Projectile: an object thrown into the space either horizontally or at acute angle under the action of gravity is called a projectile. In the field of games and sport there are many examples of projectiles such as putting the shot, throwing a hammer, discus, and javelin in athletics. Propelling Force: The propelling force produces certain effects depending upon its point and direction of application. As the projecting force is moved further from the centre of gravity, rotator motion of the object increases at the expense of linear motion.

Forward spin results when the force is above the centre of gravity. When the force is off centre to the left, clockwise spin results and when it is off centre to right, counter clockwise spin occurs.

Force of Gravity: As soon as contact is broken with a projected object, the force of gravity begins to diminish the upward velocity of the object. The factors that determine how soon gravity will cause the object to descend are — a Weight mass of the object b amount of force driving it upward C the effect of air resistance on the object. The more surface area an object presents in the direction ofmovement, the greater will be the effect of air resistance. The three laws of motion formulated by Newton are described below 1.

Law of inertia: According to this law a body at rest will remain at rest and a body in motion will remain in motion at the same speed and in the same direction unless acted upon by an external force.

There are great examples of this law in sports such as starting in rowing, starting in sprinting, starting in throwing the hammer. Basically if an object is in motion, it remains in motion unless something or some external force stops it.

The external force may be gravitational force, the surface of playing field or a defensive player etc. For Ex: Starting in sprinting, starting in rowing, starting in hammer throw.

Law of acceleration: According to this law, A change in motion is directly proportional to the force producing it and inversely proportional to its mass. If two unequal forces are applied to objects of equal mass, the object that has greater force applied will move faster. Conversely, if two equal forces are applied to objects of different masses, the lighter mass will travel at a faster speed.

In swimming, a swimmer pushes the water backwards action. The water pushes the swimmer forward reaction with the same force. It is the force that is the opposite of weight. The weight of an object controls how strong the push has to be.

A shot of 16 pounds requires more force push than a javelin. It makes hard for an object to move. It is harder to walk through the water than through the air. It is because water causes more drag than air. Thrust : Thrust is a force that is the opposite of drag. Thrust is the push that moves some objects forward. It is very important in sports. When both the surfaces are smooth, the force of friction reduces to almost zero.

Three types of friction are i Static Friction The opposing force that comes into plc when one body tends to move over the another surface but the actual motion has not yet red ii Limiting Friction Limiting friction is the maximum of thing force that comes into play when one body is just on the verge of moving over the surface of another body. There are following types of planes: a Sagittal or Medial plane: The sagittal plane is a vertical plane passing from the rear to the fronty, dividing the body into left and right halves.

It is also known as anteroposterior plane. Most of the sports and exercise movements that are two dimensional, such as running, long jumping and somersault take place in this plane. It is also known as coronal plane. Frontal plane cuts the body into front and back. Mvements along the frontal plane can include cartwheel and star jumps.

In fact, it divides the body into upper and lower sections. This plane lies horizontally that why it is also called horizontal plane.

Movements along this plane can include an ice-skating spin or rotation to play a tennis shot. Movements at the joints of human muscoskeletal system are mainly rotational and take place about a line perpendicular to the plane in which they occur. This line is known as axis of rotation. There are following types of axes of rotation: a Sagittal axis: The sagittal axis passes horizontally from posterior to anterior.

It is formed by the intersection of the sagittal and transverse plane. Sagittal axis passes from front to back. It is formed by the intersection of frontal and horizontal plane. Frontal axis passes from side to side. It passes straight through the top of the head down between feet.

It is formed by the intersection of sagittal and frontal plane. It is also known as longitudinal axis.

It is the longest axis. There are various types of movement in body parts which can be divided in four types i. Angular movement : Angular movement occurs between long bones. By angular movement the angle between the two bones increased or decreased. Circumduction : Circumduction is that movement which takes place between the head of a bone and its articular cavity. This kind of motion is best seen in the shoulder and hip joints. Moving a part around an axis is called rotation.

Twisting the head from side to side. The major muscles involved in running are described below: Glutes: these muscles stabilize your hips and legs. These muscles work with hamstring muscles and help in hip flexors. Quads: Quads propel you forward and help straighten out the leg in front so that it can make a good contact with the surface of ground. Calves: these muscles give you spring in your step and at the same time these muscles act as shock absorbers.

