Physics Lab Report Conclusion

Procedure B was the second part of the experiment which determined the work done along the horizontal. The two meter sticks attached to the wall were transferred in a long, flat, and smooth table inside the laboratory; without disrupting the stability, the reference was horizontally placed in the table. Using the same set-up in procedure A, the alternative object was positioned in a horizontal surface. There was a stronger connection between the spring balance and the yarn connected to the pouch which prevented the spring balance and the pouch from diverging when it was being dragged as part of the experiment proper. Chained with the spring balance, the supply pouch was pulled to a distance of one and a half meter (1.50 m) using a constant rate of motion for three times wherein the force exerted must be parallel to the horizontal surface. For every trial, the reading on the spring balance was also recorded.

After procedure A and procedure B were accomplished, the group started to compute for the work using the set of data gathered from the experiment. Further details for the computation will be shown in the Results and Discussion of this paper. To obtain a better grasp of the experiment, below are the experimental set-ups conducted by the group:

III. Results and Discussion

Tables 1 and 2 of the appendix showed the

The detailed calculations being done can be seen in the tables 3, 4 and 5 of the appendix. Since the applied force and the displacement were on the same direction, the angle being used to calculate the average work done for both vertical and horizontal displacements in all trials, was zero. The average work done along the vertical displacement resulted to 18.933 J which was approximately 19 J, while the average work done along the horizontal displacement resulted to 3.495 J which was approximately 3.5
