Angle of the Plane (degrees) Mass of the cart (kg) 10 0.2719 Data Point Speed (m/s) Distance (m) Height (m) PE (J) KE (J) Point 1 0.234 0.149 0.026 0.0694 0.00744 Point 2 0.014 0.1644 0.029 0.0774 0.000027 Point 3 -0.203 0.1527 0.0265 0.0707 0.0056 Summary 1. The kinetic energy of the car increases in the order of point: 2(negative velocity) --> 3 (velocity=0) --> 1(positive velocity). The position vs time and velocity vs. time graph indicates that there is a changing negative velocity. After releasing the car, the car accelerates down the incline thus, increasing the kinetic energy. When accelerating down the incline, the potential energy (mgh) is transferred into kinetic energy As the kinetic energy of the car increases, the potential energy of the car decreases. The potential energy increases in the order of point: pt 1--> 3-->2 2. The total mechanical energy has a small deviation between each respective point (.0768, .0774, .0763 This indicates that the energy is conserved, thereby adhering to the law of conservation of energy.
