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

A pull is force that brings an object closer.

Gravity is the force that attracts objects to Earth.

If something is unsupported, it is not held up by anything.

Design and development of machines

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

This unit covers the effects of gravity, air resistance, water resistance, and friction on objects. It explores how mechanisms like levers, pulleys, and gears magnify forces. Emphasis is on taking precise measurements, recording complex data, and presenting findings.

Physical activity and equipment requiring safe use

Use of equipment that may require supervision for safety, e.g. scissors in KS1, needles, paint, knives, cooking.
