Moments, Pressure & Hooke's Law
Calculate the turning effect (moment = force × perpendicular distance), explain how pressure is transmitted equally in liquids (Pascal's principle) and the concept of atmospheric pressure, and describe Hooke's Law (extension ∝ force up to the elastic limit)

“If your child was using a long spanner to loosen a tight bolt, could they explain why a longer spanner makes it easier — and work out what force would be needed with a spanner of a specific length?”

- Resultant Forces
Moments and pressure are applications of force — understanding forces as vectors and resultant forces provides the foundation
- Levers, Pulleys & GearsREQUIRED
KS3 moments and mechanical advantage extends KS2 introduction to levers, pulleys and gears allowing smaller force for greater effect
