Trebuchets and cars
This project called for two very different, yet similar devices, both with the same basic idea, move object A from point A to point B. One very violently, and one slow and steady
Take your pick
Slow and steady: The slow and steady option is a solar powered car. It can go only 0.25 m/s but can travel at that speed for as long as we need, for this test we took it to 5 meters. It carried 250 grams of pennies, weighting 500 grams alone.
Velocity is constant, .25 meters per seconds, It did manage to speed up slightly but we cant explain that. This is represented on the distance over time graph.
Total energy: Total energy constantly increases as more is constantly added to the system.
Potential energy: We found this energy by multiplying the energy the sun gives to a square meter of land, and multiplied it by the area of our panels.
Kinetic energy: Because mass and velocity didn't change, kinetic energy stayed the same at 0.0234 J.
Thermal energy and friction: Thermal energy 65.984 J. This was found by subtracting kinetic energy from total energy.

Violent: The trebuchet is the fast way from point A to point B, with force. With 2 arms, a boom, and a base, it is stable. The legs hold an axle that attaches to the arm.
PEspring: Is energy stored as compression or stretching. Our trebuchet used PEspring to launch the projectile. Ours lead to 14.15 jouls
Velocity: The velocity our trebuchet reached was 13.85 meters per second, or just over 30 MPH.
KEBall: The kinetic energy of the ball was found to be 2.16 joules.
Energy conversion: The percent of energy converted was 24 percent.

During this project, I learned how to work with those with outlandish ideas, and how to make them feel like they're helpful. I feel I should learn to apply myself more as I feel most of the work feel to one person, Thank you Evan, we couldn't have done it without you. I would also like to thank Anderson for his generosity. Thank you to Stalin for helping me to write this in English, not German.
