Question

formulating a hypothesis: part ii
now you will focus on a second hypothesis. this hypothesis can be very similar to the first, but this time you want to focus only on the second variable in question, speed. what could be a hypothesis that would illustrate the relationship between speed and kinetic energy? use the format of \if...then...because...\ when writing your hypothesis.

Explanation:

A hypothesis is an educated guess. Kinetic energy formula is \(KE=\frac{1}{2}mv^{2}\), where \(m\) is mass and \(v\) is speed. If speed increases, kinetic energy should increase (assuming mass is constant) as per the formula.

Answer:

If the speed of an object increases, then its kinetic energy will increase because kinetic energy is directly proportional to the square of the speed (\(KE = \frac{1}{2}mv^{2}\), with mass \(m\) constant).
