If a force is applied, but nothing in the system moves, no work has been done. Work is only done when something moves.

How can the same amount of work be done if the forces acting on the object are different?
It depends on the distance over which the work is done. Work = Force x distance
Is work done every time forces are exerted on an object?
No. Only when there is also movement. The basic formula for work is: work = force x distance If a certain force is applied along a certain distance, then work is done.
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 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.
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!
How can the same amount of work be done if the forces acting on the object are different?
It depends on the distance over which the work is done. Work = Force x distance
How much work is done by the surface molecules pushing upward on the object when it moved horizontally?
If there is no vertical motion, then no work is done by any vertical forces.
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
Is work done every time forces are exerted on an 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.

When work is done on a object the object gains energy?
yes.
Whenever work is done on an object the object is given what?
Energy!
Work is done when a force is applied to an object if the object .?
is moved
When work is done an object?
move
