Moments, Pressure & Hooke's Law

Science · Forces & Motion · conceptual

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)

What mastery looks like

  • Calculates the moment of a force and uses the principle of moments to solve lever problems
  • Explains why hydraulic systems can multiply force (pressure transmitted equally)
  • States Hooke's Law and plots force-extension graphs identifying the elastic limit
  • Calculates spring constant k from a force-extension graph (k = F/x)

Check your understanding

If Moments, Pressure & Hooke's Law 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?
