KS2 (key stage 2) Online Quizzes on Levers

(Fascinating and Engaging KS2 revision quizzes on levers for children in year3, year4, year5 and even year6 of the ks2 level who wish to boost their knowledge and the performance in class)

What is a lever? There’s a high probability that you use levers everyday but you don’t even know that they are levers. A lever is a device that is used to do work faster and more efficiently. Levers are made up of a strong beam and a pivot (or fulcrum), An input force otherwise known as the effort and the output force otherwise known as the load are applied to either ends of the rigid beam. The pivot is the point on which the beam lies. When an input force is applied to one end of the leve, the output force is applied at the other end. This can cause a mass to move upward

There are basically three classes of levers and these classes are based on the position of the load, the effort and the pivot. We have the 1st, 2nd and 3rd class levers

1st class levers: They are levers which have their pivot between the effort and the load. Example, pliers, crow bar, claw hammer, scissors, see-saw etc

2nd class levers: Here, the load is between the fulcrum and the effort. Example, nutcrackers, wheelbarrow etc

3rd class lever: Third class levers are levers where the effort is between the load and the pivot. Example: a broom, a fishing rod etc.

The above explanation covers the basics of levers as seen in KS2, if you wish to revise about levers we will encourage you to try our sets of quizzes.
