Experiment: Investigating the Effects of Mass on Acceleration Against Another Mass
Atwood Lab

Abstract/Intro
In this lab we set up an atwood machine to find the with only variables known to be time, acceleration and distance. First we had to find an equation to solve for acceleration then rearrange that equation in order to find mass. Once we got in the lab we used to atwood machine by putting two weights on each end of the string so that there was no movement. We had to add paperclips to get it still. Once we had it equal we added a smaller mass and recorded the time and how far it had moved in order to find acceleration. Then with the value of acceleration we were able to successfully find the mass of the small washer. Materials
● Atwood machine
● String
● Large washer
● Small washer
● Paperclips
● Stopwatch
● Ruler
Methods
First we had to set up the atwood machine by adding a light string to the roller then putting two large washers on each end. We had to add paperclips to make the masses equal out. Then added a small washer to one end and recorded the time and distance in order to find acceleration.
We repeated the lab several times due to mechanical errors with the stopwatch and to make sure the numbers were precise. Once were had our numbers we were able to find the acceleration. Then with acceleration we were able to find the mass of the small washer.
Results
With the time and distance known we used the equation v2d/t to find the acceleration. Then plugging in our acceleration into the equation
2ma/(ga) we were able to find that the mass of the small washer was
9.53g and the large washers were 30.34g. Discussion
During the lab we were having problems with the stopwatch constantly so this may have affected our final mass considering pur times were longer than what they should have been. Plus it may have had low friction on the machine but that may have affected its acceleration at well so that was an unknown which we were not able to solve for. Conclusion
