Buggy Lab

Pre-Lab observations

-Stays in a straight line
-moves
-noise
-has head lights and antenna
-wheels
-red
-forward only
-keeps going
-two seats

 

Objective
What is the relationship between it's position and time?

The Plan
For both our trials we will start the buggy at zero and time how long it takes for it to move 20 inches constantly.add a bit more - how will you time it?  who will do what job?

Data Analysis 

-Trial 1 

why so many decimal places?

-Trial 2

Data Graph

VM - As the position increases, the time increases proportionally
MM -  Position = (20.8 in/sec) time + -20.8in
Slope - For every second, the position increases 20 inches
Y-int - The the amount of seconds equal zero the position is -20.8 inches

 

VM - As the time increases, the position increases consistently 

MM - Position = (19.7 in/sec) time+ -9.5 in

Slope - For every second,  the position increases 10 inches  why 10?  isn't it 19.7?  or 20 if you round?

Y-int- The amount of seconds equal zero the position is -9.5 inches    

Conclusion
In each of the experiments the buggy was moving in either a positive  direction position or a negative position, this made the slope positive or negative. All of the buggy's move at a constant speed so all the experiments have a linear trend. Since all of the buggy's speeds are similar, all graphs have a similar slope. Even though they have similar slopes they each have a different starting position so each graph has a different y-intercept.nice!
In our experiment we had a few errors. Our reaction time for the timer was not completely accurate. Also our marks for when to stop the timer differed slightly each time. A better way to have gotten our data would be to take a video of the buggy moving next to the meter sticks and to pause the video to time the Buggy at a more accurate mark.great idea!!

Journal Statement 

I liked this experiment because it was a good one to start the year off with so that we could get used to how to do these lab blogs. good!
