1.5.2 — Turning effect of forces

Core

• 1.5.2.1 — Describe the moment of a force as a measure of its turning effect
• 1.5.2.2 — Define moment = force × perpendicular distance from pivot; recall and use the equation
• 1.5.2.3 — Apply the principle of moments to simple situations
• 1.5.2.4 — State that an object is in equilibrium when there is no resultant force and no resultant moment

Supplement

• 1.5.2.5 — Apply the principle of moments to more complex situations
• 1.5.2.6 — Describe an experiment showing no resultant moment on an object in equilibrium
