## Ballista Physics Case Study Solution and Analysis of Harvard Case Studies

They are the Ballista, the Catapult basic Catapult , and the Trebuchet. If these two vectors are added together, the magnitude of the sum. George the chief engineer of Edward I. By controlling the distance the arm can move, it influences when the projectile is released and therefore the launch angle. Sports are filled with physics that no one understands because we never take the time to ask why, sports are all about physics and the techniques we use to be great at a sport.

## What Are the Physics Involved in a Catapult?

The three different materials being used for the projectiles are a pencil, a bit of wood and a replica of an original Ballista bolt. Side view, with stone in position. Scalars and Vectors Physics is a mathematical science. For defenders the positioning upon the walls of a fortification would afford additional range to the weapon, and some were placed on pivoting frames to allow for quickly repositioning a shot. These were: Overarching Enduring Understandings: Students will uncover and use appropriate scientific models to describe and quantify the nature and interactions of matter and energy. Make the circle bigger and see who can adjust their launching technique to best fit the new conditions. But in other cases the catapult is made to full size but in this case it is made to a scale factor of 25% of its original size so that mightâ€¦ 2178 Words 9 Pages The days catapult before me.

And the shortest tail, which measured 13. How do the principles of physics effect your daily life? We learned a lot about motion and physics during the process. Now that the project has concluded, I feel proud. Tentative destinations include the American Museum of Natural History, the New York Botanical Gardens, and various laboratories at New York University. How do you think your change will affect the ball's flight path? When the force is applied, the projectile is accelerated to the end of the ballista, at which point it released with a velocity v and an angle q from the horizontal. Phythogoras was a Greek philosopher.

The main types of catapults are Utrecht, mangoes, nonage and ballista. As they use the catapult to launch lightweight cotton balls, students are encouraged to explore the variables that come into play and to explore the physics of projectiles. Early applications of physics include the invention of the wheel and of primitive weapons. During the trip students will meet with professional scientists at a variety of research, teaching and government institutions, learn about the nature of these careers, and see firsthand what goes on day-to-day at these diverse career sites. This weapon proved inadequate for their needs because it could only shoot arrows about 300 yards and it could not throw stones.

The following Science Buddies activity on the Scientific American website has all the information you need to do this science activity with your students as a fun classroom activity or at home:. A sling may be used maximize throwing potential, but slingshot devices are not permitted. Maybe you felt you needed to exert more force or work harder to bend the stick farther. Scoring: Each group will be allowed three launches. In reality math, science, and especially physics, tie into every aspect of sports. They were used as siege machines to surround and blockade a town or fortress from an army trying to capture it.

## Build a Catapult

Once upon a time our eyes were the only way for us to see the world. The Trebuchet was the primary target of many reconnaissance missions sent to burn them to the ground. Best alternative should be selected must be the best when evaluating it on the decision criteria. From the large galaxies, planets, etc to the small how proteins fold, atoms, etc physics plays a role. The bow-string was in the form of a broad band, with an enlargement at its center against which the ball rested.

Its primary use was to, as the name suggests, pierce enemy shields, since normal bows lacked the power to do so. Laid out three 2 m boards in a triangle, with corners overlapping, and secured them together where they crossed 2. Instead of having one arm that rotates through a vertical plane, it uses twin arms that move through a plane elevated above the horizontal to an angle of its crews' choosing. Enlarged view of the solid end of the sliding trough. In this model, five forces have been identified which play an important part in shaping the market and industry.

## What Is the Physics Concept Behind a Catapult?

Students should understand that there is a network of rules and relationships that determine what will happen in a given situation Students should understand that physics principles are applicable to their everyday lives Students should find that by studying the rules of nature, the beauty of natural world becomes more alive to them Overarching Essential Questions: 1. However, the problem should be concisely define in no more than a paragraph. Louis the Dauphin of France crossed the Channel with a large force and laid siege to Dover Castle making a lenient and incessant attack on the castle walls. A catapult relies on torque, which is a function of the length of the arm and the speed at which it moves, to provide angular momentum to the projectile. The experiment should be repeated and with a different hypothesis. It really helps grasp the topic of projectile motion. Rare and valuable resources grant much competitive advantages to the firm.
