When a force is exerted on an object causes the object to move then what is done on the object?
When a force is exerted on an object causing it to move, work is done on the object. Work is defined as force acting over a distance in the direction of the force.
When a force is exerted on an object work is done only if the objec?
moves in the direction of the force. If the object does not move in the direction of the force, then no work is done on the object.
When a force is exerted on an object work is done only if the object?
Experiences a displacement in the direction of the force.
If a force of 90 Newtons was exerted on an object and no work was done would the object gain momentum?
No, since work is required for an object to gain momentum. In this case, if no work was done (work=force x distance), then the object would not gain momentum despite the force being exerted on it.
What is an example in which a force is exerted on an object without doing work on the object?
Pushing against a stationary wall is an example where a force is exerted on the wall, but no work is done on the wall since it does not move. Work is only done when a force causes an object to move over a distance in the direction of the force.
When a force is exerted on an object causes the object to move then what is done on the object?
When a force is exerted on an object causing it to move, work is done on the object. Work is defined as force acting over a distance in the direction of the force.
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 a force is exerted on an object work is done only if the objec?
moves in the direction of the force. If the object does not move in the direction of the force, then no work is done on the object.

When is work not done on an object?
Work is not done on an object when there is no displacement of the object in the direction of the force applied. In other words, if the force and the displacement are perpendicular to each other, no work is done. Additionally, if there is no force acting on an object, no work is being done on it.
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 happens when work is done on an object?
When work is done on an object, energy is transferred to the object, causing it to move or change its position. The amount of work done is equal to the force applied to the object multiplied by the distance over which the force is exerted. This work can result in the object gaining kinetic energy, potential energy, or both.
What must be true when work is done?
When work is done, there must be a force acting on an object, and the object must move in the direction of the force. The amount of work done is calculated by multiplying the force applied by the distance 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?
If no work was done, the object must not have moved in the direction of the force. This could happen if the force was applied perpendicular to the object's motion or if the object remained stationary.
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)
