The Work and Power Calculator is a versatile tool that allows you to compute work and power values effortlessly. But what exactly do these terms mean?
Work (W): A force applied to an object transfers energy, causing the object to move a certain distance in the direction of the force. The work formula is as follows:
Where:
- W represents the work done (measured in joules, J).
- F is the magnitude of the force applied (measured in newtons, N).
- d signifies the distance over which the force is applied (measured in meters, m).
- θ is the angle between the force vector and the direction of motion (measured in degrees).
It’s important to note that the cosine of the angle accounts for the fact that only the component of the force in the direction of motion contributes to the work.
Power (P): Power, on the other hand, is the rate at which work is done or the rate at which energy is transferred. The power formula is as follows:
Where:
- P represents the power (measured in watts, W).
- F is the magnitude of the force applied (measured in newtons, N).
- v denotes the velocity of the object (measured in meters per second, m/s).
Now that we have a basic understanding of these concepts, let’s explore how the Work and Power Calculator can simplify your calculations.

Example of Work and Power Calculator
Let’s walk through a practical example to illustrate how the Work and Power Calculator works. Imagine you’re lifting a 10-kilogram object with a force of 50 newtons at an angle of 30 degrees to the horizontal. You want to know the work done and the power exerted. Here’s how you can use the calculator:
- Enter the force: 50 N
- Enter the distance (height lifted): 2 m
- Enter the angle: 30 degrees
Click the “Calculate” button, and voila! The calculator will instantly provide you with the work done and power exerted. In this case, the work is approximately 86.60 J, and the power is approximately 43.30 W.
