Without the movement of the lower body, a shot would end up anywhere but the back of the net. The lower body helps a player produce a straight shot so the ball winds up leaving the stick in the direction that the shooter intended.

“Maybe our mistakes are what makes our fate.” -Carrie Bradshaw. Throughout reading The Crucible, flaws within each character, and the actions they made based upon those inner flaws, eventually lead to their “downfall”. John Proctor was a highly respected man by the community of Salem, as well as by himself.

Tennis serve is the shot that starts off the point. It is normally instigated by pitching the ball into the air and thumping it into the diagonally opposite service box exclusive of touching the net. This act is attained underhand or overhead. It is the only attempt where a player takes his time to position up, instead of reacting to an opponent’s shot. In doing this, high percentages of the efforts are normally exerted at the upper extremity of the body, while the rest at the lower extremity of the body. the serves comes in five main types of which includes; cannonball or flat serve, topspin-slice serve, slice serve, American twist serve and the topspin serve. The paper will focus on the some of the types of the serves and the ways in which the upper extremity are involved in the game. With this, it will look at the movements that occur at each of the upper extremity together with the muscles that are in use at the joints.

The physics involved in soccer includes friction, torque, center of gravity, Magnus Effect and Newton’s three laws of motion. The physics of soccer comes from three main parts of physics which is velocity, acceleration, and displacement. Velocity is shown in soccer with the speed and direction of the soccer ball when it is hit or kicked. Acceleration is shown in soccer when the ball changes velocity when it is hit or kicked. Displacement is the change in position of the soccer ball.

The placement of the non kicking foot determines the direction of the kick. The support leg also acts as a stabilizer by flexing at the knee once the foot makes contact with the ground. (Lees, Asai, Andersen, Nunome & Sterzing, 2010) Pictured below in Figures 1 and 2 are two different athletes with very diverse abilities. You can see both the direction of the planted foot and the flexion of the knee in both players.

As the tennis server prepares to swing their racket in the serve, they bend their knees, which stores elastic potential energy in their legs. This elastic potential energy is also referred to as strain energy. As the legs are bent the muscles and tendons are stretched in a way that stores this strain energy(biochmechanics). The greater the bend and stretching in the legs, the greater the power generated as the legs are extended(biomechanics). As the tennis player extends their legs this elastic potential energy is converted to kinetic energy and a ground reaction force is generated. This ground reaction force can also be called normal force. As the player extends their legs the tennis court ground in contact with their feet is compressed

From an early age I have frequently questioned who I am. I, obviously, am the daughter of Chris Dudley and Donna Terrill. I am a quiet girl from South Carolina with brown hair and glasses. These things make me who I am, but at the same time do not. Over the years I have come to realize that who I am really isn’t about who I am right now or who I am physically, but about who I want to be.

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.

In the tennis serve Newton’s third law of motion is applied as the player performs a leg drive to the court to generate an equal and opposite reaction (Ackland, Elliott & Bloomfield, 2009, pp 314).

Playing tennis involves more muscles than simply your arm and wrists. It involves a series of complex movements that start with your feet and ends up swinging a tennis racket. It requires a honed and well-trained muscular system to perform with the required power and speed needed. The muscular system is one of the most important systems involved in the sport of tennis. The muscular system is the tissue of fibres around your bones. This is a main part of tennis because specifically these muscles will put force on the bones and pull them. This will result in the tennis player getting more power behind there hit and also helps the play with moving around the court in a quicker pace.

Punting a football can be intensively and precisely explained through the study of structural kinesiology. Punting is a skill that is often referred to as kicking. It is performed by releasing the ball from the hands and kicking the ball before it strikes the ground. Punting is an action that takes place in the sagittal plane around the frontal axis. The joints involved are the: atlantooccipital (cervical), intervertebral (lumbar), scapulothroracic (shoulder girdle) glenohumeral (shoulder) humeroulnar (elbow) radiocarpal (wrist) metacarpophalangeal and interphalangeal (fingers) acetabularfemoral (hip), tibiofemoral (knee), talocrural (ankle) and the metatarsophalangeal and interphalangeal (great and

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.

Courage and bravery leap to mind first when we think of heroism. It's difficult to achieve anything truly heroic unless you're up against daunting odds. As Nelson Mandela put it, "Courage is not the absence of fear, but the triumph over it."

In order for maximum force to be generated, a tennis player needs a good stable base from where they can begin the movement. The tennis serve begins with flexion of the knee joint caused by the hamstrings. Then comes extension of the knees as well as hip flexion to start the movement - both of these movements are initiated by the quadriceps. The Erector Spinae muscle causes trunk extension to allow the abdominals to fully flex the trunk and generate the force that is then transferred to the upper body. The deltoids and pectorals major are used to flex the shoulder. These muscles are used to accelerate the whole arm while also stabilising the shoulder. Once the arm has begun to accelerate towards the ball, the tricep brachii is then used to
