Spring Launcher

Squeeze a spring and let it launch a block, or drop a block onto it. Find the squeeze.

Physics · Class 11 · Springs store and give back energy · 6 simulations. For JEE, NEET and your boards.

What you'll learn

  1. Stretch it: The spring's work is −½k(x₂² − x₁²)
  2. Launch speed: Spring energy becomes kinetic energy
  3. Buffer stop: A buffer stores the block's kinetic energy
  4. Ninety percent lost: Only the kept energy goes into the spring
  5. Hang and let go: Let go at the natural length: it falls to 2mg/k
  6. Drop onto the spring: Count the fall while it squeezes
