Rube Goldberg Machine
Transcript of Rube Goldberg Machine
Our Rube Goldberg Machine
Our Rube Goldberg machine used energy transfers throughout the whole machine, because just about all of it was kinetic energy. It used four of the eight types of energy, excluding magnetic and nuclear. It took many, many attempts to actually do what it was supposed to do. the place where it kept on going wrong was when the retort stand (or the catapult) didn't fling the marble into the funnel, causing it to all go wrong.
Our Legendary Team has:

Kinetic energy is the energy of motion. There is usually some sort of potential energy before kinetic energy (gravitational, chemical etc.) We used kinetic energy in many contraptions, such as where the retort stand flings the marble into the funnel. Kinetic energy is the most frequently used type of energy used in a Rube Goldberg machine.
Sound energy is probably the second most used energy, because most of the kinetic energy goes into kinetic energy, (which is an energy transfer) and some of it goes into sound energy.
Gravitational energy is occurring everywhere, if it wasn't, then the whole Rube Goldberg machine wouldn't work.
Heat energy is frequently used in the Rube Goldberg machine, where marbles cause friction on the object they are rolling on.
Light energy is not used in this Rube Goldberg machine, but light energy is pretty self-explanatory: It's when something emits light.
Potential energy is an energy that is waiting to be set off, for example, a ball on a table. The ball has gravitational potential energy, then when it falls, it has kinetic energy. There is usually a type of energy that is causing the potential energy, like gravity in that example. Potential energy is used a lot in our Rube Goldberg machine. It is usually not moving, or doing anything. In our Rube Goldberg machine, we use potential energy everywhere, whether its dominoes standing, or a marble waiting to be released.
Chemical energy involves the use of chemicals (obviously) to move around and get transformed into other types of energy, for example, batteries, or food you eat getting transferred into kinetic. Our Rube Goldberg machine does not use any chemical energy.
Electrical energy is when a type of energy is transformed into electricity. Our Rube Goldberg machine doesn't involve electrical energy.
Magnetic energy is the energy used with magnets, having a negative charge and a positive charge. Our Rube Goldberg does not feature any magnetic energy.
Nuclear Energy is energy emitted from nuclear radiation, like the sun and nuclear fuel rods. We definitely could not do this type of energy in our Rube Goldberg machine.
History of Rube Goldberg
Rube Goldberg (Reuben Garrett Lucius Goldberg) was a famous cartoonist, sculptor, author, and, most importantly, an inventor. He was a cartoonist for a lot of newspapers in America, and he made the Rube Goldberg machine. He started off by making these drawings, in which he thought was silly, yet those silly drawings made him famous.
The Law of Conservation of Energy
The law of conservation of energy is a law which states:
'No energy can be created or destroyed'
This means that there was always the same amount of energy in the universe, even from the very beginning-just in different forms. For example, before they had found out about electricity, the energy was in fossil fuels, then they found out about burning it down to heat water so the steam could turn the turbines, to turn generators, to make electricity for your home.
William Ross State High School develops highly successful students. Our community embraces personal development, acknowledges all achievements, shares all successes and positively supports all. Our school rules are Be Safe, Be Engaged and Be Respectful. Our supervising teacher is Miss Wescombe and she has helped us all of the way through the project.
Engineering and Design Process
1. Define the process
2. Do background research
3. Specify Requirements
4. Create alternate solutions, choose the best one and develop it
5. Build a prototype
6. Test and redesign as necessary
7. Communicate results
Some key assumptions were when making our Rube Goldberg machine were:
1. Law of conservation and energy.
2. Laws of Gravitational energy.
3. Laws of heat energy
4. Laws of kinetic energy
5. Laws of potential energy
6. Laws of nuclear energy
7. Laws of light energy
8. Laws of sound energy
Energy transformation is when one type of energy is transformed to a different type of energy. So, basically, they are everywhere. Almost Everything you do involves an energy transformation.
Energy transfers are when an object gives off its energy, but the same form of energy. The difference between an energy transformation and an energy transfer is that an energy transformation is when an energy is converted into another type of energy.
