Purpose
The purpose of this lab is to measure the amount of time it takes for a toy car to travel a meter.
Materials
Battery-powered Vehicle
Stop Watches
Meter Sticks
Place Markers
Procedure
1) Get the materials
2) Set up timer
3) Set the toy car at the beginning of the meter stick on the floor.
4) Turn on the timer and let the car go.
5) Record the time when the car reaches 30 cm, 60 cm, 90 cm, and when it reaches the end of the meter stick.
6) Record all your data.

Calculations/Results
Equation: y = 29.85x + 0
Variables: time (x) & position (y)
m = 29.85
Y-intercept: 0
Error Analysis
1. The purpose of this lab was to measure the amount of time
it takes for a toy car to travel a meter.
2. We found that we could never get a perfect measurement of the time it took the car to travel a certain distance, due to human error. This gave us slightly different times at each checkpoint, affecting the data's equation. Another error we discovered, was the car drifted to the left. Because of this problem, the time was different than if had been going straight.
Questions
1. What can you say about the motion of the buggy from the graph in your data (describe the motion)?
We can declare that the buggy was traveling at a positive constant speed.
2. What does the slope of this line tell you (what does that number mean)?
The slope of the line tells us how many centimeters the buggy traveled per second.
3. Could you use this equation to predict anything, if so what?
We could use this equation to predict how long it would take for the buggy to travel a certain distance.
4. Why did you decide to do the procedure the way that you did?
We decided to do the procedure the way we did because we thought that measuring the amount of time it took the buggy to travel a meter would give us more precise data.
