Collision Lab

Crash carts on a smooth track. Set the bumpers and find the speeds after.

Physics · Class 11 · Collisions in a line · 8 simulations. For JEE, NEET and your boards.

What you'll learn

  1. They stick: Stuck together, momentum stays the same
  2. Where did the energy go?: A sticking hit loses kinetic energy
  3. Bounce back: Elastic: KE and momentum both stay the same
  4. The hidden cart: Separation speed equals approach speed
  5. Row of beads: Equal masses, elastic: they swap velocities
  6. Spring bumper: The squeeze is largest when both move together
  7. Set the bounce: e sets how fast the carts part
  8. Head-on: Head-on: keep track of the signs
