Answer 2

Answer: Energy:- Energy is equal to the force applied on displaced body. It's SI unit is Joule which is denote by 'j'

So, Energy = F×S

Power:- Power is equal to workdone(energy) per unit time taken.

It's SI unit is watt which is denoted by 'W'

So, Power = workdone(Energy)/time-taken

P=w/t
