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.

If the mass of an object increases, then the kinetic energy of the object will also increase, because according to the equation for kinetic energy (KE = 0.5 * m * v^2), an increase in mass directly leads to an increase in kinetic energy as long as the velocity remains constant.
