Pendulum Clock

Keep a pendulum clock on time. Take it into a lift, a bus, under water or to a planet.

Physics · Class 11 · The simple pendulum · 8 simulations. For JEE, NEET and your boards.

What you'll learn

  1. Seconds pendulum: The simple pendulum: T = 2π√(L/g)
  2. Clock in a lift: In a lift, use geff
  3. Clock in a bus: A sideways push adds at right angles
  4. Another planet: g on a planet: g = GM/R²
  5. Bob under water: Under water, buoyancy weakens g
  6. Read g from a graph: g from the slope of T² against L
  7. In step with a spring: Match a pendulum to a spring
  8. Will the string hold?: The string pulls hardest at the bottom
