Exam Science Law Of Levers Junior6 Part1

The law of levers states that ……….(choose)

The values ​​of effort and resistance in the lever depend on………(choose)

The distance between the effort force and fulcrum is……….(choose)

The distance between the resistance force and fulcrum is ………. (choose)

When the arm of force is longer than the arm of resistance, the effort force is (choose)…… the resistance.

When the arm of force………… the arm of resistance, the effort force equals the resistance force.

When the arm of force……….the arm of resistance, the lever doesn’t conserve effort

When the arm of force equals 4 cm. and the arm of resistance equals 4 cm. , SO ……… (choose)

The lever doesn’t save effort when …………. (Choose)

The effort force and resistance force are measured in………(Choose)

Force arm is sometimes equal to resistance arm in(Choose)………. class levers.

The type of levers which sometimes has a mechanical benefit is the ………(Choose)

The type of levers which always doesn’t save effort is the …………(Choose)

The type of levers which always has a mechanical benefit is the………..(Choose)

When the effort arm equals 5 cm. and the resistance arm equals 10 cm. , SO ………. (Choose)

Which of the following levers saves effort? ………..(Choose)

When the length of the force arm equals 2.5 meters and the length of the resistance arm equals 1.5 meters, so (Choose)……..

Which of the following levers doesn’t save effort?…………. (Choose)

Which of the following levers has the arm of force longer than the arm of resistance?…………. (choose)

All the following levers don’t save effort except………..(choose)
