| S. No. | Inclined plane | Screw |
|---|---|---|
| 1. | An inclined plane is a slanting surface which connects two points at different heights. | A screw is an inclined plane wound around a rod spirally making a number of turns on it. |
| 2. | An inclined plane reduces the effort needed to lift objects. | It is commonly used for holding things together and lifting materials. |
| 3. | The mechanical advantage of an inclined plane is equal to the ratio of the length of the inclined plane to its vertical height such that longer length and shorter height provide more advantage. | The mechanical advantage of the screw is determined by its lead such that, smaller the lead, the higher is the mechanical advantage. |
| 4. | Example : children's slide and ramp for wheelchair. | Example : screws and bottles. |
