FALLING CHIMNEY
APPARATUS
hinged board on hinged
brace
202-14-A
steel ball
202-14-A
DESCRIPTION
Prop the hinged board at an
angle using the brace, which fits into the notch at the end of
the board. Place the ball in the depression at the top of the
hinged board. Knock out the brace and the ball will land
in the cup, showing that the free end of the board has an
acceleration greater than g. The angle between the board
and the table is less than 35 degrees.
A LoggerPro file with a slow motion video is available.
In it, the positions of the ball and the end of the board are
tracked and plotted against time.
