  • Nuts are tied to two separate ropes. Spacing between nuts on rope 1 is constant; spacing between nuts on rope 2 goes as the square of the distance from the end of the rope.
  • Hang ropes vertically and drop onto wooden platform. When rope 1 falls sound made by nuts (hitting board) increases in frequency, indicating acceleration of rope. When rope 2 falls, the nut-hitting-board sound is periodic, due to r^2 spacing.
  • Note: When hanging string, first nut (on bottom of string) rests upon board. So first nut does not fall- merely used as an a position anchor.

  • Purpose: Show that an object’s acceleration, under the influence
    of gravity, is un-effected by the objects velocity.
  • Cock mechanism; place pin in hole to keep cocked; place balls
    on ends; release pin to eject balls.
  • One ball drops vertically, with zero initial velocity; other
    ball launched horizontally. Balls hit floor simultaneously.
