## Build a Catapult

Of course there could have also been errors in this experiment, like human error and wind factor, but they were not as apparent the second experiment. This energy is stored in the launching device as potential, or stored, energy. The Romans eventually modified them to throw stones, making them more effective in seiges against walled Using this relationship assumes that the force constant is constant, or that moving the arms back 2 meters gives twice the force that moving them back 1 meter would do, which is most likely not correct, but close enough for a general assumption of the force to be made. If the goods and services are not up to the standard, consumers can use substitutes and alternatives that do not need any extra effort and do not make a major difference. Unlike a trebuchet, this mechanism is more direct. The underlying concepts and principles have a mathematical basis. There is also information on the Trebuchet.

You might need to repeat the test a few times to make your observations. Also, manipulating different data and combining with other information available will give a new insight. Students will also have the opportunity to tour New York City and take in all the city has to offer. These numerous safety features all have their own significance to the driver, as well as to the passengers. A sling may be used maximize throwing potential, but slingshot devices are not permitted. Secured two boards to the back of the triangle for support of the apparatus 3.

Average speed is how fast something is moving; the path distanced moved per time. At this point the ring which is connected to the sling and loops around the finger for support slips off and the payload is launched. Judging from models I have made and carefully experimented with, it is certain that the more powerful ballistas of the ancients could cast arrows, or rather feathered javelins, of from 5 to 6 lbs. The physics behind a trebuchet is fairly complex. By controlling the distance the arm can move, it influences when the projectile is released and therefore the launch angle.

Baseball was one of the sports that I have always had such a. Forces on Inclined Planes Notes should include: Defend: Dynamics is defined as the study of the effects of forces on matter. Our catapult was based on some aspects of the mangonel. Why does a person have tackle with such force and such speed to be able to bring down the runner, or why a baseball can be hit with such force off a bat to be able to hit a home run. To launch the payload the restraining rope is released. These potential problems may be related to the development of fuel cells, nuclear fusion as an energy source, and others. The framework can be applied to different scientific phenomena and can be used to investigate the behaviour of the building blocks of the universe, all elementary particles.

In the following I will talk about the process and materials used to make it and the science of the catapult. Physics deals a lot with forces, such as normal force, gravitational force, and frictional force. Using this relationship assumes that the force constant is constant, or that moving the arms back 2 meters gives twice the force that moving them back 1 meter would do, which is most likely not correct, but close enough for a general assumption of the force to be made. When we finished, I was in shock! When you prepare the catapult to launch, you add energy to it. Both catapults and trebuchets make use of gears and winces that transfer direct force, making it possible to store and build potential energy through repeated applications over a long period of time. Conclusion: Our first hypothesis was not accepted as correct in this experiment. The catch for holding the bow-string, and the trigger for releasing it, are fixed to the solid after end of the wooden trough.

## How Does a Catapult Work?

Quantum Physics, the study of the quantum world smaller than an atom. Assuming constant breaking force find: 1 the magnitude of the breaking force, 2 the time required to stop. Once the initial velocity is determined 2 simple equations can be used to determine time the bolt will hit the ground and the maximum range. In addition, it also helps to avoid activities and actions that will be harmful for the company in future, including projects and strategies. The Mangonel was capable of firing 1,300 ft. Now I feel like it was a success, and we did well. I'm glad I conquered it.

In the next section we will briefly discuss the onager. A trebuchet is a weighted beam that swings a sling carrying the projectile see for pictures. Therefore, it is necessary to block the new entrants in the industry. Well the next two trials went about 5 feet farther in only. How smoothly the wheels coincide with the floor will depict the amount of friction being created which as well connects back to acceleration. Will this make it fly higher, farther, both higher and farther or take the same path but maybe faster? The trials are also much more consistent than in the first experiment.

What is the tension in the rope? Then all of the energy releases at once, throwing the projectile. The rope was usually made of human hair or animal sinew. It explains the design, and the necessity for each part in the design. Both catapults and ballistas operate by storing tension, in either twisted rope or in pieces of wood that have been flexed. A stockroom worker pushes a box with mass 1 1.

I'm also really proud of our distance. Jan Yarrison-Rice Physics 101 5 April 2005 Physics in Sports When many people think of sports, the topic of physics doesn't always come to mind. In addition, alternatives should be related to the problem statements and issues described in the case study. Acceleration is the rate of which velocity is changing, the change may be in magnitude, direction, or both. Now that it's over, it was fun and much easier than I expected. The sling releases when a certain angle Î± is reached.
