What two things need to happen for there to be work done on an object?
If he object moves as a force is applied and the direction of the objects motion is the same as the direction of the same force.
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!
When work is done on a object the object gains energy?
yes.
What must happen to an object if a force does work on it?
Move a certain distance since Work Done=Fd
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.
Does an object have to move in order for work to be done?
Work = force x distance. If distance = 0, work = 0 because force x 0 = 0.

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 the scalar product of the force action on an object and the displacement caused by that force?
Work is the scalar product of the force acting on an object and the displacement caused by that force. In order for work to be done, the object must be moved in the direction of the force.
When work is done on a object the object gains energy?
yes.
Work is done when a force is applied to an object if the object .?
is moved
Whenever work is done on an object the object is given what?
Energy!
