Correct answer: Power.
Explanation:
- Power is the rate at which work is done (or energy is transferred).
- Average power: P = W / t (work divided by time).
- Instantaneous power: P = dW/dt; for a force acting on an object moving at velocity v, P = F · v.
- SI unit: watt (W) = joule per second (J/s).
Kinetic energy and work are energies (not rates); time is the interval over which work is done.
