Spring 5N Spring Scale EXPERIMENT 1: WORK DONE BY A SPRING In this experiment you will investigate the work done by a spring PROCEDURE 1. Zero the 5 N spring scale. 2. Lay the ruler on the table with the centimeter scale closest to you. 3. Place the end of the spring with the circular hook next to the ruler so that the end of the spring lines up to the 0 cm mark on the ruler (Figure 7). 4. Hook the spring scale onto the circular hook of the spring. Make sure the Newton scale is visible so you will be able to make measurements. Science Labs. Figure 7: Step 3 reference. Notice that the end of the free spring is lined up to the 0 cm mark of the ruler. 5. Secure the spring by grabbing 10 coils from the opposite end of the spring. Note: It is important that you always secure 10 coils of the spring. If possible, do not let go of the spring while recording data. 6. Pull the spring scale until the end of the spring is stretched to the 5 cm mark on the ruler. Record the force reading on the spring
