`P = W /( Deltat )`

Enter a value for all fields

The **Power Dissipated by Friction **compute the power dissipated by friction based on the work and time interval.

**INSTRUCTIONS**: Choose units and enter the following:

- (
**W**) This is the work - (
**Δt**) This is the change in time

**Power Dissipated by Friction (P): **The calculator returns the power in watts. However, this can be automatically converted to compatible units via the pull-down menu.

The **Power Dissipated by Friction** formula is

P=W/Δt

where:

- P = Power dissipated by friction
- W = work
- Δt = time interval

**Power**is a measurement of the energy used to move vehicles (automobiles, trucks, tractors, trains, boats and airplanes).**Power**is the measurement of energy consumed by a motor and transferred to the drive or wheels.**Power**is the amount of electrical energy consumed or produced by a system over time such as the energy produced by a hydroelectric dam or energy consumed by an electrical motor.

**Power **is most commonly measured in watts (W). One watt is equal to one joule per second (1 W = 1 J / 1 s). Power is also measured in horsepower (hp) where 1 horsepower equals 745.7 watts. Power is also measured in heat energy transfer as BTUs per hour (BTU/h).
