This is measured by the equation ‘torque = inertia x angular acceleration (t=la)’ and will play a huge part in ball placement. Abstract This paper presents a description of a simple ballistic pendulum used for assessing ball speed and forces in volleyball.
Torque refers to the movement of force being the magnitude of force which causes the rotation of an object (Blazevich, 2012, p.63).
Gravity of the ball increases the force needed for energy transfer which translates into more work for the player. In volleyball the aim of the game is to strike a ball into play that your opponent cannot return or finds it difficult to return. A friction force that makes this possible is the friction of the air on the ball, for example when a player hits a ball with topspin into play, the friction of the air on the ball makes it spin faster than it otherwise would. Acceleration of your arm and torso increase the velocity of the ball. High shoulder forces and torque are generated in the volleyball spike (Escamilla & Andrews, 2009, p.580). Too much force and you overshoot, too little and you undershoot. By doing this a greater distance between the axis of rotation (shoulder) and the point of contact (hand) is … All of the above are forces used in volleyball. When someone passes a volleyball the ball moves in the direction that the passer is aiming, which is to the setters hands. Whenever … Twelve volleyball … In other words, it is important to know how gravity works and the effect it will … A seven‐meter long pendulum with a wooden block of mass 10 kg was constructed and then used in conjunction with a specially designed timer with a precision of 10‐3s to measure ball speed, pendulum speed and forces exerted to the ball and to the hand.
In volleyball, the force is the player and the object is the ball. High shoulder forces and torque are generated in the volleyball spike (Escamilla & Andrews, 2009, p.580). To maximise the volleyball spike it is essential to create a longer lever. (Blazevich, 2012). Someone has to exert enough force to keep the ball in the air long enough to be set by another teammate before gravity pulls it down again. When making the connection with the volleyball, the moment of force (torque) is important to take into consideration. Another important biomechanical principle which relates to the ball … Spiking is the most effective because it works together with gravity to produce a powerful downward force towards the opponent much like serving if done so appropriately.
