About the Work, Energy & Power Calculator

Work, Energy & Power is treated here as a quantitative relation between Force, Distance, Time and Work and Work, Power, Power and Force.

The calculator uses a multi formula configuration. Each reported value is read as a direct evaluation of the stored rules with the declared field formats and units.

Formula basis:
W = F x d (Work in Joules = Force in Newtons x Distance in meters)
P = W / t (Power in Watts = Work in Joules / Time in seconds)
P (hp) = P (W) / 745.7
F = W / d (Force = Work / Distance)
d = W / F (Distance = Work / Force)

Interpret the outputs in the order shown by the result fields. Optional inputs affect only the outputs that depend on those variables.

Formula & How It Works

The calculation applies the following relations exactly as recorded in the metadata:

W = F x d (Work in Joules = Force in Newtons x Distance in meters)
P = W / t (Power in Watts = Work in Joules / Time in seconds)
P (hp) = P (W) / 745.7
F = W / d (Force = Work / Distance)
d = W / F (Distance = Work / Force)

Each output field is produced by substituting the supplied inputs into the relevant relation and then applying the declared rounding or text format.

Worked Examples

Example 1: Moving Furniture — Amateur Mover

Inputs

force: 200 distance: 15 time: 10
Work: 3,000 J. Power: 300 W. Power: 0.4023 hp

With Force = 200, Distance = 15 and Time = 10 as the stated inputs, the result is Work = 3,000 J, Power = 300 W and Power = 0.4023 hp. Each value corresponds to the declared output fields.

Example 2: Car Engine — Highway Cruising

Inputs

force: 1112 distance: 1609 time: 60
Work: 1,789,208 J. Power: 29,820.13 W. Power: 39.9895 hp

With Force = 1,112, Distance = 1,609 and Time = 60 as the stated inputs, the result is Work = 1,789,208 J, Power = 29,820.13 W and Power = 39.9895 hp. Each value corresponds to the declared output fields.

Example 3: Stair Climbing — Calorie Estimate

Inputs

force: 784 distance: 30.5 time: 120
Work: 23,912 J. Power: 199.27 W. Power: 0.2672 hp

With Force = 784, Distance = 30.5 and Time = 120 as the stated inputs, the result is Work = 23,912 J, Power = 199.27 W and Power = 0.2672 hp. Each value corresponds to the declared output fields.

Example 4: Electric Motor — Industrial Conveyor

Inputs

force: 4500 work: 45000
Work: 45,000 J. Distance: 10 m

With Force = 4,500 and Work = 45,000 as the stated inputs, the result is Work = 45,000 J and Distance = 10 m. Each value corresponds to the declared output fields.
