Alternative Energy Vehicle

Over a span of 5 weeks my group was assigned to make two different projects. We were set into the maker space after brainstorming our ideas. We built and tested our prototypes until we find the one. After we would end up back in the classroom for even more testing and analysis.

On our first day we brainstormed ideas for what we should do, Mr. Williams then told us it didn't have to be a car. So that's when we decided to be more creative than everyone else and make a zipline. We all came up with different ideas of how we should design it to safely transport 2 rolls of pennies. We made up all our minds and agreed on a ski lift design but instead of it bringing you up its bringing you down.

On our first day in the makerspace we went straight to work. We got two planks, one plank long and a very short plank. We cut them to the exact lengths we needed them at. After that we grabbed the rest of the materials we needed. We started screwing the nails from the legs to the base. The next day we added hooks to the top of each leg so that we could put the line in between to hold the cart. we tested the sturdiness of the base to leg. It seemed great. once all the nails were done we measured the height for when we needed to do calculations. The last we got in the makerspace we used all of out time wisely. We finished the cart and added the fishing line. We then tested how it would work at 5 meters away from each other.

After the makerspace we went back into the classroom to do calculations and make our last edits. Inside we realized their was too much weight and the bases couldn't stand straight. So we added a string from the legs to the ground and added tape. We then added all the times and heights into our equations to get the calculations.

Kinetic Energy - (KE =1/2mv^2) - the energy due to motion

• For our project we determined the KE at all meter marks

• Meter 1 (2.04J), Meter 2 (2.77J), Meter 3 (2.77J), Meter 4 (1.77J)

Thermal Energy - (TE =Total E - PE - KE) - the energy lost to heat

• For our project we determined the TE at each meter mark

• Meter 1 (-0.244J), Meter 2 (0.046J), Meter 3 (0.546J), Meter 4 (1.546J)

Total Energy - (Total E = PE+KE+TE) - the addition of all energies

• For our project we determined the Total Energy

• The total energy is 3.316J

REFLECTION

Over the span of the project i felt like i did well on two things. Being able too see everyone's strengths in the group to help figure out who does what and also being able to do the calculations for the team. But the were things i needed to work on for myself. My leadership skills were not to great. I wasn't always there for my group and make sure they are getting their job and i also went off task a lot and socialized more than i should have.
