alleryThe SI unit of work is the:
ANewton (N)
BPascal (Pa)
CWatt (W)
DJoule (J)
Answer & Solution
Correct answer: D. Joule (J)
Work = Force × displacement, so its unit is N × m = joule (J).
We have 1 J = 1 N × 1 m.
So 1 J = 1 kg·m²·s⁻².
Watt is the unit of power, newton of force, pascal of pressure.
