Question

a student is experimenting with launching a cannonball. they can measure the maximum height reached, the height of launch, the angle of launch, and the speed of launch.
if they want to investigate how the maximum height reached is affected by the height of launch, what independent, dependent, and control variables should they use?
independent variable:
dependent variable:
control variables:

Explanation:

The independent variable is the one that is deliberately changed. Here, the student wants to see how the maximum height is affected by the height of launch, so the height of launch is the independent variable. The dependent variable is the one that is measured and changes in response to the independent variable, which is the maximum height reached. Control variables are those that are kept constant to ensure that only the independent variable affects the dependent variable. In this case, the angle of launch and the speed of launch should be kept constant as control variables.

Answer:

Independent Variable: Height of launch
Dependent Variable: Maximum height reached
Control Variables: Angle of launch, speed of launch
