Exploring the Relationship Between Force and Acceleration

What is the independent variable in the student's investigation?

A. the acceleration of the wagon

B. the force acting on the wagon

C. the mass of the wagon

D. the mass of the student

Answer:

The independent variable in the student's investigation is the force acting on the wagon, which is option B.

Variables are factors in an experiment that can be changed, and these changes result in changes in the result of the experiment. There are three types of variables: dependent variable, independent variable, and constant variable.

In the experiment by the student, the independent variable is the force acting on the wagon. Changes in the force on the wagon will result in changes in the acceleration of the wagon. Therefore, the force acting on the wagon is the independent variable that the student will be investigating.

In conclusion, the independent variable produces changes in the dependent variable when it is changed, allowing the student to study how the acceleration of the wagon changes as the force exerted on it increases.
