Claim: The car travels at a constant speed.
Evidence-
Procedure:
- Measure 6 distances that are 35 centimeters apart
- Use tape to mark the first distance
- Use tape to make a distance 35 centimeters before the 0 centimeter mark
- Allow the car to move at its maximum speed before starting the timer at the 0 centimeter mark
- Stop the timer after the back tires of the car cross the line
- Repeat steps for other distances and record data
DATA-
Reasoning:
The data found from this experiment supports the claim entirely. The car does move at a constant speed. After using a set of procedures and collecting data, it can be seen that the data shows that the car moves at a constant rate. When an object's motion is shown on a graph as increasing in a straight line, it is easy to conclude this. The graph and table both show that as the car moves a further distance, the time it takes for the object to get to the determined distance also increases. In order to further support the claim that the car travels at a constant speed, repeating the experiment could help.
By completing the test again, it becomes easier to see whether or not the time was accurate. For example, if during the second lab I were to find a different time for the distance, I could compare my initial recording. By using judgement, I could rule whether the initial data collected was accurate. Along with possible source of human error within reaction time, errors in measurement may have occurred throughout the lab. Measurement errors could lead to a lack of accuracy and possible outliers in the data. As stated before, by repeating the lab and procedures multiple times, a clear outlier would be defined.
