Physics 1020 Laboratory #4 Force and Acceleration Introduction Newton’s second law states that the net force acting on a system of masses gives the system an acceleration such that For a system such as is pictured at right, the force of gravity is able to accelerate both masses because the tension force in the string changes direction over the pulley. Using Newton’s second law we find: where W B is the weight of mass B and f is the force of friction on mass A. You will derive this result in the workbook. F m a B A W B ( m A m B ) a f

Physics 1020 Laboratory #4 Force and Acceleration Part II: Setup Putting together the equipment.
Background image of page 6
Physics 1020 Laboratory #4 Force and Acceleration Equipment The setup consists of a dynamics cart, plastic card, a track, photogates, a pulley, string and a set of masses. Set it up as pictured while taking care to do the following: The photogates need to be attached to the track by brackets and they should be located at 30 cm and 80 cm so the card is not blocking the photogate when it starts or stops. To attach them you will need to slip the nut into the groove on side of the track and then screw the support rod into the nut. Then you can screw the photogates in the top of the rod. Connect the 1 st and 2 nd photogates (in the order the cart passes) to the LabPro in ports DG1 and DG2 respectively.
