CHAPTER 2 LITERATURE REVIEW 2.1 Introduction Based on the case study that is two-dimension single-camera based motion analysis as team sports strategic tool, the literature review divided into four main topics. First topics are about the human body motion analysis. In this topics will be explained deeply on the human motion analysis which referring the biomechanics of human body. Biomechanics of human body divided into three sub-topics, which are kinetics for analysing human motion, kinematics for analysing human motion and dynamics for analysing human motion. Second main topic in this chapter will discovered the sport of netball. It will cover the position of each player and the strategies and techniques of netball. This is important …show more content…
These include compression, tension, shear, bending, and torsion. Generally, some combination of these loading modes is present. The distribution of force within a body structure is known as mechanical stress. The nature and magnitude of stress determine the likelihood of injury to biological tissues. Other factors that affect the behaviour of two bodies in contact when a collision is involved are momentum and elasticity. Linear momentum is the product of an object’s mass and its velocity. The total momentum present in a given system remains constant barring the action of external forces. Changes in momentum result from impulses, external forces acting over a time interval. The elasticity of an impact governs the amount of velocity present in the system following the impact. The relative elasticity of two affecting body is represented by the coefficient of restitutions. Mechanical work is the product of force and the distance through which the force acts. Mechanical power is the mechanical work done over a time interval. Mechanical energy has two major forms; kinetics and potential. When gravity is the only acting external force the sum of the kinetics and potential energies possessed by a given body remain constant. Changes in a body’s energy are equal to the mechanical work done by external
An elastic collision between two objects is one in which total kinetic energy (as well as total momentum) is the same before and after the collision.
The term biomechanics means the study of the structure and function of biological systems using the methods of mechanics. Biomechanics studies the process of kinematics and develops artificial limbs and footwear specifically to aid the body in performance. The study of biomechanics also includes the stress testing on crash dummies in car accidents and any sport where stress is placed on the body in order to produce performance. The type of stress specifically is the joint stimulation and bone modeling stress.
Appendix: page 13. Rubric: page 14. Introduction: Grade 12 Physical Science learners at Penryn College were tasked with carrying out an experiment to investigate the effect of collisions on momentum. Different mass pieces (500g; 1kg and 1.5kg) were dropped on a moving trolley and the learners observed the velocity of the trolley before the mass pieces were dropped on the trolley and the velocity after the mass pieces were dropped.
The evolution of animation is a topic I passionately connect to. I have enjoyed animation ever since I was a child, and it provides a comforting feeling to me. Stop-motion animation uses methods that are tedious and time-consuming, while computer animation is less technical and costly. Another way of distinguishing the two forms of animation is physical vs. virtual; traditional animation uses physical materials and activities, while computer animation uses virtual elements in a digital space. Although computer animation grosses more at the box office; stop-motion animation is a medium that often goes underappreciated, requires hard work and dedication, and is immensely original.
Each body can be considered an elastic half-space, i.e., the area of contact is much smaller than the characteristic radius of the body.
When a mechanical structure is subjected to some force, it undergoes deformation .stress describes the intensity of force on a structure as force per unit area
Physical mobility is something we rely on from day to day to be able to live independently and at ones discretion. However, many older adults going through the aging process may encounter a decline in their physical mobility. This decline in mobility can range from moderate to profound, but no matter what will have a significant influence on the elder adult’s lifestyle. A decrease in physical mobility can be caused by many different life aspects such as inadequate hospital care, a lack of physical activity, and vitamin D intake. A decline in physical mobility with older age is usually inevitable. However, a substantial decrease in physical mobility can be prevented by simple lifestyle changes. Frequent exercise, proper nursing/hospital care
In Chapter 14 (Kinetics of a Particle: Work and Energy) and Chapter 18 (Planar Kinetics of a Rigid Body: Work and Energy), both apply a same concept. It is concept of work and energy to solve the problem. Chapter 14 use the concepts of work and energy to analyze motion of a particle, while Chapter 18 apply work and energy methods to solve planar motion problems. In both chapter, problems that involve force, velocity, and displacement can be solve by using the resulting equation.
The way that each individual interprets, retrieves, and responds to the information in the world that surrounds you is known as perception. It is a personal way of creating opinions about others and ourselves in everyday life and being able to recognize it under various conditions. Each person’s perceptions are used as a kind of filter that every piece of information has to pass through before it determines the effect that it has or will have on the person from the stimulus. It is convincing to believe that we create multiple perceptions about different situations and objects each day. Perceptions reflect our opinions in many ways. The quality of a person’s perceptions is very important and can affect the response that is given through different situations. Perception is often deceived as reality. “Through perception, people process information inputs into responses involving feelings and action.” (Schermerhorn, et al.; p. 3). Perception can be influenced by a person’s personality, values, or experiences which, in turn, can play little role in reality. People make sense of the world that they perceive because the visual system makes practical explanations of the information that the eyes pick up.
Forces play two fundamental roles: to cause an object to move or to change shape (Lawler, 2018). Although there are a variety of forces to study- from inertial forces to gravitational ones- they all utilize at least one of those functions. Impact forces are no exception. Impact forces are those that involve a collision between two objects (Lawler, 2018). Impulse is a concept in physics that is governed by these ever-present forces. Impulse is the product of force and time that equals to the amount of change that the product of mass and velocity (momentum) undergo (Lawler, 2018). Human movement incorporates force in two ways: by maintaining static equilibrium- that is resisting the force of weight- and by generating acceleration, which is essentially a change in momentum (Schilling et al., 2008). Pressure,
Projectile motion is key component in everyday life. Whether it’s a football player kicking the ball to score a winning field goal or a frustrated student crumpling up a piece of paper and tossing it into the trash can, projectile motion is all arounds us. The idea of projectile motion was taught to us by varying physicists like Aristotle and Galileo. Using Aristotle's original notion that shot objects stay along a straight path until its impetus is lost, the famous physicist Galileo discovered that projectiles instead follow a curved path. Galileo also found that projectile motion is understood by thinking of the horizontal axis and vertical axis separately.(1) Galileo and Aristotle’s ideas of projectile motion could be represented
Stress is in all probability the most imperative word in the subject matter of strength of materials. Stress is defined as force per unit area. It has the same units as pressure, and in fact pressure is one special variety of stress. However, stress is a much more complex quantity than pressure because it varies both with direction and with the surface it acts on. The simple stress are: compression (stress that acts to shorten an object), tension (stress that acts to lengthen an object), and shear (stress that acts parallel to a surface). Shear can cause one object to slide over another. It also tends to deform originally rectangular objects into parallelograms. The most general definition is that shear acts to change the angles in an object.

As we discussed in class, collision can either occur in one-dimension or two-dimensions. Collision is based off the concept of momentum. Momentum is conserved in any type of collision. Momentum is found by taking an object's mass and multiplying it by its velocity. There are three types of collisions. There is inelastic, perfectly inelastic, and elastic. Inelastic occurs when when the collision does not conserve kinetic energy. An example might be dropping a ball from a certain height and because of inelastic collisions, it won't get as high as the initial spot at which it was dropped. It is the same thing with a perfectly inelastic collision, except the objects will stick together and the the maximum amount of kinetic energy is lost. In an elastic collision, the kinetic energy is conserved. An good example to see is watching pool, when the balls collide, it is elastic because they bounce off of each
