# The Importance Of Motion In Soccer

Better Essays
Soccer is a sport that involves running, jumping, kicking, sliding defending etc. A sport that would not be possible if we were unable to move, but what exactly causes our body to move? What are the factors that help produce movement? Many might think we move because of muscle contractions but there is more to it than the shortening and lengthening of a muscle. There are forces and laws that influence every movement produced by the body. Every movement has different forces, and laws that apply to the movement. When striking a soccer ball important mechanical principles and concepts such as stability, motion, force, and Newton’s law affects the outcome of the strike. Stability is what many people consider balance. So in other words stability …show more content…
Newton’s First Law, the law of inertia, states that an object in motion will remain in motion unless it is acted upon by an outside force such as gravity or friction. Not surprisingly, a not in motion will remain not in motion unless an outside force acts on the object. Additionally, in order for movement to stop the outside force must be strong enough to overcome the inertia from the object. In order for an object to move the outside force must be enough to overcome the resistance offered by the object. Newton’s Second Law, the law of acceleration states that, “velocity is directly proportional to the force producing it and inversely proportional to the object’s mass” (Fisette 194). Newton’s Third Law, the law of action and reaction, states, “that for every action there is an equal and opposite reaction” (Fisette …show more content…
During the approach the player has 3 or 4 steps to pick up velocity. During this phase the player is in linear motion toward the soccer ball. The approach phase ends when the player plant their non- kicking foot next to the ball. Next is the contact phase. During the contact phase the kicker bends his knee and then contracts the quad muscles causing the knee to extend and create force. The force picked up while approaching the ball also gets transferred. To ensure maximal force the kicker should have a fully stretched planted leg and lean over towards the planted leg. Furthermore, it is important for the player not to lean to much since the center of gravity is in movement and the kicker has a small bass which means lower balance. By planting one leg and leaning over a bit it allows the kicking leg from deceleration, “due to the angle of the hip and pelvis to allow the leg to swing through” (Frezno). The last phase in kicking a ball is the follow-through. During this phase the players transfers his/her weight towards the kicking leg. The transfer in mass allows the player to put more force behind the ball and allows him to land on the kicking

If the particle has initial position x1, initial velocity v1, final position x2 and final velocity v2, we have ∫_(x_1)^(x_2)▒〖F_t dx〗=∫_(v_1)^(v_2)▒mvdv ∫_(x_1)^(x_2)▒〖F_t dx〗=(mv_2^2)/2-(mv_1^2)/2 The first term in the above equation is the work done by a force and the second and the third terms are kinetic energies of a particle. Since the work due to a force is scalar quantity, kinetic energy of a particle is also a scalar quantity. We write above equation as U_(1→2)=T_2-T_1 T_1+U_(1→2)=T_2 Eq. 2.10 Eq. 2.10 is the mathematical representation of the principle of work and energy for a particle.…

It does that because gravity slows it down until it hits its peak. Then the ball comes down while gravity accelerates the football until the person catches it or it hits the ground. When someone kicks the football, they control three things. Those three things are the angle, the rotation of the ball, and the speed or velocity when it leaves their foot. The velocity and the angle of the kick determine how long the hang-time will be, how high it will go, and how far it will go.…

What is inversion therapy? Inversion therapy is method where you are hanging inverted to relieve back pain and stretch the spine. This therapy works by shifting the body’s gravity, easing the pressure off the back and providing the traction for the spine. This upside down therapy is best for those people who are suffering from sciatica, poor circulation, scoliosis and chronic lower back pain. It is a technique of being upside down while hanging by the ankle or feet in order to have the therapeutic benefits.…

To strike with the ball of your foot, you need to pull back your toes, exposing the ball of your foot. Performing the front snap with the ball of your foot is more advanced and takes additional practice. Through continued practice, however, the ability to instantly pull back your toes will become quite natural. The reason it is so important to pull back your toes (Even if you are wearing shoes), is that if you leave them in their naturally extended position, they can easily be broken when target impact is made. The basic front snap is an ideal close-contact fighting weapon.…

Your focus should not be on fatigue, it should be on muscle tension. Thus, alternating both legs to give the other a rest and completing the movement as explosively as you can is recommended. 4. Eliminate deceleration. Jump-out of the one-leg squat and land on both feet, then switch and repeat again.…

We also know that momentum can be further described as p=M*(dvCM/dt). By inspection we recognize that dvCM/dt is the definition of acceleration of an objects center of mass. By these derivations, we come to understand Newton’s second law. Newton’s Second Law of Motion states that Fnet,ext=MaCM meaning that the net external force acting on some object will cause its mass to accelerate. The net force here is inclusive of all external forces (Moore).…

Lab Report: Uniform Motion Table of Contents Background Information 1 Research Question 1 Hypothesis 1 Variables 1 Materials 2 Procedure 3 Background Information Motion is the change of position of an object with respect to time. The physical quantities velocity, acceleration, displacement, time and speed are used in the study of motion. If an object does not change position with respect to time, it is considered as stationary. Note that if an object is motionless, it does not necessarily mean that there is no force acting on it. Motion can also be studied by using momentum (f=((mv-mu))/t ) as a quantity.…

Static friction is given by Fs< usn where N is the normal force between the object and its support surface and us is the coefficient of static friction. There-fore, the coefficient of static friction is given by Us= fs, max/ N Where F s, max is the maxixmum force of static friction. Once the external force overcomes static friction, the object moves. Its motion is opposed by kinetic friction. The force of kinetic friction is given by f k = ukN where u k is the coefficient of kinetic friction.…

The equation for acceleration is: a=∆v/∆t in which the variable a represents acceleration, ∆v represents the change in velocity, and ∆t represents the time interval. In addition, gravity is the force that attracts a body towards any physical body that has mass. Galileo Galilei discovered that the distance a standard accelerating object travels is proportional to the square of the…
