There is a Japenese doctor named Masaru Emoto and he studies the effects on water. He exposes water to a thought, either by writing a word or phrase on a piece of paper and taping it to the bottle, having people think a thought in the presence of the water, or having people speak to the water. After exposing it to a thought, he freezes the water, but not completely- just before the water freezes, it turns into a water crystal. Which looks like little bits of sand in the water. He then views the water crystals under an electron microscope so he can see the detail. He notices the shape of the water crystals changed depending on the thought they were exposed to. When the water is exposed to a positive thought, it looks like a pretty snow flake in the microscope. And when it is exposed to a negative thought, it doesn't even look anything like s crystal or snow flake. At least 70% of your body is made of water. Thoughts like this effect your body in positive and negative ways. If you think and say positive thoughts, you will be healthy, if you say or think negative thoughts, you will most likely be unhealthy.
Rube Goldberg CalculationsPhysics calculations:
First step- Velocity Velocity of first marble hitting ball barring= 2.43 m\s Second step- Conservation of Momentum When small ball baring that weighs .00352 kg with a velocity of .45 m/s hits bouncy ball that weighs .06334 kg gets a velocity of .025 m/s. Third step- Potential energy Potential energy of flower bag= 1147.8 J. Fourth step- Kinetic energy The kinetic energy of the marble that knocks down the soda can= 11.8 J. Fifth step- Momentum The momentum of the ball barring= .003 kg times m/s. Sixth step- Impulse/final momentum We used the impulse equation to figure out our final momentum of the triangular wedge flying through the air. Final momentum= 1.836 N. |

My partner Ellie and I decided to use a two liter bottle and conjoin the to two smart water bottles. On accident we cut off the tip of one of the smart water bottles. Mr. Heerschap told us that ruined our pressure chamber so we had to start the entire rocket over. Ellie and I began to build our next rocket. It had the same build as the last one, a two liter bottle connected to two smart water bottles. On the practice launch day however, our rocket exploded after it’s first launch. So, once again we had to start a new rocket. We both finally realized to trash our last idea and come up with a new one. My partner and I decided to build a rocket that had a two liter bottle attached to a long and thicker paper towel roll. After watching our rocket fail at exhibition, we realized the paper towel idea wasn’t that reliable either.
If we could start all over again, we would change a lot of things to our rocket ideas. We both agree we would only have one two liter bottle. Connecting many bottles together had too much glue involved and that turned out to be very messy. I would also have planned to work on getting a different nose cone. Our nose cone was a Styrofoam cone. If we bought a better one and worked on making it stay on the rocket it would have worked out a lot better than it did. One last thing I would change is our fins. They were very big and we put way too much glue on them to stay, the glue took very long to dry so they fell off at exhibition.
Looking back on the entire project, Ellie and I worked very hard on all 3 of our rockets even though each one failed in its own way. We kept a hard work ethic and tried as hard as we could to get things done. Both of us learned to launch a rocket off of the launch pad in approximately 13 seconds. Ellie and I both challenged our selves in making well-built rockets. We needed to work on other details though, We should have spent more time on our parachute and nose cone instead of the body of the rocket, Other than those mistakes, we managed to do a splendid job and I am proud of all 3 rockets!

The Physics Behind my Rocket There are many things that come into play with Newton's first law in a rocket launch. When the rocket is launched it will continue to fly in a straight line unless another force acts upon it. In our case, Tyrone was affected by both gravity and wind. The wind threw Tyrone off the straight path he was supposed to be on. Another thing that could have acted upon Tyrone as his fins. The fins on our rocket could have thrown him off the straight line he was supposed to be on. The gravity was the force that slowed our rocket down and eventually pulled it to a stop and allowed him to come back down to earth.
Our rocket was remarkably light for the size he was. His mass was a lot less than most rockets, meaning he was able to launch off the pad at a very quick speed. Heavier rockets like Dylan and Al's took an increasingly longer amount of time to launch from the pad. The lighter the rocket the faster it execrates off the pad in to the air. In our case our rocket was able to come off the pad very quickly but only stay flying for a short period of time. Newton's third law applies to our rocket because of it;s fins have equal balance on each side. On our rocket we decided to stick with three fins for lighter weight and to keep them equal in strength and opposite direction. The set Tyrone up for a straight easy flight. If the third law was not implied it would be easy to say that he would not have a very successful flight through the air. |
