KE1 + GPE1 = KE2 + GPE2 (2). Dissertation - Discussion. If the lower edge of the ramp is not level, ask your lab instructor for help with this adjustment. This preview shows page 1 - 2 out of 5 pages. For the first task, we simply observed that during the first downward motion of the glider the total energy remained constant throughout the motion. Conservation of mechanical energy lab report conclusion. Review student answers to gauge their depth of comprehension. Results and Conclusion: - For task 1: we have found that total energy remains constant during the motion of the glider until the collision occurs. IntroductionWhen a body moves, some things—such as its position, velocity, and momentum—change. We know that the law of conservation of energy says that energy can never be created or destroyed, so what happened? Dthe sphere moves from the end of the ramp to the point where it touches the table is given by. We compressed the spring by moving the glider to a new stop position, 2 cm beyond.

V 2at the end of the ramp is. The motion of a pendulum is a good demonstration of mechanical energy conservation. There are only two forces influencing and acting upon the pendulum bob, they neglect air resistance which is very small even considering the small size of the pendulum. V 2exp, the velocity of the sphere as it leaves the ramp. Supporting ProgramVU Bioengineering RET Program, School of Engineering, Vanderbilt University. A working understanding of Newton's laws and flow charting. The second part of the lab was supposed to demonstrate conservation of mechanical energy by bouncing the weight and measuring the high and low point. The graphs drawn on the data sheets clearly show the law of conservation of energy which states that energy is never created nor destroyed. Second and third readings show that the coefficient of restitution decreases with increasing the height. In real life, much of the mechanical energy is lost as heat caused by friction. For this lab, you would need to collect various toys (slinkys, plastic jumping frogs, poppers, yo-yos, tops, wind-up) and ask students to illustrate/write about the kinetic and potential energy of the toys. The mass of the spring and the mass hanger and put this data into your lab report. Dissertation - Abstract. However, these contents do not necessarily represent the policies of the NSF, and you should not assume endorsement by the federal government.

Also try the three differently shaped skate parks. We repeated these steps three time to produce a table of results. The total energy is a result of the summing of the given scores of two energies. A final source fo error would be related to human factors. Energy Skate Park - Using an online simulation set at a skate park, students make graph predictions before using the virtual laboratory to create graphs of energy vs. time under different conditions. Dissertation - Results. For intermediate values, collision will be inelastic with glider in motion after the collision. Explain that energy lost to friction is really transforming kinetic energy at the macroscopic level to kinetic energy at the atomic level. Once you have measured the position of the dot, draw an "X" through it, and label it so that you will be able to distinguish it from later marks. What is the kinetic and potential energy when the rock has fallen 10 m? The student is expected to: - (B) investigate examples of kinetic and potential energy and their transformations; - (D) demonstrate and apply the laws of conservation of energy and conservation of momentum in one dimension. In the discussions to follow, we will use the approximation that transformations are frictionless. In case of 0 the glider will be at rest after collision, in case of 1 the collision will be elastic. BL] Be sure there is a clear understanding of the distinction between kinetic and potential energy and between velocity and acceleration.
