Moment of Force Puzzles
Click on the buttons to reveal hints and answers!
1. Define the moment of force.
Hint: It's related to rotation and distance from the pivot.
Answer: Moment of force is the turning effect of a force about a point.
2. What is the SI unit of the moment of force?
Hint: It involves force and distance.
Answer: The SI unit is newton metre (N m).
3. State the relation between force and moment of force.
Hint: It's a product of two quantities.
Answer: Moment of force = Force × Perpendicular distance from the pivot.
4. Calculate the moment of force if a 10 N force is applied at a distance of 2 m from the pivot.
Hint: Use the formula: Moment = Force × Distance.
Answer: Moment = 10 × 2 = 20 N m.
5. What happens to the moment of force if the distance from the pivot is doubled?
Hint: Think about the direct proportionality.
Answer: The moment of force also doubles.
