Discuss Q1. Are the values of a 1 , a 2 and a 3 compatible with each other? Comment and justify your ans No, the values of a1 , a2 and a3 are not comptaible with each other since for our first ac 43.25cm/s2 and for our last acceleration, we got a value of 43.4cm/s2. As we can tell, the va can be explained due to the fact that the first method had so many uncertainties propagatin (±2>±0.03 and ±0.5). The experimental setup may have measurement errors or uncertainti quadratic and linear regression methods rely on mathematical equations that make certa especially if there is friction or air resistance. The value of the first acceleration could also be amounts of friction that could affect the motion. Q2. Describe the possible sources of uncertainty that can directly explain the uncertainty of th There's a high number of sources of imprecision in any laboratory and our job is simply to try t assignment, there are a few factors that may have led to ambiguity when it came to determinin Although air tracks are designed to reduce said friction significantly, it can never be 100% and such as the ruler, have a pretty low measurement resolution and therefore can limit the accura Q3. Give an expression for ∆ a 1 showing all your work. Then plug the values you measured int You can do this on a piece of paper and then add a picture of your work below.
