Hammer Throw

Whirl a hammer and let it go. Find its speed, the pull you hold, and where it flies.

Physics · Class 11 · Speed and pull on a circle · 8 simulations. For JEE, NEET and your boards.

What you'll learn

  1. Spin to speed: From rpm to speed: v = ωr
  2. Hold the pull: The pull on the wire: F = mω²r
  3. Through the gate: It flies off along the tangent
  4. A quarter turn: Same speed, new direction: the velocity changes
  5. Equal pulls: Speeding up: aₜ stays, ac grows
  6. Which way it pulls: The wire leans ahead: tan φ = at / ac
  7. The fan winds down: Slowing evenly: use the average spin
  8. Arrow at 37°: Acceleration as a vector: a = −(v²/r) r̂
