Power from Force and Distance over Time

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:

Power = F•d/t

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).
