Question

in a controlled experiment, a student is trying to determine how the angle of the launch of a bottle rocket affects the distance it travels. what is the independent variable in this experiment?

Explanation:

In an experiment, the independent variable is the factor that is manipulated or changed by the experimenter to observe its effect on the dependent variable. Here, the student is changing the launch angle of the bottle rocket to see how it affects the distance traveled. So the independent variable is the angle of the launch of the bottle rocket.

Answer:

The independent variable in this experiment is the angle of the launch of the bottle rocket.
