📚 What is a Moment?
What is a moment?
- A moment is the turning effect of a force
- Unit: Newton metres (Nm)
- Also called torque
- Moments cause objects to rotate around a pivot (fulcrum)
The distance matters:
- Distance must be measured perpendicular (at right angles) to the force
- Greater distance from pivot = greater moment = easier to turn
- This is why door handles are far from hinges!
