What is summation of force

To do this athletes use in the execution of a skill as many body parts or segments as they possibly can. A sum or aggregate. Force is the product of the mass weight and acceleration of an object or person.

The act or process of adding. A force has both magnitude and direction making it a vector quantity. In physics a force is any interaction that when unopposed will change the motion of an object a force can cause an object with mass to change its velocity which includes to begin moving from a state of rest i e to accelerate force can also be described intuitively as a push or a pull.

To further understand this relationship, we have to understand what mass is as mass and weight are often used interchangeably but they are not the same thing. Mass is the amount of matter that an object has. In the physics world , mass is described as the amount of force needed to cause an object to accelerate.

Weight, on the other hand, is a measure of the force of gravity on the object. When you weight yourself, your weight is actually the measurement of force of gravity pulling down multiplied by your mass. How, then does all of this apply and affect performance? Your body has the same mass running down the track or on the field or in space. However, when looking at force and acceleration, it gets a little more complicated since they both have magnitude and direction.

And force can be a single force or multiple forces. When sprinting down the track for example, different body parts produce different forces to produce the desired effect — moving the body in a given direction as fast as possible. The multiple forces acting on the body and the combination of all forces acting on the body together is the theory of summation of forces.

In the human body, movement is achieved by a complex and highly coordinated mechanical interaction between bones, muscles, ligaments and joints within the musculoskeletal system under the control of the nervous system.

Muscles generate tensile forces and apply torque at joints in order to provide static and dynamic stability of the body under gravitational forces and other loads while regularly performing precise limb control.

In other words, force is created by these joints so that specific movement occurs. Remember the inverse relationship between mass and acceleration — as mass goes up, acceleration goes down. In theory, force summation occurs when all body parts act simultaneously In practice, the strongest and lowest body parts around the centre of gravity e. What is summation of force? What is the study of biomechanics? Biomechanics is the study of the structure, function and motion of the mechanical aspects of biological systems, at any level from whole organisms to organs, cells and cell organelles, using the methods of mechanics.

How is force summation used in volleyball? Summation of force is defined as 'to obtain maximum force with any movement where many muscles are used' P. Fordham, Force summation requires all body parts to move in sequence. In order for maximum force to be applied in a volleyball spike, the player needs a stable base from which to start the movement. What causes impulse physics? The equation is known as the impulse-momentum change equation.

The law can be expressed this way: In a collision, an object experiences a force for a specific amount of time that results in a change in momentum.
