Catapult Performance Based Assessment

This report shows the effects of weight distribution has on the flight distance of a paper airplane. Just like with real airplanes, paper airplanes rely on aerodynamics to get the airplane to fly, although, they may not look or fly the same they use the same. Changing the postion of where the weight is distrubuted on a paper airplane can affect the planes ability to fly as far.

The aim of this report is to analyse my overhand volleyball serve from a biomechanical perspective and compare it to an elite athlete’s overhand volleyball serve. Biomechanics is the sport science field that applies the laws of mechanics and physics to human performance, in order to gain a greater understanding of performance in athletic events through modelling, simulation and measurement. It is also necessary to have a good understanding of the application of physics to sport. In volleyball the applications of summation of forces, projectile motion and balance and stability have a major influence on the success and accuracy of an overhead serve.

“Fire!” I yelled as I pulled back the arm of the catapult, and quickly releasing it to have the marshmallow soar through the air. In this paragraph I will be writing about my catapult, and how far it fired, and also the accuracy, and finally how I built it. First, I had to construct my catapult we e were each given 16 rubber bands and 11 popsicle sticks. It was very challenging to tie the rubber bands to the popsicle sticks because there was a special way to tie the rubber bands, but I finally triumphed, I got all my rubber bands tied on. I figured out that if you tied the rubber bands to tight your catapult would start leaning and that’s what happened to mine, but if you tied them to lose your catapult would collapse. Second, I had to test

When we think of catapults we usually imagine them firing at castle walls during the medieval times, or standing in the background of a large army clashing with another in an action movie. However, catapults have a long and intricate history that twists and binds with our own, dating all the way back to 399 B.C. First documented by the Greek historian, Diodorus Siculus, in the form of an early design for the Ballista (type of catapult). Catapults were a staple for siege warfare all throughout history. The catapult was used by many different cultures, notably the Greeks, Roman, and Chinese in siege warfare; also

After all of the groups finished SketchUp we had to build a .33 scale model of the trebuchet we designed. Our group was way behind so there was not enough wood for us to build our model.

The trebuchet catapult was one of the oldest catapults ever used in war. It's projectiles were mainly heavy rocks or sticks. When launched, this catapult could deal enough damage to knock down buildings, walls and other catapults. The trebuchet was designed on a T shaped frame with a long staff in the middle and another across the top. One end of the top shaft had a counterweight and at the other end was a basket that held the projectiles.

The Romans, finding the ballista difficult to construct, simplified the design and created the onager. It had one arm instead of two, and is what is most commonly identified as a catapult today.

Performance analysis in sport is the investigation of actual sports performance or performance in training which can develop an understanding of sports that can inform decision making by seeking to enhance or improve sports performance (O'donoghue, 2010). So, performance analysis is very important for every sport because it can help to improve performance for players and teams. In performance analysis, there have a few types of analysis that can be use such as notational analysis, biomechanics and motor control (Bartlett, 2001). In addition, it also can be use to analyse the match in term of tactical and technical. According to Teodorescu and Urzeală (2013), performance analysis can help players to improve their skill and develop new strategies

First in the design process was developing the concept solutions. The Catapult and the Side Catapult (II & III in Fig. 1) were a classic design that had potential to be modified with a string pull trigger. The Spinner and the Shooter (I & IV in Fig.1) resembled the design of toys that shoot a foam disc similar the competition projectile. Our Datum for the decision matrix (VI in Fig.1) is a ramp with a spring-loaded striker to propel the disc. The Pin model is a hybrid of the Shooter and the Datum (V in Fig.1) by utilizing the ramp from the Datum and the rubber band propulsion from the Shooter.

When I was told to watch a performance to write about, I had no idea where to go with watching something. I was stuck. But then I was thinking about it and thought, wait, what if I watch a performance art piece. It literally has performance in the name. This will work perfectly. I looked up some performance art beforehand, and to be honest, I wasn’t impressed with it and thought it was rather peculiar and a little inappropriate. With dabbling upon what I had looked up, I came across Marina Abramović. She caught my eye because of her way of talking. It is so unique and captivating that I couldn’t choose anyone else to watch and write about. If only there was a way to write this paper with the accent Marina has.

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.

Using the program Projectile Motion available at: http://phet.colorado.edu/sims/projectile-motion/projectile-motion_en.html the data for angle, weight, Air resistance, distance, and speed could be calculated. The first thing that had to be determined was how much the person (Suzan) was going to weigh, because it was determined impolite to ask an average 70kg was decided on for the weight of the projectile

Upon reviewing my own performance during this evaluation, I believe that it was effective in many areas. I allowed the mother to be present, which enabled the child to feel comfortable. Furthermore, we met at a familiar playground near Aidan’s home, which further added to the comfortable atmosphere. The playground was fairly quiet and empty. This helped me to spend the time needed with Aidan to get him speaking in a natural manner. However, in hindsight, I wish I had met with him in a more controlled, yet comfortable environment. The playground was both a blessing and a curse. Too many variables came in to play. Often, he would get bored in one section and want to move on to another. Thus, I would have to play catch-up with him and make sure

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

There are many aspects to the game of basketball and physics can be applied to all of them. Although to be good at basketball it is not necessary to play it from a physics point of view. Basketball players become good by developing muscle memory for the actions that must be performed in the game of basketball from years of practice. Nevertheless knowing some of the physics in the game of basketball can help a good player be a better player. In this paper I will cover the three most important aspects of the game, shooting, dribbling and passing.
