Cue Shot

Strike a ball or pull a spool's thread. Find when it skids and when it rolls.

Physics · Class 11 · Sliding and spinning together · 6 simulations. For JEE, NEET and your boards.

What you'll learn

  1. Tap on ice: A blow off the centre: it slides and spins
  2. Push at the axle: A pull on a roller: two equations
  3. Pull the top thread: A thread off the top: friction can push forward
  4. Skid, then roll: Skid, then roll: L about the floor stays the same
  5. Cue height: No skid: hit at h = R(1 + β)
  6. Top spin (JEE Adv): Top spin: take L about the contact point
