Question

question 2: control variables for the tire pressure experiment, the video mentions using \the same car each time\ as a control variable. a) why is this important for the experiment? b) list three other control variables that should be kept constant in this experiment: 1. 2. 3.

Explanation:

a) Using the same car each time ensures that variables specific to different cars (such as weight, tire - type, and wheel size) do not affect the results. This allows for a more accurate assessment of the impact of tire pressure alone on the measured outcome.
b) Three other control variables could be: the type of road surface (as different surfaces can affect tire - related measurements), the speed of the car (since speed can influence tire performance), and the weather conditions (as temperature and humidity can impact tire pressure and behavior).

Answer:

a) To isolate the effect of tire pressure by eliminating car - specific variable influences.
b) 1. Type of road surface

1. Speed of the car
2. Weather conditions
