What the work calculator solves
Use this work calculator when a constant force moves an object in the direction of the displacement.
Formula
How to use it
- Choose the quantity you want to solve for.
- Enter the known values with consistent units.
- Check the rearranged formula, substitution, and warnings before using the result.
How to read the answer
Work is energy transferred by force over distance. In this simple version, force and displacement point the same direction.
Common mistakes and edge cases
- If force is at an angle, multiply by cos(theta).
- Use meters for joules.
- Zero displacement means zero work in this model.

Frequently asked questions
Can the work calculator solve for a missing variable?+
Yes. Use the solve-for control to hide the missing value, then enter the other known values with compatible units.
Why do the units matter?+
Formula calculators assume the entered values are already in matching units. Convert first when your measurements use mixed systems.
