proverb such as 'No work is done when something remains same'?
This statement can be applied to physics, so it could be considered a 'physics proverb'... Work equals force times distance, so no matter how much force is applied, if the object does not move, no work is done.
What is the definition of work done?
Physics definition of work: (force applied ) multiplied by (distance through which the force acts).
Where is work done?
If you mean "work" in the way it is used in physics, the basic definition of work is force x distance. In other words, if you apply a force over a certain distance, work is 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.
How much work is done when a donkey is carrying a load on it's back?
physics - no physically - yes
Does work reflect energy?
Yes, the amount of work a "machine" (in the physics sense) can get done is an indicator of how much energy the body possess.
What is an example of the physics definition of power?
Power is the rate of work done or rate of energy generated or expended
If a weight lifter lifts a barbell and then sets it down is any work done?
Answer: It depends upon your definition of "work". Assuming the lifter put the barbell back exactly where and how it was at first, then there was no work done in the physics context. If you mean manual labor, then yes, some work was done.
What is the work done by carrying force on the back pack?
WORK in terms of Physics is only done when there is motion of an Object. So even though you may tire while standing still wearing a Pack, NO WORK is being performed on the Pack itself (in terms of Physics). Once you start walking, then there is work being done MOVING the pack forward, as well as UP and DOWN! To find the total work done on the Pack, you would have to use Vector representation of the Forces and the Motion to solve the entire System's Work Performed.
Is it true that energy is transferred when work is done?
Yes, in physics, work is the amount of energy transferred when work is done by a force. If you put energy into a product, you do work on the product. In other words, work done is another way of saying energy transferred.ΔE = W, where Δ is the change in energy and W is work.
