Physics
Work Calculator
Compute the mechanical work done when a force moves an object over a distance, optionally considering the angle between force and motion.

Mechanical Work
Estimate energy transfer when a force moves an object.

Work-energy principle
Work = Force × Distance × cos(θ)
Force and distance must be in compatible units. When no angle is provided the calculator assumes force and motion align (θ = 0).
How to use
- Enter the applied force and displacement distance.
- Add the angle between force and displacement if the push or pull is not aligned.
- Review total work in joules plus converted kilojoules and foot-pounds.
Example
Input: Force = 150 N, Distance = 12 m, Angle = 25°
Output: Work ≈ 1,629 J (≈ 1.63 kJ, ≈ 1,202 ft·lb)
FAQ & notes
What if the object doesn’t move?
Set the displacement to zero; the work output will also be zero because no energy transfers when distance is zero.
Can I enter negative angles?
Yes—negative angles reverse the cosine component so the work result reflects opposing force directions.
