Throughout the reflection, make sure you have a copy of the Student Guide and your data tables. In this experiment, the
was intentionally manipulated. This was the independent variable.
The dependent variable measured was the

Mass, Speed and Kinetic Energy.

Explanation:

We can solve this by analysing the choices and the relations between variables.

Notice that Kinetic Energy depends on the speed and the mass. Actually the Kinetic Energy is directly proportional to those variables, which means the more mass or the more speed, the more Kinetic Energy would be.

Having said that, Part I and Part II must have speed and mass as indendepent variable, because Kinetic Energy depends on them.

Then, in the third question, the answer is Kinetic Energy becase that's the dependent variable in both cases Part I and Part II.

Just to remember, the Kinetic Energy is defined as

Where you can notice the relation between mass, speed and kinetic energy.

Therefore, the right answer are Mass (Part I), Speed (Part II) and Kinetic Energy (Part III).
