Is the expression "the bigger they are, the harder they fall" a generally true statement since, in the absence of air resistance, all objects fall with the same acceleration due to gravity? pick the most correct answer.
yes, because as a heavier man falls, he comes closer to the center of the earth and he falls faster.
no, since the acceleration is the same, each man will be affected the same by it as he falls.
yes, since f = ma, therefore "a" will be the same in each case, but the mass of each will be different.
yes, since f = ma, the heavier an object is, the more it will accelerate and therefore fall with more force.

Since the investigative question has two variables, you need to focus on each one separately. thinking only about the first part of the question, mass, what might be a hypothesis that would illustrate the relationship between mass and kinetic energy? use the format of "if…then…because…” when writing your hypothesis.
