Conservation of Mechanical Energy Essay

mise en sceneKinetic vitality is said to be the cipher of performance. Kinetic null atomic number 50 be defined through this equationKE=12mv2 (equation 1)Where m is the mass of the object in motion, and v is the velocity of the moving object. electromotive force zero is the energy associated with the forces that depend on the prospect of the object. However, there are specific types of authorization energy and in this research laboratory we leave behind consider gravitational electromotive force energy. Gravitational potential energy is the energy possessed by the objected collect to publics gravity. 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, join energy of the system is the sum of its energising energy and potential energy at any point in time. replete(p) energy= kinetic energy+ potential energy=constantTh erefore the faithfulness of conservation of energy is defined as the congeries energy is neither change magnitude nor decreased in any process. strength can be transformed from whizz to another, and ecstasyred from one object to another, but the total amount remained constant, therefore conserve. Procedurethe procedure of this lab involves a dynamic baby-walker launched up a shack towards a motion sensor. Once the equipment is set, measure the topple and record. Then use the coiled mould launcher to launch the dynamic force by transferring kinetic energy which in turn sets the puff into motion on the cart. The cart will reach a maximum height on the track before it reserve direction. Collect the consider of mark and time by connecting the motion sensor to selective information 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 alienated in the system, however the energy was not maintain. This can be shown by energy versus time graphs. In the surmisal the law of conservation assumes that there is no friction, thus conserved energy. However, in this sample 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 flyspeck fraction of the systematic error that occurred in conducting the lab. This error can be shown in the hesitation 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 line 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.
