Conservation of Mechanical Energy Essay

Background kinetic zip is said to be the nada of drift. Kinetic push crapper be defined through this equationKE=12mv2 (equation 1)Where m is the mass of the objective lens in action, and v is the pep pill of the moving object.Potential energy is the energy associated with the forces that depend on the position of the object. However, there are specific types of authorisationity energy and in this lab we exit consider gravitational potential energy. Gravitational potential energy is the energy possessed by the objected receivable to earths soberness. This can be specifically defined by the equationPEgrav=mgy (equation 2)Where m is the mass of the object, g is the acceleration due to gravity and y is the height of the object.With these energies defined, add energy of the system is the sum of its kinetic energy and potential energy at any point in time.Total energy= kinetic energy+ potential energy= uniformTherefore the law of conservation of energy is defined as the tota l energy is neither increased nor decreased in any process. zipper can be transformed from one to another, and transferred from one object to another, only the total amount remained constant, therefore conserve. Procedurethe procedure of this lab involves a dynamic trail launched up a track towards a motion sensor. Once the equipment is set, measure the angle and record. Then use the coiled ring launcher to launch the dynamic cart by transferring kinetic energy which in turn sets the cart into motion along the cart. The cart will reach a maximum height on the track out front it reserve direction. Collect the date of position and time by connecting the motion sensor to data studio which will record the results as the cart as the cart is in motion. Graph position versus time and velocity versus time with the data collected from the motion sensor.ConclusionIn this test we observed that no energy was scattered in the system, even the energy was not keep. This can be shown by en ergy versus time graphs. In the theory the law of conservation assumes that there is no attrition, thus conserved energy. However, in this experiment we observed the friction that occurred between the wheels of the coaster and the track, and the wheels of the cart and the track. This friction explains how energy is not conserved and also due to a vitiated fraction of the systematic error that occurred in conducting the lab. This error can be shown in the uncertainty of the angle and the uncertainty of the position of the cart by the motion sensor. With this uncertainty taken into account, it can explain why the transmission channel was not horizontal. To conclude the experiment proves that there is no energy lost in the system due to the transfer of potential energy to kinetic, however energy is not conserved due to friction.
