Work is defined as the application of a force over a distance. In other words, it is the energy transferred when a force is applied to an object and the object moves in the direction of the force.
Work and energy are closely related concepts. Work is the transfer of energy, and energy is the ability to do work. In other words, work is a measure of the change in an object's energy.
Power is the rate at which work is done or energy is transferred. It is defined as the amount of work done per unit time. In other words, power is a measure of how quickly energy is being transferred or work is being done.
The unit of measurement for work and energy is the joule (J), while the unit of measurement for power is the watt (W). One joule is equal to one watt-second, meaning one joule of work is done when one watt of power is applied for one second.
In real-world situations, work, energy, and power are all interconnected. Work is the energy transferred when a force is applied to an object, and power is the rate at which this energy is transferred. A higher power output means that work can be done faster, while a higher amount of work done means that more energy has been transferred.
