This is the Rube Goldberg project that I made with my group. It took us 9 days but this is the only time we actually got it to work. It is themed around the fair which is why we have a ferris wheel, grassy fair ground, and trashed candy wrappers. We have also thought of a way to tie every step into the theme of the fair. There is a total of 10 steps in our machine that all lead up to ringing the bell at the end. The first is an inclined plane, the second a pulley, third a ferris wheel (wheel and axel), fourth a slide (screw), fifth a lever, sixth another pulley, the a second wheel an axel which is a carousel, seventh an inclined plane, eighth a hammer on a lever, ninth another lever and last the ringing bell.

During this project my group had to make multiple compromises which was hard but also showed how we worked together. There were people who were more selfish and wanted their ideas and others were willing to be flexible. It was a long process in trying to get this to work and we used many different methods for different steps using trial and error to find the best solution. We finally got it to work in this video. During this project I learned I could be flexible and I could be resilient and keep trying to find the right way to do things. When we were deciding what to make the theme of our project if there were themes other people didn't want i didn't put up a fight. Also when I made the tube I used many different methods to keep it from unraveling.
PHYSICS
Velocity: Velocity is the rate of distance traveled in a specific direction. You find velocity by dividing the change in time by the change in distance(V=change d/change t). The unit for velocity is meters per second (m/s). Velocity is demonstrated in our project by the marble going down the ramp. Acceleration: Acceleration is the rate of speed increase in an object. You find acceleration by dividing the change in velocity by the time (change in velocity/ time). The unit for acceleration is meters per second squared (m/s^2). Acceleration is demonstrated in our project when the marble accelerates down the ramp. Mechanical Advantage: Mechanical advantage is the ratio of how much less work you need to do because of a machine. You find mechanical advantage by doing force input over force output. You can find mechanical advantage in our ramps, levers and pulleys. Potential energy: Potential energy is the amount of energy stored in an object because of its relative position to other objects. You find potential energy by multiplying mass by acceleration due to gravity by height(PE=mgh). The unit for potential energy is joules. Potential energy is shown when our hammer is balanced in an upright position. Kenetic Energy: Kenetic energy is the energy an object possesses while it's in motion. The formula for kenetic energy is 1/2•m•v squared. The unit for this is also joules. Our project shows Kenetic energy when the hammer is falling. |
