Evidence of Work
Our objective was to create a vehicle that would go 5 meters. We did this by drawing out ideas that we thought could work and go 5 meters. From there we were able to come up with the design of taping two Tech Decks together with the pennies on each board and it slides down a ramp. But, after coming up with that design we ran into some conflict.
After our initial design failed we came up with a new design on the last day at the makerspace. This design consisted of the ramp that we used from our previous design and two nails on either side and 3 sets of 3 rubber bands linked together, the Tech Decks taped and rubber banded together, with the pennies taped on top of each board. Then, with this set of materials we essentially created a slingshot that would launch our passengers to their desired location.

Distance vs. Time: Distance vs. time shows how far an object travels over an allotted amount of time. Our vehicle traveled 3.3 meters in 2.2 seconds. *After gathering calculations we were able to get it to go the full 5 meters.
Velocity: The rate of covered distance in a given direction. Formula: v=d/t. Our vehicle had an average velocity of 2.2 m/s, the velocity for the first meter was 2.4 m/s, the second was 2.1 m/s, and the third was 2 m/s. Measure in meters per second or m/s.
Spring Potential Energy: Spring PE is the energy a deformed object has (ex. stretched rubber bands). The formula for sping potetial energy is is PEspring=1/2kx^2. Spring potential energy is measured in joules or J.
Gravitational Potential Energy: Gravitational potential energy is an object's energy due to its height. The formula for gravitational potential energy is PEg=mgh. Gravitational potential energy is measured in joules or J.
Kinetic Energy: Kinetic energy is the energy is the energy an object gains from being in motion. The formula for kinetic energy is 1/2mv^2. Kinetic energy is also measured in joules or J.
Thermal Energy: Thermal energy is energy converted to heat. The formula for thermal energy is TE= Etotal- PE- KE. Thermal energy is measured in joules or J.
Friction: Friction is the force acting against the direction of motion caused by a molecular collision. In our project it was seen when the vehicle hit the ground and the vehicle and floor rubbed against each other.
Spring Constant: Spring constant is the stiffness of a spring and the tendency to back to its original form. The variable for spring constant is K and its formula is the force exerted on the spring divided by the displacement of the spring. It is measured the the unit N/m. Our spring constant for the 3 sets of 3 linked rubber bands was 54.4 N/m.

Reflection
Throughout this project I thought I demonstrated some things very well, learned a lot, and improved in certain areas. I thought I did a great job being persistent and did not give up when things got tough or my group ran into some problems. I thought I improved upon taking charge and leading my group mainly in the constructing and testing process. I thought that I demonstrated persistence most during this project when our initial design failed. I immediately got back to the drawing board and came up with a design and when the new design faced problems I made changes that led it to go the full 5 meters.
I feel that I need to improve on including my team in what I'm doing rather than just doing a task by myself and letting them do whatever they decided to do. I also think I need to keep my head up more because there were several occasions during this project where I wanted to give up and stop making changes to out prototype. One of the things that made me feel this was were when we first came up with the slingshot design and numerous launches would go 2 meters or less and or not launch at all.
