Bus Pendulum

No windows. Only a hanging bob. Find how the bus is moving, from inside it.

Physics · Class 11 · Pseudo force in an accelerating bus · 7 simulations. For JEE, NEET and your boards.

What you'll learn

  1. Read the bob: A hanging bob is an accelerometer
  2. Swing it forward: Braking swings the bob forward
  3. The helium balloon: Effective gravity inside the bus
  4. Water tank: A water surface lies across effective gravity
  5. Down the slope: A freely rolling frame tilts “down”
  6. Drop the ball: Falling inside an accelerating bus
  7. Floor pressure: Floor pressure in an accelerating tank
