Differentiate between work and power.

Open in App

Solution

Work
Power
1. Work is said to be done when a force causes a displacement in its direction. 1. The rate of doing work is called power.
2. Mathematically, $W o r k D o n e = F o r c e x D i s p l a c e m e n t$ 2. Mathematically, $P o w e r = \frac{w o r k d o n e}{t i m e}$
3. SI unit of work done is joule (J). 3. Now the SI unit of power is watt (W).
