Experiment 2 Newton s Third Law and Force Pairs In this experiment you will investigate Newton s Third Law of Motion by observing forces exerted on objects Materials 5 N Spring Scale 10 N Spring Scale 2 30 cm Pieces of String 0 5 kg Mass Pulley Procedure Part 1 1 Make sure the spring scales are calibrated using the standard masses 2 Hook the handle of the 5 N spring scale to the hook of the 10 N spring scale 3 Holding the 10 N spring scale stationary pull the hook of the 5 N spring scale until the force reads 5 N on it Record the force on the 10 N spring scale in Table 3 4 Repeat Steps 2 and 3 with the 10 N spring scale hanging from the 5 N spring scale Record the force on the 5 N spring scale in Table 3 Part 2 1 Suspend the 0 5 kg mass in the air using the 10 N spring scale Record the force on the 10 N spring scale in Table 4 2014 eScience Labs LLC All Rights Reserved 2 Tie one end of one of the pieces of string to the 0 5 kg mass and the other end to the hook of the 10 N spring scale 3 Suspend the mass in the air by lifting the 10 N spring scale Record the force on the 10 N spring scale in Table 4 Table 3 Force on Stationary Springs Force on Stationary 10 N Spring Scale N 5 0 N Force on Stationary 5N Spring Scale N 5 0 N 4 Untie the end of the string attached to the 0 5 kg mass and tie it to the hook of the 5 N spring scale 5 Hook the 0 5 kg mass to the handle of the 5 N spring scale Suspend the mass scales and string by holding the handle of the 10 N spring scale Record the values Figure 5 Pulley Set Up of the spring scales in Table 4 6 Secure the pulley on a table top by tying string to one of the hooks Then use masking tape to secure the string to a table top so that the hook on the top of the pulley lays flat on the side of the table top Figure 5 7 Using the mass setup from Step 5 place the string over the pulley by unhooking one of the spring scales feeding the string through the pulley and reattaching the string to the hook of the spring scale Figure 6 8
