Our Rube Goldberg Machine
In our Rube Goldberg machine we were trying to pop a balloon filled with pop rocks while raising a skittle to eat. We tried todo this by popping a balloon with a box opener and while lifting up a skittle by using a series of ramps, simple machines and energy transfers. First the small jawbreaker goes down a ramp into a screw. Then it goes down a ramp and it hits a larger jawbreaker then it pushes a lever. Which then pushes another large jawbreaker which then goes down another ramp and into a pulley which raises an skittle and drops the jawbreaker out of it. Then the jawbreaker goes down two more ramps and it pushes a knife which then goes and pops the balloon and the pop rocks fall out of it into sprite which makes them fizz.
Concepts
Force: Force is a push or a pull. The formula for force is force = mass x acceleration. Newtons (N) is the unit for force. Below, where the steps are explained, you can see how we used force in our project.
Potential Energy: Potential energy is the energy stored in an object due to its position. The formula for potential energy is PE=mass x gravitational acceleration x height. The unit for potential energy is Joules (J). Essentially potential and kinetic energy equal each other. Below, where the steps are fully explained, you can see how we used potential energy in out project.
Kinetic Energy: The kinetic energy of an object is the energy which it possesses due to its motion. The formula for kinetic energy is KE=1/2mv^2. The unit for kinetic energy is Joules (J). Essentially potential and kinetic energy equal each other. Below, where the steps are explained, you can see how we used kinetic energy in our project.
Mechanical Advantage: Mechanical advantage is the ratio of the force produced by a machine to the force applied to it. The equation for mechanical advantage ideal is MA=d effort/ d load. Below, where the steps are explained you can see how we used mechanical advantage.
Velocity-The speed of an object in a given direction. The equation for velocity is v= change in d/ change in t. Below, where the steps are explained you can see how we used velocity.
Acceleration- The time rate of change of velocity with respect to magnitude or direction. The formula for acceleration is a=change in v/ change in t. Below, where the steps are explained you can see how we used acceleration.
Work- The transference of energy that is produced by the motion of the point of application of a force. The equation for work is w=fd. Below, where the steps are explained you can see how we used work.
