Physics Study Guide
Concept
Work, energy and power
Exam focus
Use it after identifying the force, displacement and energy model. Work is signed; distinguish work by a force from the magnitude of energy transferred. In an exam, write the governing equation first, substitute values with units, and check the dimensions of the final quantity.
Common mistakes
- Do not mix units; convert all dimensional inputs to a consistent unit system before substitution.
- Check signs, directions, angles and reference points before entering values.
- Do not apply the formula outside its stated physical assumptions or boundary conditions.
How to verify your answer
Check the result against the displayed formula, expected unit and physical scale. For this calculator, also verify that the stated assumptions and limiting case are satisfied.
Model limits
This result is valid only under the assumptions stated on the calculator page. For real systems with non-ideal geometry, losses, distributed effects or relativistic/quantum corrections, use the appropriate advanced model.
