The word 'work' in physics is defined as the transfer of energy from one material body to another. It is a body's displacement in space caused by an external force resulting in motion. If a force is applied but there is no displacement or motion, then no work is done. Also work is not done if a force is applied perpendicular to the body's displacement. Work is expressed in units such as joules or foot-pounds.

In physics, work is defined as the energy transferred to or from an object by means of a force acting on the object as it moves in the direction of the force. Mathematically, work is calculated as the force applied to an object multiplied by the distance over which the force is applied.

What is the operational definition of work in physics?

In physics, work is defined as the transfer of energy that occurs when a force is applied to an object and the object moves in the direction of the force. Mathematically, work is calculated as the product of the force applied to an object and the displacement of the object in the direction of the force.


Where is work done?

If you mean "work" in the way it is used in physics, the basic definition of work is force x distance. In other words, if you apply a force over a certain distance, work is done.

What is the meaning physics?

Based on the etymology of the word, physics can be defined in the following way: "Physics is the episteme of Nature, and Nature (Φύσις) is the phenomenon of spontaneous appearance and evolution."
