Transfer of energy and something else.
A force must act on a body which, as a result undergoes motion in the direction of the force.
In order for work to be done there must be a Force F pushing over a distance D. Work=Force x Distance Work only is done in the direction of the Force.
"Work is done on an object if two things happen: (1) the object moves as a force is applied and (2) the direction of the object's motion is the same as the direction of the force.".SOURCES:Dumas, Leila, and William G. Lamb, Ph.D. "Chapter 1, Section 1: Work and Power." Holt Science & Technology: Forces, Motion, and Energy. Austin: Holt, Rinehart and Winston, 2005. 95. Print.
Formally, energy is required to do work. Work is technically force times distance. Thus, what must occur is a force must be applied to an object and the object must move with some movement being in the direction of the force. The quantity of work done is the "dot" product of the force vector and displacement vector. To carry out work "on an object" or in any fashion requires the same amount of energy be used as the amount of work done. (Of course, friction and other inefficiencies result in the use of more energy than the actual work done, with the excess energy taking some other form, such as heat.)
The object must be stationary. Work done happens when the object is moving in the direction of the force- if it is staying still, there is no work done!

evaluate the things that somethng must move whenever work is done why is this requirement
work done to make new things
No. The ovum must be there for it to occur. This is why birth control pills work and tying the tubes work.
work done to make new thigs
Work to be done "scientifically" the product of Force and Displacement (FD) must be other than zero.
The object must be stationary. Work done happens when the object is moving in the direction of the force- if it is staying still, there is no work done!
You must have an energy which moves an object. If the object does not move - No work is done.
