power is a measure of?

Answer 1

power is a measure of the rate at which work is performed.

Answer 2

The other guys are oversimplifying this!

The TRUE definition is that power is the rate of change of energy with respect to time - which is not exactly the same as the amount of energy per unit time.

You have to take the derivative of energy to get power. Some of these other answeres are suggesting you can just take the energy and divide it by the time. That only works in special cases (periodic steady-state).

Answer 3

Power is a measure of energy

Answer 4

A good analogy would be to compare power to Acceleration. Just as acceleration is the rate of speed change in unit time, power is the rate of energy change per unit time. Energy changed means to transfer it from one form to another since energy cannot be created or destroyed.

Answer 5

Power is the rate at which work is done, expressed as the amount of work per unit time and commonly measured in units such as the watt and horsepower.

Answer 6

ability to do work. It is measured in perpendicular distance multiplied by force (foot-pounds). Doing work takes energy so it is also a measurement of energy.

Answer 7

power is work done per unit time, or how fast energy is converted frm on form to another..its given by Watts as its SI unit and is the multiplication of force x dist in dir of force (volt x current) / time if its electricity sense.. it can also be given as kwh to "compress" the unit when measuring large numbers...........=)

Answer 8

Respect

Answer 9

Watt (power) = Joules (energy) per second

Answer 10

Influence.
