A) The purpose of this contraption/invention is to create a Rube Goldberg Device to light a matchstick.
the Rube Goldberg Device potential energy occurs at the beginning of
the device, starting at the metal lever that is holding the car in
place. Kinetic energy is happening when the car is traveling down the
ramp. Chemical energy happens within the battery and heat is then
applied once the match is lit. To solve for kinetic energy you use the
equation: KE=1/2mv and to solve for potential energy you use the equation: PE=mgh. (Work Packet).
energy transfer that is included within our Rube Goldberg Device is:
kinetic, potential, chemical, and heat (thermal) energy. We are going
to be using a data table to keep track of our energy transfers within
this project. We are also going to be using equations to solve how much
energy is being transferred.
E) The final version of our project was running perfect the build day but not on actual test day due to faulty batteries. We found out earlier that the device burned through batteries easily and that might have been from too many test runs or from leaving the batteries connected. The device is extremely reliable with a constant source of power,but due to its energy need it would be wise to change the batteries every 15 runs or so. The construction of our device is steady and reliable,it will not break easily.
F) Although facing build challenges in the beginning due to a certain member thinking nails would work when he could have used screw. The final build was sturdy and performed extremely well. The first time we got to send the car down and hit the switch was a wonderful moment as it worked flawlessly and meant we could go home soon afterwards. We really liked how we could build the project ourselves and modify it to our needs. We would not suggest any changes to this project as it is a great learning experience in a fun way. Just being out of the classroom let us relax more. We enjoyed how we thought of the project ourselves,It really let us explore the possibilities of what to do and to execute the idea.
