Group 1
Pre-lab observations:
- Constant speed
- Positive and negative movement (position)
- Placement on the number line - single point
- Turned around
- Lights up
- Red
- Black wheels
- Flower pattern
- Noise
- Antenna
- Batteries
- Distance
Objective: We are trying to figure out the different positions of the buggy after moving in both a positive and a negative direction. as compared to the time...state both variables
Our plan: Our plan is to measure out six end points with a length of 12 inches each for a total of 72 inches. After that, we will turn on the buggy and place it at the starting position 12 inches away from the first end point. Then we will record the time it takes to get to that end point and then do the same for the other 5 end points.
Trial 1 Data:
units for position ?

Trial 1 Data:
units for position ?
Time (sec) | Position
We moved the buggy in a positive direction and recorded data from 0 inches to 72 inches
VM: As the time the buggy traveled increased in seconds, the position of the buggy measured in inches also increased proportionally
MM: Position = (18 in/sec)time - 1 in
Slope: For every one second of time it passes, the buggy's position increases by 18 inches
Y-intercept: When the time is zero seconds, the starting position of the buggy is -1 inch.
Trial 2 Data:
units for position?
Time (sec) | Position
VM: As the time the buggy traveled increased in seconds, the position measured in inches decreased proportionately
MM: Position = (-18 inches/sec)time + 87 inches
Slope: For every one second of time that passes, the position of the buggy decreases by 18 inches.
Y-Intercept: When the time is zero seconds, the starting /////position of the buggy is at 87 inches
Conclusion: In the lab, there were many claims and evidence to back our observations. First we observed that the buggy went at roughly the same speed as the buggies from other lab experiments. The reason for this is because almost all the other lab reports showed large slopes, which defined the speed and how fast the buggies went. We also observed that all of the buggies had different starting positions. Most of the buggies from the trials had different y-intercepts, some were positive while others were negative. Finally, we saw that many groups placed their buggies in both positive and negative directions. We observed this because the graphs increased or decreased depending on the data. However, we experienced a number of errors during this trial. The most common error was reaction time when we recorded the data of the buggy's position through the timer of our phones. We cannot say that we precisely recorded the data. can you improve that? how? or not? If I were to improve this lab, I would have changed more than just the change of positive/negative direction of the buggy. For example, I would have added weights and inclined slopes in order to produce even more intriguing yet different trial datas.
Journal Statement: Overall, this lab was a nice experiment to kick off the new year of Physics. It was easy and straight to the point, although as a class we struggled to stay on task and complete it faster. However, jumping into the topic of constant velocity without going over the basic lab procedures made things tough and a little frustrating at first. I do hope in the future that we can work on more labs as fun as this one was.good!!!
