the rate of work done is called power. power is a scalar quantity. power = work done / time. it's SI unit is joule / second is called watt.
☯ ANSWER:-
#POWER-
*The rate of doing work is called as power.
*It is also defined as the rate of transfer of energy.
*Power measures the speed of work done, that is, how fast or slow a work is done.
*Power= Work/Time or P= W/T which is J/s.
*The unit of power is "Watt".
* P= W/t
=> P= F×s/t
=>P= F × v
*We express larger rates of energy transfer in kilowatts (kW).
#Applications of power in our daily life:-
* Mechanical power:- Such as cars, engines, train engines, jet planes, etc.
*Electric power- All electrical appliances such as elevator motors, electric car engines, power lines, etc.
*Power of light sources (visible and non-visible):- Household lightbulbs, x-ray machines, gamma-ray guns, radio transmitters, etc.
*Thermal power- Steam engines and turbine rotators, etc.
*Atomic power- Polaris subs, atomic electric power plants, atomic bombs.
