## Forces (Y5)

Prior learning

• Compare how things move on different surfaces. (Y3 - Forces and magnets)

• Notice that some forces need contact between two objects, but magnetic forces can act at a distance. (Y3 - Forces and magnets)

• Observe how magnets attract or repel each other and attract some materials and not others. (Y3 - Forces and magnets)

• Compare and group together a variety of everyday materials on the basis of whether they are attracted to a magnet, and identify some magnetic materials. (Y3 - Forces and magnets)

• Describe magnets as having two poles. (Y3 - Forces and magnets)

• Predict whether two magnets will attract or repel each other, depending on which poles are facing. (Y3 - Forces and magnets)

Future learning

• Forces as pushes or pulls, arising from the interaction between two objects. (KS3)

• Using force arrows in diagrams, adding forces in one dimension, balanced and unbalanced forces. (KS3)

• Moment as the turning effect of a force. (KS3)

• Forces: associated with deforming objects; stretching and squashing – springs; with rubbing and friction between surfaces, with pushing things out of the way; resistance to motion of air and water. (KS3)

• Forces measured in Newtons, measurements of stretch or compression as force is changed. (KS3)
