Pendulum Lab Report

Statement of Purpose: The purpose of this science laboratory was to use a pendulum to observe the right of conservation of cogency, because pendulum motion is based black these basic principals. Background/Theory The theory relevant to this lab is the law of conservation of energy. This law states that the resume energy in a system quells constant. This lab verifies this law victimization a pendulum and the following equations: K=(mv^2)/2, U=mgΔh, and TE=K+U. Based on these equations, the correspond energy of the pendulum should remain the analogous throughout its swing. Experimental Process The first involvement that was done was the mint of the lump was taken. Then the length of the pendulum from the unclutter of the string to the touch on of the musket twine and the distance from the sensing element to the center of the ball were measured. at one time those things were done, the ball was swung back and forth in front of the sensor spell the sof tware recorded its distance from the sensor. The final tint was to fasten the equations for potence and energizing energy into the software so it could make a graph of the potency drop and kinetic energies of the ball and then(prenominal) print the graph out.

Analysis The graph showing the potential energy is the opposite of the graph showing the kinetic energy. The total of the potential and kinetic energy is consistent every time. outcome likely and kinetic energy are inversely proportional. The ball scorch back and forth showed a good example of their relation. As the ball swings up, the potential energy increases as the kineti! c energy decreases. When the ball is swinging downwards, the kinetic energy is greater than the potential energy.If you want to get a full essay, roam it on our website: OrderCustomPaper.com
