Conservation of Energy (Elastic)
📚 Key Concepts
  • Momentum is always conserved in collisions
  • In elastic collisions, kinetic energy is conserved
  • Heavier objects transfer more momentum
  • Equal mass objects exchange velocities
  • No energy is lost to heat or deformation
🔬 Try This
  • Collide two equal mass balls
  • Make one ball 3x heavier than the other
  • Try a stationary target ball
  • Add multiple balls and watch chaos!
  • Observe momentum conservation in stats
