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.)

If a force of 100 newtons was exerted on an object and no work was done the object must have?
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!
What is required to work?
You must have an energy which moves an object. If the object does not move - No work is done.
What must occur in order for work to be done?
"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.
What 2 things must occur for work to be done?
Transfer of energy and something else.
What must be true when work is done?
an object moves in the same direction as a force exerted on it

What are three thing that must occur in order for work to be done?

What must happen to an object if a force does work on it?
Move a certain distance since Work Done=Fd
What must be true when work is done?
an object moves in the same direction as a force exerted on it
What occur in order for work to be done?
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.
When can you say that work is done on an object?
when a force acts to move an object,we say that work was done on the object
How can work be done?
Work done when force moves an object.
When is work not done on an object?
Work = Force x Distance. so no work is done if there is no force exerted, or if the object does not move.
How work done against gravitational force?
Lift any object. Grav. force is acting down, you must apply an upward force to lift the object. Work is force applied through a distance, so work is done if you lift it, but not if you hold it still.
