Center of mass

where potential energy is. Potential energy is the energy which results in position. Usually the most potential energy in a roller coaster is when it is about to start. The way that this type of energy is calculated and measured in P=MGH. M, being Mass, G being Gravity, which is always constant and is 9.81 N/kg and H being height of that point, and that is measure in…

M1 locate the bones, joints, movement types and muscles used during a range of sporting activities: Example 1 – Andy Murray tennis serve. The Andy Murray serve begins with him lining up at a 45 degree angle to the baseline. His legs are a little more than body width apart with the left foot about 30 degrees off the line. This stance means that he will be using a big turn of the whole body to assist in providing some of the power to his serve. His arms are extended out in front. His left hand…

Clifton Zhuo Dr. Greenberg World Religions 19 November, 2015 Experience in Catholicism On the nineteenth of November, I took part of the mass that was held in Loyola Marymount University. I have been in the Sacred Heart Chapel before. However, this would be my first time going into the St. Mary’s Chapel. When I decided to attend the mass at St. Mary’s Chapel, the first thing that came to my mind were the old memories of my childhood. I attended a catholic elementary school during my childhood…

Another Pound of Nothing For any wrestler, it´s a long and excruciating process, but well worth the pain to reach the pinnacle of his journey: to be a state champion. Before the wrestling season, a wrestler needs to be mentally and physically prepared. This journey is anything but easy, and sometimes to have the most success, wrestlers must cut weight. Cutting weight puts the wrestler at a lower weight, helping him control wrestling matches easier. The wrestler has to create physical goals…

result of an external force acting on it. The boat was designed according to Newton’s second law of motion. To create a greater acceleration rate, a carton of milk was used. The carton is very low in mass which allows for greater acceleration since the acceleration is inversely proportional to the mass of the…

Does society glamorize your weight and despise it at the same time? “You’re soooooo skinny!!!!” “UHHH, you’re just body goals!!” “You’re too bony.” These are only a couple of the lines that allude to my body image on a day to day basis. I know that I’m a short, petite young woman with an edge of sass. I fit society’s standards to an extent so, sometimes I don’t know how I should view myself when I look in the mirror. There are those infrequent moments when I think, “Should I complain about…

Galileo Galilei was born in Pisa, Italy in 1564 during the Renaissance.This was a rebirthing period in Europe started off in Italy for art, philosophy, and sciences. The Renaissance brought back many ideas from Ancient Greece and Rome introducing many scientists like Galileo. Attending the University of Pisa originally going to study medicine, he was taught the Aristotelian view on the world, later questioning it making way for many of his greatest discoveries. He was an outstanding astronomer,…

initial plan and how we believe it will help our egg survive the fall. The machine my partner and I are using has a strong, triangular foundation. This is made up out of popsicle sticks glued together for support. On top of the foundation, in the center, you will find the dixie cup, which will eventually carry the egg. Protecting the egg, we will attach the ten balloons with rubber bands and string, enclosing the egg completely for protection. Along with the balloons, popsicles framed upward…

falling precipitously. While the average pellet shot has a mass of no more than a few ounces and a duck weighs on the order of several pounds, the impact from the shot is enough to significantly redirect the trajectory of the duck. This occurs because while the pellet is very light, it is moving at an incredibly high speed relative to the duck. All moving massive objects possess this property of momentum, a quantity proportional to the mass of the object times its velocity. Momentum is what…

Sir Isaac Newton’s second law, acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed(needed to accelerate the object). Everyone unconsciously knows the second law. Everyone knows that heavier objects require more force to move the same distance as lighter objects. The second law gives us an exact relationship between force, mass, and acceleration. It can be expressed as a mathematician equation, the…
