Work and Power Calculator

What Is a Work and Power Calculator?

The Work and Power Calculator solves the mechanical relationships between force, distance, work, power, and time. Work measures the energy transferred when a force moves an object, and power measures how quickly that energy is used. Pick what you want to find and the tool rearranges the formulas for you.

How the Calculation Works

Work is force times distance, and power is work divided by time:

$$W = F d$$

$$P = \frac{W}{t}$$

Where:

• W is work in joules (J)
• F is force in newtons (N)
• d is distance in meters (m)
• P is power in watts (W)
• t is time in seconds (s)

Reversing the equations gives F = W/d, d = W/F, and t = W/P, which the calculator applies when you select Force, Distance, or Time.

Worked Example

Pushing with 50 N over a distance of 10 m does:

$$W = 50 \times 10 = 500 \text{ J}$$

If that work takes 5 seconds, the average power is:

$$P = \frac{500}{5} = 100 \text{ W}$$
