If force is expressed in Newtons and distance in meters, then work done will be expressed in—
- AJoules
- BKgwt (kilogram weight)
- CKg wt m (kgwtm)
- DWatts
- ENone of the above/More than one of the above
Show answer and explanation
Correct answer: (a) Joules
Explanation
Work = force × distance moved in the direction of the force. With force in newtons and distance in metres, work is in newton-metres, called joules (J).
The kilogram-weight is a unit of force, and the watt is a unit of power.
