Question

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.

Answer 1

Explanation :

The kinetic energy is the energy of an object which is possessed due to its motion.

Mathematically, the kinetic energy can be written as :

$KE=\dfrac{1}{2}mv^2$

Where

m is the mass of an object

v is the velocity with which the object is moving

So, it is clear that there exists a direct relationship between the speed and the kinetic energy of an object.

Hence, if the speed of an object increases its kinetic energy will also increase because there is a direct relationship between the speed and the kinetic energy.

Answer 2

If the mass of an object increases, then its kinetic energy will increase proportionally because mass and kinetic energy have a linear relationship when graphed.
