Interactions over small and large distances — AQA GCSE Combined Science Synergy

Your focus

1. This topic looks at strong forces and weak forces between atoms, molecules and much larger structures. Understanding how these interactions take place helps to explain how matter behaves, and enables engineers and scientists to design materials that can withstand forces and to provide the materials and devices that we need for a wide range of purposes. The communications, security and transport industries make great use of electromagnetic forces to control and move devices.
