"Give me a lever long enough and a fulcrum on which to place it, and I shall move the world." — Archimedes said this over 2000 years ago, and he was right! A small child can lift a car with a long enough lever. A door handle is placed far from the hinges because it's easier to push there. This is the physics of MOMENTS — turning forces that depend not just on how hard you push, but WHERE you push.
This introduction covers The Power of Leverage within Moments & Levers for GCSE Physics. Revise Moments & Levers in Forces for GCSE Physics with 13 exam-style questions and 10 flashcards. This topic appears regularly enough that it should still be part of a steady revision cycle. It is section 1 of 14 in this topic.
