Activity 5

The following statements are similarities and differences between wedges and single inclined planes. Choose the appropriate underlined word to complete each sentence.

1. The input force is applied thickness/parallel/perpendicular to the ramp of an inclined plane, while the input force is applied thickness/parallel/perpendicular to the thickness/parallel/perpendicular of the wedge.

2. Inclined/split/Instead of helping you to move things to a higher level as inclined/split/instead planes do, normally wedges help you to inclined/split/instead things apart

   1. Although the wedge/both/machines is an adaptation of the inclined plane wedge/both/machines of them are simple wedge/both/machines.

   2. The mechanical advantage of inclined planes and wedges is the output/input/ratio of the output/input/ratio force to the output/input/ratio force.

   3. In both machines the bigger/angle/smaller the bigger/angle/smaller, the bigger/angle/smaller the mechanical advantage.

   4. In use/remains/moves, an inclined plane use/remains/moves stationary while the wedge use/remains/moves.

   5. Inclined force/energy/planes and wedges multiply force/energy/planes but they don’t multiply force/energy/planes.
