Final answer:
Power is the rate of doing work or transferring energy, measured in units of Joules per second or Watts. It signifies the amount of work done or energy transferred per unit of time.
Explanation:
Power is defined as the rate of doing work and is measured in units of Joules per second (J/s) or Watts (W). It represents the amount of work done or energy transferred per unit of time. For example, if you lift a heavy box to a shelf, the power you exert is the rate at which you are doing the work of lifting the box. Power can be calculated using the formula P = W/t, where P is power, W is work done, and t is time.
