📚 Key Facts About Work Done
Work done = Energy transferred
- Unit: Joules (J) — same as energy!
- 1 Joule = 1 Newton × 1 metre (1 J = 1 Nm)
- Work is done BY a force ON an object
Important conditions:
- Force must cause movement
- Distance must be in the direction of the force
- No movement = no work done
- Force perpendicular to movement = no work done
