⏱️ Simple Pendulum

Explore simple harmonic motion and energy conservation with an interactive pendulum

Difficulty: ● Easy

📐 Physics Formulas
T ≈ 2π√(L/g)
Period of pendulum (small angles)
F = -mg sin(θ)
Restoring force
E = mgh + ½mv²
Total mechanical energy
📚 Key Concepts
  • Period is independent of mass
  • Period increases with length
  • Energy is conserved (no damping)
  • Simple harmonic motion for small angles
  • Maximum velocity at lowest point
🔬 Try This
  • Double the length - what happens to period?
  • Change mass - does period change?
  • Try very small vs large angles
  • Simulate Moon gravity (1.6 m/s²)
