Catapult

The catapult is a machine that launches an object into the air by using sudden tension. When people launched catapults, the object that was launched forms a parabola to hit the target otherwise known as a projectile. There are forces that act upon the object such as gravity and initial velocity. To calculate where the object lands, people use the vertex form and the quadratic formula. The vertex form is y = a(x – h)2 + k in which a is equal to the slope of the parabola, h is equal to half of the

Cooper Crosby P.4 2/26/17 Catapults The physics behind a catapult can be a complex topic to grasp. But, when broken down, looking individually at their historical uses, design types, and related physics concepts, it’s surprisingly simple to form an opinion on which catapult design is most effective and why. These categories, when combined, define the uses, functionality, and effectiveness of the historical (and modern day) catapult. Catapults were originally developed in 399 B.C, and had derived

Catapults used to be a major part of war back in around 400 bc-885 Ad before they became useless but they were important because they could launch just about anything as far as it needed to go. Certain situations such as launching boulders over castle walls or hand grenades into an enemy's trench are all great uses that the catapult provides. When building a catapult it is a very precise task involving lots of time to make. The design is very important because it's based off how heavy the objects

There was a weapon was the siege engine called a catapult. The term catapult came from the Greek word "katapultos". A catapult was a large machine on wheels with a basket attached to a long wooden arm and a power source for hurling projectiles on the other.The first catapult however was invented around 400 BC in Greek town Syracuse. It was not the type seen so many times at our own wars in today's Society for Creative Anachronism. The first catapult closely resembled a crossbow. It was called the

Catapults were ballistic devices. It was invented by a man named “Dionysius the Elder” and created it around 400 BCE. Since then it was a key weapon in warfare. The way it works is that a piece of wood called the arm was connected to a cup shaped bowl but another name for it was a bucket. The bucket was meant for holding the object you wanted to launch. The objects people decided to launch whatever it was it was called the payload. The arm connected to the bucket is laid flat down and springs vertically

and test different weapons from those eras. I am finding out which shoots the furthest the crossbow, the catapult, or the slingshot and if I do not know how they work, I cannot compare them to each other so I decided to research this. My hypothesis is that the catapult will shoot the furthest and I think that I am right do to previous research by professionals. 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 might

Greek ballista, the catapult, and variations on the catapult design, such as the Roman onager and mangonel. The ballista's design was very similar to an extremely large crossbow with a guide chute to keep the projectile on path. A large ballista could launch an eight pound stone over 450 yards. It took two men to operate a ballista (Hamper). A standard catapult used the inconsistent strength and weight of men as a source of power. Groups of men had to work to pull down the catapult bar in order to

The problem that our catapult solves is that it launches object without the use of relatively dangerous elements, like fire and gas. Also catapults solve the dilemma of a achy shoulders, because without a catapult one would need to go out of their way to launch something. But with a catapult they simple need to pull back the spoon to create energy.

Anglo Saxons were. The Anglo Saxons made many technology development and their culture is very interesting and their stories everyone loves. First while they were not the first ones to try they were the first ones to build a successful trebuchet, catapult, and mortar. The trebuchet is a siege and defense weapon that uses a counter weight and a rope attached to a object. The catapult.ho is a defense weapon because they couldn 't get the height needed to reach over the castle walls. It uses a winch

the marshmallow as it flung out of the catapult and through the air. In this paragraph I will explain three main processes we went through while doing our catapult project. First, we built catapults out of popsicle sticks and rubber bands, this process was hard and took a while. We had to wrap the rubber bands around each popsicle stick to connect them, then we had to hot glue a cap to the top to hold the marshmallow that we would launch. Next, when the catapult was finally built we were ready to start
