Method for the collection of data

1. Set the apparatus as shown in the diagram above with one end of the spring clamped and coinciding with the zero mark of the meter rule (don’t attach the mass and the pan).
2. Attach the spring to the trolley and slightly pull the trolley to make it slightly taut, slowly release it to rest and record the actual length from the meter rule at the end of the trolley adjoining the spring (At this point the string with a loop at one end is attached to the trolley minus the hanging mass in a pan).
3. Add a 100 gm slotted mass on the trolley and then hang the 500 gm mass in a pan on the other end of the looped string.
4. Leave the trolley to come to rest and then record the final position of the trolley from the meter rule at the point where the spring adjoins the trolley.
5. Calculate the distance by finding the difference between the initial and the final mark.
6. Repeat the steps three times and then find the average breaking distance by dividing the summation of the breaking distances obtained by three after which you record the reading.
7. Repeat steps 1-6 for masses 200gms, 300gms in that order up to 1kg while recording your findings.
