Introduction- The purpose of this lab is to understand and use Newton’s Second Law. The Law has to deal with Work being equal to mass times acceleration, or force. F=M x a 1. M1 x a1= M1g-T1 2. M2a2=T2-f but T1=T2=T and a1=a2=a Solve for external force by solving 2 for T and plugging into 1 for M1g. M1g=(M1 + M2)a + F Aavg= (v2-v1)/(t1-t2) Mcalc= Mcart + Mhanger + Mweights

Our percent error was low, with our calculated value being smaller than that of the slope of the linear regression....
