## C2-06 BALL DROP ON ROPE - EQUAL AND UNEQUAL INTERVALS

• ID Code: C2-06
• Purpose: Illustrate the geometrical effect of free fall
• Description: Two ropes of equal length have steel balls tied at five points along their length. One rope has the balls at equal distances along the rope, while the second has balls positioned geometrically, at distances proportional to the squares of integers: 1, 4, 9, 16, and 25. When the first rope is dropped the equally spaced balls hit the floor at progressively shorter time intervals; when the second rope is dropped, the geometrically positioned balls hit the floor at equal time intervals. NOTE: This demonstration can only be properly done in the lecture halls because it requires 12 feet of height to fully extend the ropes.