Hamstrings: As you move forward, the action switches to your hamstrings, the muscles at the back of your thigh muscles. These muscles helps you in pulling the leg back behind and give you strength to propel your body forward.

Core muscles: Strong abs and back are really important because they keep yours posture upright and overall form good. These muscles play a significant role in running. Biceps: biceps also play a vital role in running. Biceps maintain a bent arm and help in swinging your arms back and forth while running.

The leg, feet and gluteus muscle groups are used in jumping. Specific muscles which are involved in jumping are gluteus maximus, hamstrings, quadriceps and soleus. In fact, jumping occurs in three stages. The first stage is the preparatory stage where ankle muscles calf muscles and soleus tense to prepare launching.

The second phase is the launch phase, where hip extensors, the hamstrings, and gluteus maximus combine and the knee extensors extend the knees to allow the body to launch into the air. In the last stage is the landing phase where all the muscles embrace impact and allow the body to return to a resting position. The major muscles are pectorials, major, latissimus dorsi, anterior deltoid and teres major are involved in throwing.

These muscles are comparatively responsible for velocity during the throw. The pectorials major is the large muscle in the chest and latissimus dorsi are the large muscles on each side of the back. Deltoid, biceps, triceps are also involved in throwing a javelin in athletics.

Kinesiology and physical education study the role exercise, physical movement and sports play in the development of human health and happiness. They apply sciences like biomechanics, anatomy, physiology and psychology to better understand how the human body responds to physical activity. To succeed in kinesiology and physical education students should be interested in the benefits and processes related to fitness and physical activity. Students will need to develop strong critical thinking skills in order to think critically about the role of activity as a means to promote health and well-being. The study of kinesiology and physical education may be used as the basis for a variety of careers which include athletic trainers, choreographer, coach, athletic director, corrective therapist, personal trainer, physical therapist, recreational specialist, or teacher to name a few.

kinesiology and biomechanics, as well as exposes students to fundamental movement, particularly those pertaining to exercise, sport, and physical activity.

Просто мне приходится быть крайне осторожным. В тридцати футах от них, скрытый за стеклом односторонней видимости Грег Хейл стоял у терминала Сьюзан. Черный экран.

Стратмор сощурил. - А ты как думаешь. И уже мгновение спустя ее осенило.

Бринкерхофф со смущенным видом повернулся к Мидж: - Это Джабба. Он хочет поговорить с .

- Эдди места себе не находит. - В Коннектикут. - Я же сказал.

И словно по волшебству все встало на свое место. Это произвело на дешифровщиков впечатление, но тем не менее Беккер продолжал переводить знаки вразнобой, а не в той последовательности, в какой они были расположены в тексте. - Это для вашей же безопасности, - объяснил Морант.

Судя по той увлеченности, с которой молодой профессор говорил о преподавательской работе, из университета он не уйдет. Сьюзан решила не заводить деловых разговоров, чтобы не портить настроение ни ему ни. Она снова почувствовала себя школьницей. Это чувство было очень приятно, ничто не должно было его омрачить. И его ничто не омрачало. Их отношения развивались медленно и романтично: встречи украдкой, если позволяли дела, долгие прогулки по университетскому городку, чашечка капуччино у Мерлутти поздно вечером, иногда лекции и концерты.

Единственный исполнитель. Сьюзан пронзила ужасная мысль. Этой своей мнимой перепиской Танкадо мог убедить Стратмора в чем угодно. Она вспомнила свою первую реакцию на рассказ Стратмора об алгоритме, не поддающемся взлому. Сьюзан была убеждена, что это невозможно. Угрожающий потенциал всей этой ситуации подавил. Какие вообще у них есть доказательства, что Танкадо действительно создал Цифровую крепость.

- Из всех различий между ураном и плутонием наверняка есть такое, что выражается простым числом. Это наша главная цель. Простое число.

Вот. Все прочитали: - Разница в весе незначительна… разделяются вследствие газовой диффузии… 10,032498X10134 в сравнении с 1939484X1023. - Ну вот, наконец-то! - вскрикнул Джабба.

Сквош, - чуть не застонал Беккер. Сьюзан сделала вид, что не поняла. - Это похоже на цуккини, - пояснил он, - только корт поменьше.
