1C20.10 - Paper and Lacrosse Ball


Paper & Lacrosse Ball Demo
Paper & Lacrosse Ball Demo



Code: 1C20.10


Demo Title: Paper and Lacrosse Ball


Subject: Uniform Acceleration


Description:
Air resistance is demonstrated using lacrosse ball and a sheet of paper. By dropping the lacrosse ball and paper at the same time towards the box of sand audience sees how air resistance effects how bodies fall. When the paper is crumbled and dropped with the lacrosse ball they fall at the same rate (air resistance is removed in part by crumpling the paper into a ball).


Procedure:

  • Hold lacrosse ball and paper at same height over box of sand
  • Drop both objects at same time
  • Explain air resistance is effecting the objects.
  • Crumple paper into a ball.
  • Repeat the demonstration again with paper in ball shape.
  • Explain to audience why the paper and lacrosse ball now fall at the same rate.
