Through out our whole Rube Goldberg their is mechanical energy, potential energy, electric energy, and kinetic energy. Our class worked on a Rube Goldberg Machine in groups. Our whole grade make a lot of Rube Goldberg’s and this one was Matthew and I’s.

This is our Rube Goldberg machine video

There was mechanical energy. For example, when I dropped the ball down the ramp and it was my actions that made the ball go down the ramp. This means that it’s mechanical energy. The definition of mechanical energy is in the physical sciences, mechanical energy is the sum of potential energy and kinetic energy. It is the energy associated with the motion and position of an object.

Their was also potential energy. For example, when the electric car hit the jenga blocks and it went up an jenga block staircase and hit an eyeball. The eyeball had to go down the ramp not up because of gravity. Another example is that when the marble got hit by a dominoe the marble went down a tape ramp and went down instead of up. The gravity makes the ball go down. The definition is, this potential energy is a result of gravity pulling downwards. The gravitational constant, g, is the acceleration of an object due to gravity. This acceleration is about 9.8 meters per second on earth. The formula for potential energy due to gravity is PE = mgh.

There was also electric energy. For example, when the domino’s hit the jenga blocks on top of a string which released the electric car by knocking the jenga blocks off the string. This made the car move because of it’s fan on top of it. The definition is Electrical energy is energy that is caused by moving electric charges. Since the electric charges are moving, this is a form of kinetic energy. The faster the electric charges are moving the more electrical energy they carry.

There was also kinetic energy. For example, when the domino’s were gaining energy to have enough power to hit the marble down the ramp without stopping in the middle. ANother example is when, the marble hit the domino and then went up a domino staircase. The definition is In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.

Steps

1. Drop marble down the ramp. (Mechanical Energy)
2. Go through the tubes. (potential energy)
3. Hit the dominoes.
4. The dominoes release the electric car. (Electric Energy)
5. The car hits the jenga blocks.
6. The jenga blocks goes up a staircase and then hits an eyeball
7. The jenga blocks hits an eyeball ball
8. The eyeball ball goes down a nok hockey board. (Potential Energy)
9. The ball Goes through the goal and hits jenga blocks.
10. The Jenga blocks go straight and then up a jenga block stair case.  (Kinetic Energy)
11. The domino hits a marble.
12. The marble goes down a ramp. (Potential Energy)
13. The marble hits domino’s that goes up a domino staircase. (Kinetic Energy)
14. The dominos hit a jenga block which hits a toy car. (Kinetic Energy)
15. The car goes down a ramp. (Potential Energy)
16. The car hits a mini jenga block.
17. Then there is a big line of dominos that goes up and up the toy golf course.
18. The dominos hits a Jenga Block hits a golf ball into the hole.

4/3/16 Today we finished our whole Rube Goldberg. We have worked on it for around 20 hours total. Also we got it on our 24th try. We changed our Rube Goldberg many times. Probably around 6 times.
