Though the apparatus was meant to mimic a frictionless surface with the use of an air blower, some friction was still present, as the air blower on the apparatus was not as strong as it should have been.Confidently Integrate Computational Thinking into Any Lesson with Blockly This is due to experimental error in the form of random error, since it is not consistent between trials. However, an average percent difference value of demonstrates that this was not the case. In an ideal situation, the percent difference between these two values would be as all potential energy would be converted to kinetic energy.

In this experiment, potential energy was supposed to decrease as the mass attached to the pulley fell, while the kinetic energy was supposed to increase.

Trial Number Percent Difference 1 2 3 4 5 6 Average Table I: Percent Error Sample Calculation: percent in KE change in in x x This experiment demonstrates how potential and kinetic energy can be interconverted, with the overall amount of energy remaining the same. The expectation is that the change in potential energy will equal the change in kinetic energy, thus supporting the law of conservation of mechanical energy. hanging The change in potential energy of the system was calculated as follows: E 0.041 J The percent difference values between the kinetic energy and the potential energy for each trial are shown below. The initial and final velocities in each trial were calculated using the measured time values as follows: 0.63 0.36 These values were then used to calculate the change in kinetic energy of the glider and the hanging mass, as follows: hanging These changes in kinetic energy of the components of the system were then added together to get the total change in kinetic energy of the system.

To demonstrate the calculations, values from trial 1 will be used as an example. Analysis For this experiment, all calculations were done in an Excel spreadsheet. With these values, the kinetic energy of the glider, the kinetic energy of the hanging mass, the kinetic energy of the entire system, the potential energy of the hanging mass, and the percent error of the experimental values could be calculated. The computer program connected to the photogates gave values for time. The glider was then pushed and let the air track and hanging mass take the glider past the two photogates. The weights were applied to the end of the pulley (hanging mass) with the values that were stated in the lab manual. All of the above mentioned equipment, excluding the computer is seen in Figure 1 in the lab manual. Procedure The equipment used for this lab consisted of: a two meter horizontal air track, a glider, a pulley, two photogates, masses, an air blower, a Pasco 850 Universal Interface system, and a computer with Microsoft Excel and Pasco Capstone. In this instance, kinetic energy at a specific point was calculated subtracting the initial kinetic energy from the final kinetic energy ( The total kinetic energy is found adding the kinetic energy of the glider and the kinetic energy of the hanging mass hanging The total energy of an object is the summation of kinetic energy and potential energy. Kinetic energy is the product of 0.5, the mass of the object, and velocity squared.

Potential energy is found multiplying the mass of an object acceleration due to and the height of the object from the ground ( E where and indicate final and initial position). The experiment conducted demonstrates the connection between kinetic and potential energy and to see that with a frictionless system, energy is to be conserved.
