Transfer of energy and something else.
For work to be done, a force must be applied to an object, causing it to move in the direction of the force. Work is defined as force acting over a distance, so the object must be displaced by the force applied to it in order for work to be done.
In order for work to be done, a force must be applied to an object, causing the object to move, translating the force into displacement. Work is calculated as the force applied multiplied by the distance the object moves 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.)
In order for work to be done, two things must be present: force and displacement. Force is applied to an object to move it, causing it to undergo a displacement in the direction of the force. Work is calculated as the product of force and displacement in the direction of the force.

In order for work to be done, a force must be applied to an object, causing the object to move, translating the force into displacement. Work is calculated as the force applied multiplied by the distance the object moves in the direction of the force.

evaluate the things that somethng must move whenever work is done why is this requirement
work done to make new things
Work is done when a force is applied to an object and the object moves in the direction of the force. It is the transfer of energy from one form to another. The amount of work done is calculated as the force applied multiplied by the distance the object moves in the direction of the force.
1. A force is needed 2. The point of application of the force is to be displaced. 3. If the displacement is in the direction of the force then work is said to be done by the force and if the direction of displacement is opposite to the force then work is done against the force.

No. The ovum must be there for it to occur. This is why birth control pills work and tying the tubes work.
