Measuring the Mass of a Chocolate Candy
| Use a pencil lying on its side as a fulcrum. Tape each end to
the desktop to prevent it from moving during the remainder of the experiment.
|
| Use the ruler, the calibrated mass, one hard-shelled chocolate candy,
and your knowledge of rotational equilibrium to determine the mass of the
chocolate candy.
