A force is a push or a pull. Forces can make objects move, slow down, change direction or change shape.

A lever is a simple mechanism or machine which is useful for lifting things.

The load is the object you are lifting with a lever.

The effort is the force needed to do a job.

The pivot is the fixed point where a lever turns.

Science

In this Forces and simple machines unit, pupils learn that air resistance, water resistance and friction push back against moving objects. In this Forces unit, pupils will build on this knowledge to accurately describe and explain the actions of forces in a range of situations.

In the Simple forces including magnets unit, pupils learnt to compare how things move on different surfaces. In this Forces including simple machines unit, pupils will build on this knowledge to identify the effects of air resistance, water resistance and friction, that act between moving surfaces
