how are energy and work-related?

Answer 1

Very closelyEnergy is the ability to do work. Objects that have greater energy can do more work.

Click on Mechanics; then click on Work, Energy, and Power.

Additional AnswerWork (W) is done whenever one form of energy is changed into another form of energy. For example an electric motor does work by changing electrical energy into kinetic energy.

Work is very closely related to heat. Heat (Q) describes the transfer of energy from a warmer body to a cooler body.

For example when an electric kettle is switched on, electrical energy is converted into internal energy -so, work is being done. As the kettle's internal energy increases, its temperature increases above the surrounding temperature and, so, energy is transferred away from the kettle by heat.

So, the increase in energy of the kettle is the difference between the work done on the kettle and the heat lost from the kettle -i.e. W - Q = change of energy.

Answer 2

in the form of force
