Gavagan CJ, Sayers MGL. A biomechanical analysis of the roundhouse kicking technique of expert practitioners: A comparison between the martial arts disciplines of Muay Thai, Karate, and Taekwondo. PLOS ONE. http://journals.plos.org/plosone/article?id=10.1371%2Fjournal.pone.0182645. Published August 25, 2017. Accessed February 5, 2018. Purpose: The purpose of this study was first, to determine whether there were differences in the roundhouse kicking leg kinematics performed by highly skilled…

The seatbelts purpose was to keep the egg secure during the impact. In order to do this, Newton’s first law had to be taken into consideration, objects at rest, stay at rest; object in motion, stay in motion… unless acted upon by an unbalanced force. Because the egg would have kept going until acted on by an unbalanced force, we suspended it with rubber bands so that the unbalanced force to stop it would not be the ground but it would be the pressure applied by the rubber band. This also Apply…

Sullivan Jackson Kachigan Physics 16 February, 2018 SAHC: SJ How Mass Effects Luge Luge is an unusual sport where the rider or riders on a sled-like device are barreling down an ice track at speeds up to 97 mph. Because of these tremendous speeds, one may think that the rider(s) must be light and nimble so they could glide through the course with ease. However, this is the complete opposite of reality and in the physics world, it makes complete sense. As you may have guessed, the…

Kinetic Energy and Potential Energy Math Exploration 2/14/2018 Part 1: Finding Kinetic and Potential Energy Directions: For each situation, you need to determine if the object has KE or GPE or both. Then find their values. Be sure to include the correct units. 1. A 2-kg bowling ball sits on top of a building that is 40 meters tall. Circle one: KE / GPE / both Show your work for finding the values of each type of energy the object has: The ball is not moving and is at a height above…

Sir Isaac Newton was one of the greatest minds of the 17th century Scientific Revolution. He helped develop the principles of modern physics and also a new type of math called calculus. His book Philosophiae Naturalis Principia Mathematica has been called the single most influential book on physics (“Sir Isaac Newton”, 2014). Despite all this, he remained a humble man who once said, “If I have seen further than others, it is by standing upon the shoulders of giants (“Isaac Newton”, n.d.)”.…

Running Head: SPIKING MOVEMENT ANALYSIS 1 Movement Analysis of Spiking a Volleyball Jordan Bevins Indiana University East SPIKING MOVEMENT ANALYSIS 2 Abstract This paper is set to analyze the phases spiking a volleyball. Movements can generally be separated into three to five main phases. During each phase different muscles, joints, and bones come into play. The phases and all of the parts that combine to constitute a phase can be further broken…

The purpose of this lab was to find the acceleration of a toy car and create graphs to display this acceleration. These graphs will then be compared to graphs of what is expected for perfect constant acceleration. In order to find the acceleration of the toy car, a strip of ticker tape was attached to one of those toy cars that you pull back and move once your hand releases the car. After attaching the ticker tape and feeding the tape through the spark timer, the timer was turned and the car…

Literature demonstrates that pitch types (fastball, curveball, change-up, slider) generally have similar kinematics with only minor differences in forearm and wrist action, and even less so in the elbow and shoulder(36-40). Fleisig et al demonstrated in a kinematic study involving 21 collegiate baseball pitchers that the change-up pitch is the least stressful, while the curveball and fastball have similar elbow and shoulder kinetics, with the curveball exhibiting increased forearm supination and…

Albert Einstein and Isaac Newton, both intelligent, driven, revolutionary scientists who changed the way we look at the world. Their advancements science can still be felt in our everyday lives. Both Newton and Einstein made equal contributions to modern physics and mathematics, with Einstein building upon Newton’s theories, impacting the world today. Isaac Newton, born December 25th 1642 (January 4th 1643 depending on the calendar) in Woolsthorpe in Lincolnshire England. He was the only son…

Isaac Newton Sir, Isaac Newton Is a large figure in the history of science mostly for his laws of science but what about his contribution to the enlightenment. Isaac Newton developed and contributed in huge ways that play a very big factor in the Enlightenment and in the way we comprehend the world today. Sir Isaac Is responsible for the creation of calculus which is a big brand of mathematics, this is still largely used in the world today. Also his most famous contributions were his…
