Forces, Torque and Gears
- Force makes it move (from rest)
- 4.5 Newton = 1 lb
- Translational force
- Rotational :torque - makes it rotate. T=rxF
Where you apply the force, not just the force.
- Examples: opening the door; changing a flat tire.
- How things rotate. Regular records (turntable).
Two bugs on it.
Rotate at the same angular speed. Bu closer bug moves slower.
- Gears. Explain what each does in
