Angle of the Plane (degrees)Mass of the cart (kg)100.2719Data PointSpeed (m/s)Distance (m)Height (m)PE (J)KE (J)Point 10.2340.1490.0260.06940.00744Point 20.0140.16440.0290.07740.000027Point 3-0.2030.15270.02650.07070.0056Summary1.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 changingnegative velocity. After releasing the car, the car accelerates down the incline thus, increasing the kineticenergy. When accelerating down the incline, the potential energy (mgh) is transferred into kinetic energyAs the kinetic energy of the car increases, the potential energy of the car decreases. The potential energyincreases in the order of point: pt 1--> 3-->22.The total mechanical energy has a small deviation between each respective point (.0768, .0774, .0763This indicates that the energy is conserved, thereby adhering to the law of conservation of energy.
