Austin Green No lab partner Conclusions Summary: In this lab we had a glider accelerate along an inclined air track under the force of gravity. I measured the velocity at several different point to find out whether there was constant acceleration or not. Specifics: The acceleration I ended up with was 11.8 cm/s^2 on the graph, and the theoretical acceleration was around 12.5 cm/s^2. Which shows that my uncertainties were correct. My V1 that I computed turned out to be 21.93 cm/s and my theoretical velocity was at 22.14 cm/s. These two values were very similar, so that showed that I was consistent in my calculations. The V1 off the graph is the y-intercept, which ultimately tells you the

Unformatted text preview: initial velocity. • I found the acceleration to be constant by examining my graph after I finished it. With all the points lining up with the weighted least-square fit line, it shows that the acceleration is constant. Error Analysis: • The possibilities of the error between my acceleration and my velocity could be due to the fact that every experiment has some random error for no particular identifiable reason. • Also, the photogates could have been slightly different and caused a slight error in the measurements. Things including the length and time could have differed between the two photogates....
