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.
