The purpose of this lab was to use a pendulum to observe the right of conservation of cogency, because pendulum motion is based glum 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 remains constant. This lab verifies this law using a pendulum and the following equations: K=(mv^2)/2, U=mgΔh, and TE=K+U. Based on these equations, the total energy of the pendulum should remain the analogous throughout its swing.
Experimental Process
The first thing that was done was the mint of the lump was taken. Then the length of the pendulum from the top of the string to the touch on of the ball and the distance from the detector 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 while the software recorded its distance from the sensor. The final tint was to plug the equations for potence and kinetic energy into the software so it could make a graph of the potential drop and kinetic energies of the ball and then 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.
Conclusion
likely and kinetic energy are inversely proportional. The ball scorch back and forth showed a good representation of their relation. As the ball swings up, the potential energy increases as the kinetic 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, order it on our website: Ordercustompaper.com
