Used 2003 Hyundai Elantra GLS Sedan Used
Our assignment
We Were prompted to make a self propelled vehicle that could carry 100 pennies 5 meters in the most efficient and effective way. At first we planned to use the spinning of a fan to spin the wheels to propel the car. We began to build the car. We used Lego wheels on our car so because we didn't want to damage the wheels we had to use a very small axle. Since we had a small axle we couldn't put a fan on our car because it would snap the axle. We had to scratch the idea of using the fan. We decided to run our vehicle down a ramp to propel it. We did many trial and error tests to calculate the perfect height on the ramp to cause the car to stop at exactly 5 meters. Eventually we found that when our vehicle was 35 cm off the ground on our ramp it typically went 5 meters.
Content
Distance vs time: In our distance vs time graph we have time on the x axis because its the constant in the situation. Distance is on the y axis. Our graph is displayed in the slides presentation.
Velocity: Distance in meters the car travels in one second.
PE: The Amount of stored energy an object gets with the force of gravity or any other source. Our cars potential energy is gained by the height of our car compared to the distance of the ground.
KE: The energy that's present during movement. Potential and Kinetic energy always cancel each other out. The Kinetic and Potential energy will always be the same total energy when added together.
Thermal energy: The energy that is created due to friction. This takes away and absorbs kinetic energy into heat.
Friction:

Reflection
I think i did well to try to keep our group on task and focused. Me and my teammate Ethan worked very well together and we think it showed very well in our slideshow. We did a good job of selling the project professionally and making the most of our slightly lackluster propulsion method. Me and our group split up our work evenly and all got it done. I made extra efforts to make our slideshow by spending extra time to animate and professionalize our presentation.
In our group I could have stayed more focused and gotten teammates to contribute more instead of getting off task. As my teammates got distracted it often became hard for me to always stay on task like when a person from a different group would try to mess with our group by shutting off my Chromebook it became hard to always stay focused when i had to be way of people around me. I also could've started helping with other group members work once I finished mine. After I finished my work i often stopped and took a break where I should've continued working.
