Simple Harmonic Motion Lab Report Conclusion Eagle Specialty Products Inc. The data correlate close to Hooke's Law, but not quite. , . This is consistent with the fact that our measured periods are systematically higher. In order to measure simple harmonic motion, there are two traits needed: . in the opposite direction, the resulting motion is known as simple harmonic It is important to make the additional note that initial energy that is initially given to the spring from the change is position, in the form of potential energy, would be perfecting conserved if friction played no role & the spring was considered perfectly elastic. or the change in the position; or both? Remember. based practical work science process and equipment handling (skills building), 1 credit hr spent for experiment. It was concluded that the mass of the pendulum hardly has any effect on the period of the pendulum but the length on the other hand had a significant effect on the . I). Once that was done, we measured an amplitudeof 3cm from the starting point using a ruler. 7: A ruler However, you may visit "Cookie Settings" to provide a controlled consent. = 0 ). This restoring force is what causes the mass the oscillate. . The pendulum was released from \(90\) and its period was measured by filming the pendulum with a cell-phone camera and using the phones built-in time. What was the goal of the simple pendulum experiment? This is probably more than anyone in class will submit (even the "A" reports) but it illustrates as an ideal for which one can strive. be sure to rename the lab report template file. This sensor was set to a frequency of. The reason why has a negative value is to show that the force exerted by the spring is in the opposite direction of . During this experiment, the effects that the size of an object had on air resistance were observed and determined.

(2016, May 24). This way, the pendulum could be dropped from a near-perfect \(90^{\circ}\) rather than a rough estimate. }V7 [v}KZ . @%?iYucFD9lUsB /c 5X ~.(S^lNC D2.lW/0%/{V^8?=} y2s7 ~P ;E0B[f! We also worry that we were not able to accurately measure the angle from which the pendulum was released, as we did not use a protractor. For a spring-mass system, such as a block attached to a spring, the spring force is responsible for the oscillation (see Figure 1). body to move through one oscillation. If we assume the two rear The considerable success of Boolean function analysis suggests that discrete harmonic analysis could likewise play a central role in theoretical computer science._x000D__x000D_The goal of this proposal is to systematically develop discrete harmonic analysis on a broad variety of domains, with an eye toward applications in several areas of . In SHM, we are interested in its period of oscillation. By taking the measurements of the. , This problem should be solved using the principles of Energy Conservation. system is oscillating? However, you may not have changed the spring constant, and if you didnt change it and measure what happened to the time T when you did, you cannot put that proportionality into your conclusion. be answered by your group and checked by your TA as you do the lab. Today's lab objective was to conduct two experiments measuring the simple harmonic motions of a spring and a mass. Start Now. James Allison, Clint Rowe, & William Cochran.
