Friction forces are forces which act between the surfaces of objects.

The surface is the top or outside layer of something.

A grip is a firm hold or tight grasp, between objects and surfaces.

The properties of a material are its qualities or things it can do.

In this Simple forces including magnets unit, pupils learn to compare how things move on different surfaces. In the 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

In the Everyday materials unit, pupils learnt to compare and group together materials on the basis of their simple physical properties. In this Simple forces including magnets unit, pupils will build on this knowledge to compare and group materials on the basis of whether they are attracted to a magnet or not

This unit explores how objects move on different surfaces and examines magnetic forces, including attraction, repulsion, and magnetic materials. It covers identifying magnetic poles and predicting interactions and emphasizes practical tests, observations, and presenting findings.

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

Which of the following can be caused by friction forces?

When scientists and engineers design products, they choose materials that are suitable based on their {{}}.

A large amount of friction force can be helpful for which two of the following products?

When I rub the palms of my hands together, this creates friction force, and I can feel {{}}.

When products are made, materials are chosen based on their properties. Which two of these products would need a high friction material?

In which sport would friction forces be unhelpful?

Which word is used to describe what a material can do or how it behaves?

The rougher the surface, the {{}} the friction forces.

Starting with the least friction force, order these surfaces by how much they would slow down a marble travelling on them.

Starting with ice rink, order these surfaces by the amount of friction forces they would create.
