Mechanical Power
In mechanical systems, the sum of forces and motion is known as power. Power is generally the product of a force acting on an object multiplied by its velocity, or the result of torque acting on a shaft multiplied by its angular velocity.
The time derivative of work is another way to define mechanical power. Hence, the mechanical power is given by.
Mechanical Power = Force × velocity
or
Pm = F × v
Power
Power in Physics is defined as the time rate of the amount of energy converted or transferred. In the SI system (or International System of Units), Watt (W) is the unit of Power. Watt is equal to one joule per second. In earlier studies, power is sometimes called Activity. Power is a scalar quantity. Power is a function of Work done, therefore if a person works at a variable rate depending on the time of day, his power will likewise vary.
