Conclusion
| Type | Force | Distance | Features |
|---|---|---|---|
| Fixed Pulley | No saving (F≈G) | s = h | Changes direction |
| Movable Pulley | Saves 1/2 (F≈G/2) | Costs 2x (s=2h) | Saves force, direction same |
| Pulley System | Saves (F≈G/n) | Costs (s=nh) | Saves force & changes direction |
Note:Efficiency: η = W_useful/W_total = Gh/Fs < 100% (due to friction & pulley weight)
