Newton’s 2nd Law experiment using an inclined plane Purpose Thislab experiment is to verify Newton’s second law and in the processalso obtain the coefficient of kinetic friction between a block andan incline. Theory Newton’s 2nd law states that the net externalforce on an object in a given direction is equal to the mass of theobject multiplied by its acceleration, Fnet = ma, where m is themass of the object and a is its acceleration. Applying Newton’s 2ndlaw to the two objects as shown in the figure below, we obtain: m1g– T = m1a (1) T – m2gSin – fk = m2a (2) where fk = kFn (3) and Fn= m2gCos (4) from (2),(3), and (4) T = m2a + m2gSin + km2gCos(5) From (5), and for  = 0, T = m2a + km2g (6) Following equation(5), a graph of T vs. a should give a straight line where the slopewill be equal to m2, and the coefficient of kinetic friction may beobtained from the intercept, since the intercept will be equal to(m2gSin + km2gCos) Procedure Open the simulation athttps://ophysics.com/f3.html a. Choose a constant value for massm2. b. Choose a value for  c. Choose a coefficient of friction lowenough for the masses to move, and keep this coefficient constant.Verifying the acceleration d. Choose a value for m1 e. Using the“run” and “pause” buttons, run and pause make a table of at leastseven data sets of h (take the absolute value) and time. f. Make agraph of h vs. time, and an appropriate curve fit to obtain theacceleration from your graph. (Hint: x = vit + ½ at2) g. Comparethe acceleration from your graph with that provided by thesimulation. Verifying Newton’s 2nd Law h. Vary m1, and record thecorresponding acceleration, a, and tension, T, for several (atleast seven) values of m1. i. Create a table for T vs. a j. Make agraph of T vs. a k. Choose an appropriate curve fit to obtain m2and k from your graph (Hint: Equation 5) l. Compare the m2 and kfrom your graph to the actual m2 and k m. Repeat steps g to kusing  = 0 (Hint: equation 6) n. Compare the two k valuesobtained from j and k. (do a percent difference) Questions 1. If aconstant nonzero force is applied to an object, what can you sayabout the velocity and acceleration of the object? 2. Why can weneglect forces such as those holding a body together when we applyNewton’s second law of motion? Sources: 1. CCSU Physics Lab Manual2. Ophysics.com 3. OpenStax College Physics
