Practical tools for measured work
Work and force calculator
Solve Newton law, sum planar force vectors and calculate work at an angle.
Calculate the layout, check the diagram, then print the result for the shop or jobsite.
How it works
Newton’s second law is net force = mass × acceleration. Add forces by signed X and Y components before taking the magnitude. Constant-force work is Fd cos(θ), where θ is the angle to displacement. A 10 N force over 2 m at 60° does 10 J of work. In the diagram, blue arrows are inputs and the red arrow is their sum.

Before using the result
- Check the selected mode, units and input values before using the result.
- Read the assumptions and rounding rules; compare the worked example with your intended calculation.
- A numerical result does not supply missing context or change the stated limitations.
Limitations
Mass must be positive. Work mode accepts force and displacement magnitudes with angles from −180° to 180°. Vector mode accepts at most 32 planar forces. These models exclude variable-force integration and rotational dynamics.
