The Power from Force and Distance over Time calculator computes the power based on the Force (F), distance (d) and the time (t).
INSTRUCTIONS: Choose units and enter the following:
- (F) Force
- (d) Distance (over which force is applied)
- (t) Time (duration of travel)
Power (P): The calculator returns the power in watts (W). However, this can be automatically converted to compatible units via the pull-down menu..
The Math / Science
Power is the rate of doing work (w = F•d) over a period of time. It is equivalent to an amount of energy consumed per unit time. In the MKS system, the unit of power is the joule per second (J/s)
Power can be calculated as:-
- Power = Work/time
This calculator expands work to w = F•d to create the formula:
where:
- P = power
- F = constant force applied during the travel
- d = distance traveled
- t = duration of travel
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).
