Activity 4 (Graphical Analysis of Motion)

This Activity took a long time to finish. First, there was the Best Fit Line discussed by our guest lecturer, Mr. Justine Uro. Second, we made graphs on excel with error bars and trend lines. Third, we gathered data through timing the cart on an air track when it reaches a particular distance. Last but not the least, we made a technical paper about the experiment we did.

Last year, December 8th, We were taught about the Best Fit Line. I haven’t heard of it before, I thought it was just a line that one could by connecting the origin to the mean of the graph. Somehow I was right, but obtaining the mean is not enough. There were many equations to be considered before we could say that it is the "best-fit line", though I wasn't able to remember them all.




 
We then made an experiment and gathered data. Using Microsoft Excel, we were able to get the trendline and the equation that would represent the relationship of each measurement.
