   What does power mean in physics?

   • machines … Power is the rate at which work is done or the rate at which energy is transfered from one place to another or transformed from one type to another. The symbol for power is an italicized, uppercase P. The bar (or overline) above the symbol for power in this equation indicates that the value computed would be an average power.

   What does power mean in science & engineering?

   • Power, in science and engineering, time rate of doing work or delivering energy, expressible as the amount of work done W, or energy transferred, divided by the time interval t—or W/t. A given amount of work can be done by a low-powered motor in a long time or by a high-powered motor in a short

   What is the unit of power?

   • We can define power as the rate of doing work, it is the work done in unit time. The SI unit of power is Watt (W) which is joules per second (J/s). Sometimes the power of motor vehicles and other machines is given in terms of Horsepower (hp), which is approximately equal to 745.7 watts. What is Average Power?

   Power in mechanical systems is the combination of forces and movement. In particular, power is the product of a force on an object and the object's velocity, or the product of a torque on a shaft and the shaft's angular velocity. Mechanical power is also described as the time derivative of work.
