To work out the power generated by a force, the magnitude of the force must be known. What other quantity is needed to work out the power?
- AThe distance that the force moves the object is needed and the time for which the force acts on the object is needed.
- BThe distance that the force moves the object is needed but the time for which the force acts on the object is not needed.
- CThe distance that the force moves the object is not needed but the time for which the force acts on the object is needed.
- DNeither the distance that the force moves the object nor the time for which the force acts on the object is needed.
