Which of the following units is equivalent to the watt?
- A. kgms-2
- B. kgm2s-3
- C. kgm2s-2
- D. kgm2s-1
Correct Answer: B. kgm2s-3
Explanation
\(Power = \frac{\text{Work done}}{time}\)
= \(\frac{Force \times distance}{time}\)
= \(\frac{mass \times acceleration \times distance}{time}\)
= \(\frac{kg \times m \times m}{s^{2} \times s}\)
= \(kgm^{2} s^{-3}\)
