Given that there was a race car track built and the height was being elevated while the time was being recorded.
Let's determine the independent and dependent variable.
In this experiment, since the height was being elevated, we can say the height of the track was intentionally manipulated.
The independent variable can be said to be the variable that is changed or controlled.
Therefore, the independent variable is the height of the track.
The dependent variable is the variable which depends on the independent variable. It is the variable measured.
Since the time was being recorded for how fast the race car went down the ramp, the speed is the dependent variable because it depends on the height of the track.
Therefore, the deendent variable measured was the speed of the car.
ANSWER:
• In this experiment, the ,height of the track_, was intentionally manipulated. This was the independent variable.
• This dependent variable measured was the ,speed of the car.
