Physics Work Calculator
Calculate mechanical work by a constant force over a straight displacement at a specified angle.
Formula
Work = force x displacement x cos(angle between force and displacement).
About the Physics Work Calculator
Calculate mechanical work by a constant force over a straight displacement at a specified angle.
How the Physics Work Calculator Works
The force component parallel to motion is found with cosine, then multiplied by signed displacement and converted from joules to kilojoules and foot-pounds.
Formula
Work = force x displacement x cos(angle between force and displacement).
The calculation runs in your browser. Values are validated for required ranges, compatible units, and method-specific restrictions before results are displayed.

Accuracy and Limitations
This applies to a constant force and straight displacement. Variable force, curved paths, friction components, and rotational work require integration or separate terms.
Keep units consistent, use measurements that represent the actual situation, retain full precision during the calculation, and round only the final answer. Professional decisions may require current official rules, field measurements, laboratory methods, or specialist review.
