1. The problem statement, all variables and given/known data 1. Compare the mass of the system to the slope. Does your data support Newton's Second Law? 2. Using the words "directly" or "indirectly" briefly explain how force, mass, and acceleration are related to each other, making specific references to the parts of the Fletcher's apparatus used in this lab. The mass of the system is 2.7kg, while the slope of the best fit line (Fn on y-axis and a on x-axis) is 2.5kg. 2. Relevant equations Fnet = ma 3. The attempt at a solution For 1., I stated that my best fit line was close to the actual mass of the system. However, I don't understand how to explain the second part regarding Newton's Second Law. 2. It was obvious to me that force was directly proportional to force and mass, both theoreticall and experimentally. However, I ran into trouble when I was comparing mass and acceleration. Although they should be inversely proportional from the formula (multiplying and same side of equation), both increase at the same time (although non-linear) from the experimental data. Thanks.
