Define work in physics.

Work in physics means the transfer of energy that happens when a force moves an object through a distance. The amount of work depends on how much force is applied and how far the object travels in the direction of that force, so you calculate it as W = F × d. The units come out as joules. If the force isn’t exactly in the direction of the motion, you use W = F d cos(theta) to reflect only the part of the force that acts along the displacement. The other statements aren’t correct definitions: work isn’t a form of stored energy in an object, it’s the transfer of energy; it isn’t the rate of energy transfer (that’s power); and it isn’t limited to energy becoming light, which would be a specific energy transformation rather than the general idea of work.
