Hang the 100 g mass on the end of the spring by separating about three to four coils of the free end of the spring and booking the mass to those coils. Let the mass suspend from the spring until it has reached equilibrium. D 2. Hold the ruler vertically next to the mass with the centimeter side closest to the mass. m: You will need to support the ruler while using the stopwatch with the same hand. If the mass does not hang low enough to rest the ruler on the floor, try placing your lab kit box under the hanging mass to be used as a base. If the mass touches the floor when hung on the coils try using a higher counter top. If there is no higher counter top available try using the top of an open door. You want to make sure that you can displace the mass at least 6 cm from equilibrium and not have the mass hit the floor. Be careful and use extra tape for support. Ensure the pencil is stable before hanging any mass on it. Wear safety glasses. E 3. Observe where the top of the mass lines up with the ruler when it is at equilibrium (at rest]. [:4. Displace the mass 2 cm from equilibrium by pulling it down until the top of the mass is 2 cm lowerthan when it was at rest and release it. Observe the resulting motion. E 5. Use the stopwatch to measure the amount of time it takes for the mass to make N oscillations. Let the mass go through a few oscillations before starting the stopwatch. Record the number of oscillations you choose to time in Table 1. (Between 10 to 20 is a good number to reduce error.) [6. Repeat Step 5 until you get a consistenttime reading. Record this time in Table 1, for Trial 1. [7. Run two additional trials and record the times in Table 1, Trial 2 and 3. [3. Repeat Steps 4 - 7 using 3 cm. 4 cm, and 5 cm values. Part 2: Changing Mass 1. Set a pencil on a surface. such as a table or counter. perpendicular to the edge of the surface with the eraser end extending approximately 3 cm o ol the surface. 2. Secure the pencil to the surface with masking tape. 3. Suspend the spring from the pencil by the circular loop of the spring. 4. Hang the 50 g mass on the end of the spring by separating about three to tour coils of the free end of the spring and hooking the mass to those coils. Let the mass suspend from the spring until it has reached equilibrium [not moving]. llllllllllllllllllllllllllllllllll 5.

Use caution and extra tape for support. Ensure the pencil is stable before hanging any mass on it. Wear safety glasses. Figure .1: Step 12 reference. 6. Observe where the top of the mass lines up with the ruler when the spring rests at equilibrium (no movement). 7. Displace the mass 3 cm from equilibrium by pulling it down until the top of the mass Is 3 cm lower than when It was at rest and release it. Observe the resulting motion. 8. Use the stopwatch to measure the amounlof time It takes forthe mass to make N number oscillations. Record the number of oscillations you choose to time In Table 2. 9. Repeat Step 8 until you gela consistent time reading. Record the time in Table 2, Trial 2. 10. Run two additional trials and record the times in Table 2, Trial 2 and 3. 11.Repeal Steps 4 1I'.t for the 100 g mass. and the combined 150 g masses. 12. Weigh the steel bolt and enter the mass In Table 2 between the parenthesis. Attach the steel bolt to the end of the spring as shown In Figure 4. Extend the end of the coil and start to wrap It around the thin part of the bolt Just under the head, similar to putting a key on a metal key ring. Once 1 - 2 coils have been wrapped around the neck of the bolt and It is secure, move onto the next step. 13. Repeat Steps 4 - 1D for the steel bolt. If the displacement is too large, reduce It by 1 cm until a smooth osclllatlon ls observed
