Rube Goldberg Machine Research Paper

This part in the article made me wonder a little bit. My question is about the kinetic energy. Does the kinetic energy only cause heat energy and sound energy?

For my Rube Goldberg Project, my group and I decided to push in a soap dispenser that was on the wall. We created a five step process that had worked numerous times before, but sadly failed to work when presenting. Even though this happened, we had many steps that reflected motion, force, mass, friction, and transferring energy. Our steps were having a marble roll down a ramp, which landed on a metal casing that would propel it forward. This marble would hit some dominoes that were lined up in three rows and knock them all down. Two books were at the end of these lines, so they were to knock each other over and have one book land on a remote controller. This would press in the forward button, making a remote controlled car that was placed on top of a cardboard box advance forward and hit the soap dispensers button.

Which tended to be higher, the initial potential energy or the final kinetic energy? Why might this be?

The first flash video shows the outer part of the ear (pinna) that serves as the funnel catching the sound and the ear canal that carries the sound to the eardrum (tympanic membrane). The second flash video shows the eardrum that vibrates as the acoustic energy (sound) hits it, transforming the acoustic energy into mechanical energy. The third flash video shows the middle part of the ear, housing the Ossicular Chain (incus, malleus, and stapes) that moves as the mechanical energy is transferred to the chain from the vibration of the eardrum. The movement of stapes (last bone in the chain) causes the round window to move. The fourth flash video models the transfer of the mechanical energy into hydraulic energy within the cochlea as the round window vibrates with the stapes (from the Ossicular Chain).

Asier Marzo, who is from the Univeristy of Bristol in Britain and the Public University of Navarre in Spain, explained that they used ultrasound with a frequence of 40 kilohertz to move the object because sound waves are able to exert foce on objects.

Introduction Potential energy is energy stored in an object that gives it the capacity to do work or make things happen. Every object positioned above the ground had gravitational potential energy (Gravitational Potential Energy = mass x gravity x height), therefore when a ball (which has gravitational potential energy) is dropped, gravity pulls the ball towards the earth’s surface. The potential energy of the ball transforms into kinetic energy, or the energy of a moving object, as it falls (Kinetic Energy = ½ x mass x speed of object). Since the law of conservation of energy states that energy may be transferred but never created or destroyed, the kinetic energy in the ball has to go somewhere when the ball hits the ground. Therefore, the

The claim, which is the general statement of conclusion as of the result of an experiment, is the higher the height of an object the more gravitational potential (GPE) it has and the more work that will be done on the object hit. So in this case that higher the marble is dropped from the more

The instrument that we constructed to investigate different soundwaves and frequencies each mediums produce with was the vertical chimes. We changed the medium (materials) that the sound waves travelled through. The chime is made up of a newton ball, pebble, mothball and marble. Unlike the wind chimes we didn’t use wind to make the instrument play but we used a metal spoon to hit each individual materials with. This experiment was ran during class by using an app that recorded the frequency of the sound that the vertical chime was producing. We had many challenges on the way like recording the frequency with the app, controlling the variable and getting the results.

Dating back as late as the 17th century there exists accounts of musicians and scientists alike who managed to find ways to capture sounds. In many such cases, as with Wilhelm Weber in 1830 or Jean Duhamel in 1837, the purpose of capturing sound was to demonstrate, graphically, vibrational waveforms (Brock-Nannestad and Fontaine 2008). Yet, today, there exist numerous ways to record sound for the purpose of playing it back. A closer look at the history of sound recording unveils some remarkable designs, brilliant inventors, and devious machinations – when it comes to who should be taking credit for history’s advances in sound recording technology – all of which made sound playback possible. As we travel back in time to examine

The principle used in this lab was that energy is conserved. The total energy is distributed as either kinetic energy or potential energy. Kinetic energy is caused due to motion and potential energy is caused due to gravity. We used the following formulas to calculate kinetic and potential energy, and percent difference:

The only sound effect needed is when the great flood happens. The sound of the rain coming down pouring and water from the lake is splashing creating waves causing the kayak to move and rock a lot.

As displayed in figure 2, a substance requires kinetic energy greater or equal to its activation energy in order for it to change from its initial form to its product. The activation energy shown is one of the pathways that a reaction takes with respect to the pressure that it is subjected to. Consider that for a substance to change from its solid phase to its gas phase the bonds are all fixed in a position and when the particles have enough energy, they are able to

The ramp is the source of energy for the balls. Energy here is in the form of gravity, as the start of the ramp is elevated to and it provides potential energy using the formula, where m is the mass of the individual balls provided, h as

Sound is a mechanical wave that is an oscillation of pressure transmitted through a solid, liquid, or gas, composed of frequencies within the range of hearing and of a level sufficiently strong to be heard. It is produced when something vibrates causing its the medium (water, air, etc.) around it to vibrate as well. In common everyday speech, speed of sound refers to the speed of sound waves in air. Sound travels faster in liquids and non-porous solids than it does in air. In this experiment,

The second part consists of the gearhead, power generator, and flywheel. These components are use to convert the motion into useful energy.
