Definition of Work:
The amount of energy that needs to be supplied to move by a certain distance of an object is work.
It is calculated as force multiplied by the displacement an object travels.
It is measured in joules (J), expressed as kg·m²/s² in SI units, or kilowatt-hours (kWh).
Definition of Power:
Power is the rate of change of work or the amount of work done in a certain amount of time. The higher the power of a
device, the more work it can perform in a given time period. It is measured in watts (W), equivalent to kg·m²/s³ in SI units.
P=W/t
