Description
The task given to us for this project was to create a vehicle using alternate energy. My group then had to decide and brainstorm the best ideas and way to go about it. We decided to make a zip-line. The zip-line would be generated purely off of gravity. Next, it was time to build our project. We had around 5 days in the makers space in which we built the basket, cut the pipes, added stands, and connected the string. With only few minutes left, we finally got the zip-line to work!
We then had to make a slide show with all the graphs, modifications, and selling points for our zip line.
Another thing mentioned in the slideshow is the price of everything. One slide mentions the actual size of the project and the other mentions a life sized version. We searched up like products to find the overall price, making it as realistic as possible.
The first slide also shows a video of the zip-line working
Concepts
Velocity ~ The amount of covered distance going a specific direction: The highest peak at which the velocity hit was 2.67 m/s and the average of the overall velocity was 1.23 m/s.
Spring Potential Energy ~ The energy stored in an elastic object once put in motion: There is no spring potential energy in our project because there is no rubber bands
Gravitational Potential Energy ~ The energy stored in an object before falling/moving due to gravity: The highest potential energy is at the top of the zip-line. In our case, before the basket is dropped, the PE is 3.07 J
Kinetic Energy ~ The kinetic energy is the ending energy due to motion: Our kinetic energy was the highest around the middle of the 5 meters at 1 J
Total Energy ~ The overall energy of the object: There is never new energy added to the object, so the total energy remains 3.07 J at all times.
Thermal Energy ~ The energy lost during motion due to heat friction: The thermal energy gets higher as motion progresses start at 0 and going all the way up to 2.13. The basket then gets pulled back up so the thermal energy goes back down to 2.03
As mentioned before, there was no rotational inertia existent in our project because there were no working wheels being used
Reflection
This project ended up being very successful. We were able to be very creative and there were many steps needed to complete it. I thought it was a very good length, not too short, but not so long that we get project fatigue. I also enjoyed my group and overall had a lot of fun doing this project.
Other things that went well was how cooperative not only me but my whole group was. Everyone had their own work and did what they needed to do to complete our zip-line in the given timeline. I think I put in as much effort as possible and tried to make sure I was always helping out and doing my part. I helped plan out the blueprint, then contributed in figuring out which tools would work best for what. One thing that I always kind of lack in, is a lot of the building process. I can be super clumsy and don't trust myself with a lot of the tools. But I try to pay that off and participate in other needed things that may not involve power tools. I also then did a lot of work with the graphing and the slideshow.
One thing I could work on is my communication and vocalizing things better and with a better tone. Sometimes things I say may come off a different way than intended. So I think being more aware of how I say things and understanding how it may sound to other people is a new challenge that I am going to have to focus on fixing. Hopefully acknowledging this with help me to become a better group member next semester.
