Experimentation 1. To test Hypothesis 1, crumple a piece of paper until it is
approximately the same size as the stone. Then, drop the two objects
from the same height. 2. To test Hypothesis 2, slightly crumple a second piece of paper so that
its size is greater than that of the first piece. Drop the two crumpled
pieces of paper from the same height. 3. To test Hypothesis 3, fold one piece of paper into an airplane. Leave
the other piece unfolded. Drop the two objects, face down, from the
same height. 4. Plan a way of testing Hypothesis 4. Questions:
1. For experiment 1, which object is heavier? Which one falls faster?
Does weight affect an object’s rate of fall?
2. For Experiment 2, which object falls faster? Does the size of an object
affect its rate of fall?
3. For Experiment 3, which piece of paper falls faster? Does the shape
of an object affect its rate of fall?
4. Does the weight, size, and shape of an object affect its rate of fall in

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).
