Catapult Experiment: The Strength Of A Kinetic Band

Energy is a system’s “ability to do work.”(Elert) The unit for energy is joules. Some other characteristics of energy are that it takes numerous forms and that it is a scalar quantity.(Elert) The two types of energy are kinetic energy and potential energy. Kinetic energy refers to an object’s motion. This differs

In light of our final exam, the chuck a duck project, we are to learn about projectiles, trajectory, and the factors that affect these things.

There are two types of energy: kinetic energy and potential energy. Kinetic energy is energy possessed due to motion, and potential motion is energy which

The physics concepts associated with them are projectile motion, energy, momentum, forces , speeds, and distances. The kinds of catapults all use the same theme of accumulated tension, but acquire that tension in their own way, their own design. The Mangonel catapult for instance, is what most of us think of as the traditional catapult. A large wooden device with four wheels and a spoon that launches fireballs. The Mangonel stores energy much like a spring would, therefore, we use the equation PEspring = 1/2kx^2. The tension in the ropes and arms of the catapult when pulling on its long arm stores potential energy which is transformed into kinetic energy when fired upon.

I used two of the 6 inch pieces, one regular and one that I had cut to 45 degrees. I lined up the 45 degree angle with the edge of the 12 inch piece of wood and screwed it in. About 3 inches to the left of that I lined up the regular 6 inch to the angle of the 45 on top and screwed that in.Next, I did the exact same thing but mirrored it. Then, I took the remaining 6 inch pieces and put one at the front base (1) and one at the back base (4) of the catapult. One of the other pieces was the connector between the two 45 degree angle pieces (3) and the other piece was near the front of the catapult where upon releasing the arm of the catapult, the arm would hit causing the ball to begin it’s projectile motion (2). After finishing the basic structure I began working on the arm of the catapult. I drilled a hole about ½ inch from one end, no bigger than the metal rod I planned to use. After drilling the hole I drilled another hole and placed an eye hook about 3 inches from the other side of the arm.I then took a plastic cup and cut it in half and placed it right up against the hook on it’s left side. Doing this will close off the hook so I can squeeze the rubber band onto the hook and the cup keeps the hook closed and the band can't escape. There will be about an inch of wood sticking out past the end of the cup. To secure the cup a drilled a tiny hole and used a ½ inch screw. Then I simply pushed the metal bar through one

Did you know that various types of catapults were used by the Greeks, Romans, and Chinese? We took various different steps to construct our catapult and see how we can improve it. First, the catapult we made was made out of 11 popsicle sticks for the base and construction of the catapult and 26 rubber bands to hold them in place. The model of my catapult collapsed easily and fell apart. I believe that if we put in more time and work into the catapult it would’ve done wonders. Second, our catapult was tested for accuracy but sadly started collapsing downward and was lopsided. The catapult made 30% of the shots we fired into a platform that was 100 centimeters away, it made no shots that were fired into a platform that was 150 centimeters away,

My hypothesis was if I change the materials of the arm, then the pom pom will go father because popsicle sticks are too straight, and there are not enough bends. I accept my hypothesis because of the data from my experiment. This experiment showed that when I changed the arm of the catapult, the distance that the pom-pom traveled was farther. In the control catapult, the pom-pom traveled an average of 10.78 cm and the range of the data was 24 cm.

Have you ever wondered how a catapult works? We had to ask just that question when we were assigned a project. Where we had to create a functional catapult and graph the arc of the object shot from the catapult we created. In this essay I will discuss the history and mathematical concepts behind catapults. I will also include some fun facts.

“The Jim” is built from various wood planks, screws, eye hooks, bungee cords, and a copper pipe. The base of the catapult is made from two by four planks. This choice of material provides sturdiness and allows the base to be heavy enough, so that it would not fall over when launching. The planks are on the two inch sides, which provides more surface area to attach other parts, and are held together by screws. Two more two by four’s were screwed on vertically on opposite sides inside the base. These planks act as pillars, to which eye hooks are placed on the tops, that will hold the bungee cords in placed. Holes, with diameters that are relatively close to the diameter of the copper pipe, were drilled through the

What is Energy? Energy is what makes things go, run, move, and/or happen. There are 9 types of energy Potential, Kinetic, Electrical, Chemical, Nuclear, Thermal, Mechanical, Heat, and Sound energy. Soon I got in a group and we had an experiment on energy in bowling. Our Guiding question was, “What recommendations will you give to the Alley Cats to help them win the bowling championship?” Our Hypothesis was If a heavy bowling ball rolls on 4 textbooks, then it will have the greatest energy, giving it the greatest effect.

Kinetic energy is the energy of motion, however potential energy is the energy that is stored.

Trebuchet: Trebuchets are counterweight catapults. Balancing on its fulcrum, the trebuchet is loaded and counterweight are loaded. The “launcher”, for lack of a better word, is then pulled down so that the counterweight is at the top. Once released, the counterweight will pull the “launcher”up. It will in turn launch whatever it is loaded with.

According to Hyperphysics, the definition of kinetic of energy is: “energy of motion” (“Kinetic Energy”, 2013). The kinetic energy of an object is the energy it possesses because of its motion. The formula that represents kinetic energy equation

Introduction If you were in a raiding army in the Middle Ages, a catapult would come in mighty handy for taking down castle walls. So by now, you will know my project is about simple catapult. My reason why making this simple catapult was to show how to make a simple machine without pulleys and lever and things like them also I wanted to make a simple machine that can move things to one place to another. You need information because you need to know what they are how the actual catapult work and how the miniature catapults are alike and how the parts are alike and different and what parts do what. Scientific concepts or principles the catapult uses are angles, attitude, power, distance, and weight. I have never researched this in the past but

Energy is defined as” the capacity to bring about movement against an opposing force” (). The first form of energy is known as Potential energy. Potential energy is the stored energy that an object contains. For example, a bullet inside a gun has potential energy. Once the bullet is fired it gains potential energy to cause damage. The second form of energy is kinetic energy which is energy in motion. This form of energy relates to objects that are in motion. For example, a pitcher throwing a baseball, the velocity of the ball when thrown represent kinetic energy.
