work = force . distance.
Since Force and distance are both vectors (work is the dot product), when the net distance = 0 (back to the point of origin), work = 0. That is, if the force is such that it moves the object back to the point of origin, it has done zero work.
A centripetal force is one example. The distance = 0 when the object finishes one complete revolution. No work has been done since the beginning of the revolution.

What is an example of work in physics?
An example of work in physics is when a force is applied to an object, causing it to be displaced in the direction of the force. Work is calculated as the force applied multiplied by the distance over which the force is applied. Work is a transfer of energy and is measured in joules.
What is performed when a force moves an object through a distance?
Work is performed when a force moves an object through a distance. Work is calculated by multiplying the force applied by the distance over which the object moves in the direction of the force. The unit for work is the joule (J).
When an object moves work has occurred true or false?
True. Work is done when an object moves in the direction of the force applied to it. Work is calculated as the force applied multiplied by the distance the object moves in the direction of the force.
What is done when an object moves a distance because of a force?
When an object moves a distance due to a force acting on it, work is done on the object. Work is the transfer of energy to or from an object resulting in a change in its motion. Work is calculated by multiplying the force applied to the object by the distance the object moves in the direction of the force.
What is something done when a force moves an object over a distance?
Work is something that is done when a force moves an object over a distance.
Where do you say that work is done an object?
Work is done on an object when a force is applied to the object and the object moves in the direction of the force. The work done is calculated as the product of the force applied and the distance the object moves in the direction of the force.
Work is done when only what is applied?
Work is done when a force is applied to an object and the object moves in the direction of the force. It is calculated by multiplying the force applied by the distance the object moves in the direction of the force. If there is no movement, then no work is done.
What is an example of dynamic?
An external force that moves or changes
How can work be done?
Work done when force moves an object.
How is work defined in the context of physics?
In physics, work is defined as the transfer of energy that occurs when a force is applied to an object and it moves in the direction of the force. Work is calculated by multiplying the force applied to an object by the distance it moves in the direction of the force.
When a force moves an object over a distance?
Work is being done on the object. Work is equal to the force applied multiplied by the distance the object moves in the direction of the force. The work done causes a change in the object's energy.
What happens when a force moves an object over a distance?
Work
