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 a force is exerted on an object work is done only if the object?
Only if the object moves
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.
What must be true when work is done?
an object moves in the same direction as a force exerted on it
If a force of 90 Newtons was exerted on an object and no work was done would the object gain momentum?
it would remain motionless.
What happens when you exert force on an abject and it exerts force on you?
According to Newtons 3rd law, "Every action has an equal and opposite reaction". if you exert force on an object, the object will exert an equal and opposite force on you. when the forces exerted by you and the object balance a state of equilibrium is attained. however if you exert a force greater than the weight of the body, the body begins to move and work is done.
How can an object be put into motion naturally?
An object needs to have some sort of force exerted on it to be put into motion. There are no "unnatural" forces, therefore any object put into motion will have been done so "naturally."

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.

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!
If an odject is at rest all forces acting on that obkect is?
If an object is at rest 2 forces are still acting on it (if done on a planet) gravity pushing the object down. And the up force which is the force exerted by ground upwards against the object. Gravity being the greater force keeps the object on the ground, but the upforce prevents the object from basically ploughing through the ground.
What is the definition of work'?
Is done when a force exerted on an object causes that object to move some distance; equals to force times distance; measured in joules (j)
In the force has a component in the opposite direction from the motion the work done is negative?
No the work done is still positive, the force exerted and the work done to exert that force is still the same. Its just that the other object is exerting more of a force on the object doing the work.
What instrument measures how much work is being done to move an object?
A spring scale and a meter stick. Spring scale may be used to find force exerted. Meter stick finds distance through which force was exerted.
Do all forces of an object cause work to be done?
If a force is applied, but nothing in the system moves, no work has been done. Work is only done when something moves.
