Torque and rotation
Apply a tangential force at different distances from a pivot and spin the disc.
What to notice
The same force produces more torque when you apply it farther from the axis.
Key relation
τ = rF = Iα
Try this
Keep the force fixed and double the lever arm.
What you can change
- Tangential force: 2 to 20 N
- Lever arm: 0.3 to 1.5 m
- Moment of inertia: 1 to 8 kg·m²
