Question

Throughout the reflection, make sure you have a copy of the Student Guide, PDF or Word, and your data tables. Use the drop-down menus to complete the statements.
This activity was a multistep laboratory. Think about each step and identify the variables.
In all three parts, the dependent variable was .
The independent variable is the one that the scientist intentionally manipulates. In Part I involving the golf ball and table tennis ball, the independent variable was .
In Part II involving the inflated and deflated footballs, the independent variable was .
In Part III involving the baseball, the independent variable was .

Answer 1

Answer:

We can solve this by analyzing 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 independent variable, because Kinetic Energy depends on them.

Then, in the third question, the answer is Kinetic Energy because 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).
