Power (Physics) Calculator
Power from Work & Time
Power from Force & Velocity
Formula
P = W/t or P = Fv, where P is power in watts, W is work in joules, t is time in seconds, F is force in newtons, and v is velocity in m/s.
Frequently Asked Questions
What is power in physics?
Power is the rate at which work is done or energy is transferred. It is measured in watts (W), where 1 watt equals 1 joule per second.
What is the difference between power and energy?
Energy is the total amount of work that can be done, measured in joules. Power is how quickly that energy is used or transferred, measured in watts (joules per second).
