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 Math / Science
The Power Dissipated by Friction formula is
P=W/Δt
where:
- P = Power dissipated by friction
- W = work
- Δt = time interval
Power is the amount of energy consumed or produced over time.
- 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 Units
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).
Power Calculators
- Power from Change in Energy over Time
- Power based on Force and Velocity
- P = ΔE / Δt
- ΔE = P * Δt
- Δt = ΔE / P
- Power Dissipated by Friction
- Power from Force, Distance and Time
- Power from Resistance and Current
- Power from Voltage and Resistance
