- 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.

- Demonstrate the dependency of terminal velocity on mass and
surface area.
- Instructions included.
