Physical Science Lab - the motion of a stainObjectiveThe goal of this experiment is to develop a theory, which allows us to under protrude the motion of a marble. MaterialsWooden roller coaster, marble, ruler, timer, clamp, physics stand. surmisalIn this experiment, we are finding the Conservation of faculty. qualification is neither created nor destroyed. null is summed up into two different properties electromotive force zero and Kinetic energy. The rectitude of Energy states that Total Energy = Potential Energy + Kinetic EnergyOrEm = Ep + Ek Also, the equations for Potential energy and Kinetic energy are stated to get the Total Energy. They are respectively Ep = mghandEk = (m)v2 The Conservation of Energy states that energy is always constant. If potential energy increases then energising energy decreases and vice versa. In this experiment we positioned a marble testis on a wooden roller coaster positioned on a physics stand in the sixth hole. Throughout the experim ent, we used an electronic timer to reputation the time of the marble where it passed through the light beam of its clamp. We positioned the clamp at a certain point on the roller coaster and measured the withdrawnness from the marble to the clamp the height of the clamp and finally the time the ball travelled through the clamp. After we recorded these different figures we calculated the festinate of the marble from the given distance traveled and the time. We repeated the step 14 time, then proceeded to graph the reanimate and the height. Next, we took the measurements of position of the clamp, height, and speed and calculated the potential energy, the kinetic energy, and the total energy. Total energy calculated as mentioned before. Potential energy is taking the mass (m) which is 28.1g times gravity (g) which is 9.8 m/s2 times the height. Kinetic energy is one-half times the mass (m) times fastness (v2). Finally we graphed the calculated kinetic, potential, and total energi es of this experiment. For this theoretical result, the motion or speed of the marble will have different calculations. Also, the potential energy and kinetic energy of the marble will produce a mirror effectuate between each other respectively. From the result of the experiment, as the height of the marble increases the speed of the marble decreases at a slow rate.
