independent - different models of cars

control variables- accelerate to 60 mph

Independent variables are the variables in a study is that are get manipulated or changed to find or study the response or difference in the dependent variable. Here in this, the manipulation is a difference in the models of the cars.

The dependent variable is in this study or experiment is the distance both models took for each to stop after hitting the brakes as it depends on the independent variable.

Control variables are the variable is the variable that remains constant during the experiment so there would be no other influence than independent, in this case, speed or acceleration and same time hitting brakes are control variables.
