Conservation of Energy Lab Essay - 1536 Words

FREE FALL AND CONSERVATION OF MECHANICAL ENERGY ABSTRACT Free fall is defined as the ideal falling motion of an object that is subject only to the earth’s gravitational field. To prove the law of conservation of energy, the free fall motion of an object can be represented through 3 different analyses; position of the object vs. time, velocity of the object vs. time, and acceleration of the object vs. time. It is observed in this ball toss experiment, at any point during the free fall period, the system contains the same total amount of mechanical energy. This amount is the sum of kinetic and gravitational potential energy.

Terrestrial Gravitation Acceleration, First Law of Thermodynamics and Centripetal Acceleration vs. First Law of Thermodynamics. Each of the experiments demonstrated the importance of the first law of thermodynamic and how its present on our daily lives. Therefore, reinforcing the importance of thermodynamics concepts and their role in our society.

Our calculations were based on Galileo’s ramp. Galileo hypothesized that a falling object would gain equal amounts of velocity in equal amounts of time, however, he was unable to test this theory, as he could not accurately measure an object free-falling through space. In order to rectify this, he attempted to slow down the objectsRead MoreEnergy of a Tossed Ball768 Words   |  4 PagesEnergy of a Tossed Ball Project PURPOSE: The purpose for the students of the Energy of a Tossed Ball Lab involved learning how to measure the change in kinetic and potential energies as a ball moves in free fall. Since there is no frictional forces working on the ball the total energy will remain constant and the students will see how the total energy of the ball changes during free fall. HYPOTHESIS: 1. The ball has potential energy while momentarily at rest at the top of the path. 2Read MoreLab Report Essay753 Words   |  4 Pagesï » ¿Beginning with science : 06 Matter and Energy Kevin Edwards.

Conservation of Energy Early in his career, Hermann von Helmholtz developed a passion for sciences that would impact society and make the world a better place. One of the best ways he contributed to the world of science was providing us with his research on the conservation of force. Hermann von Helmholtz uses the term ‘force’ in place of the term ‘energy’. During the time period, theories of conserving energy to better sustain our land was unfamiliar andRead MoreThe Findings After Testing Quantized Inertia On The Emdrive971 Words   |  4 Pagestesting quantized inertia on the EmDrive. The authors predicted that the thrust produced by the EmDrive can be explained assuming that the inertial mass of the photons is caused by unruh radiation. Multiple experiments took place in several independent labs, and produced results that were similar to the predicted values for thrust. The computations of the results did not sufficiently model wave oscillations in 3D, thus the authors recomme nd further testing in order to produce more accurate findings.
