Description | ||
This experiment was conducted to ascertain the relationship between the stiffness or hardness of a tire and the speed that can be achieved by a racing car. Three types of tires of different stiffness/hardness are tested using go-kart vehicles. | ||
Instructions preview | ||
*For this experiment, the independent variable is the type of tires used (soft, medium and hard tires). The dependent variable is the time taken to complete 3 laps in each circuit. This is determined by using a stop watch to measure the time taken to complete the 3 laps. The constants (control variables) are the number of laps, the capacity of the go-kart and the skill of the driver. It is important for the go-kart driver to be very familiar with the circuit in order for this experiment to work. *The experiment is carried out on 3 different go-kart ..... |
