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 object?
Experiences a displacement in the direction of the force.
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.
Is work done every time forces are exerted on an object?
No, work is only done if the force causes the object to move in the direction of the force. If the force is exerted but the object does not move, no work is done. Work is calculated as force multiplied by the distance the object moves in the direction of the force.
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.

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 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 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.
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)
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 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.
In the force has a component in the opposite direction from the motion the work done is negative?
Yes, when a force opposes the direction of an object's motion, the work done by that force is negative. This is because the force is doing work in the opposite direction of the displacement, resulting in a decrease in the object's energy.
How is work done in different situation?
Work is done when a force is applied to an object and the object moves in the same direction as the force. The formula for work is work = force x distance. Different situations involve variations in the amount of force applied, the distance over which the force is exerted, and whether the force is exerted parallel or perpendicular to the direction of motion.
