What is power?
- The amount of energy transferred or converted per unit time is referred to as power. The watt is the unit of power in the International System of Units, equal to one joule per second. Power is sometimes referred to as activity in older works. A scalar quantity is power.
- The rate at which work is completed is referred to as power. Rate means per unit of time in this context. Power is calculated by dividing the amount of work done by the amount of time it took to complete the work.
Given,
Mass = 50kg
Distance = 0.3 meters
Time = 2 seconds
W = fd
P = W/(t₂ - t₁)
To find work
W = (50kg)(0.3m)
W = 15J
To find power.
P = 15J / 2 - 0
P = 15J / 2
P = 7.5 J/s
Therefor the power is 7.5J/s
