Kinematics. Purpose: Using a Baseball, find how the velocity and acceleration change from when a baseball is thrown

Data Table: See Excel Spreadsheet

Data Analysis: See Excel Spreadsheet

Conclusion:

As the Distance from the starting point increases, the time it takes to travel increases, meaning the velocity and acceleration also increase. The Lab was very successful because I was able to successfully complete my purpose statement successfully

 Evaluation:

Even though the lab is successful, there was still some error as shown in the graph with the error bars, but the uncertainty is low enough it is relatively accurate. Any error could be due to a change in power used to toss the ball, which would affect the time it would take to reach each point, but it would be so small it wouldn’t affect the lab. Another possible error to the lab would be I threw the ball, and also timed it, so there is manmade error because I am not able to time exactly as well as throw the ball at a constant speed. This would affect the velocity and acceleration because the time could be off

Improvements:

One Improvement of this lab would be to somehow use photogates to get a more accurate reading on the time instead of using a stopwatch, thus creating a successful and accurate experiment. Another improvement that could be made would be to have some machine that could output a constant force on the baseball, like a pitching machine, allowing for an equal force when the ball is thrown. One last improvement that could be made to is lab would be to have someone else help me when I am doing my lab, because then I can be focusing on tossing the ball and my partner could time it as I am throwing it, making it more accurate overall.
