When your dominant wrist is curled as far as it can go inward, start bringing your wrist back out and your arm back down to its starting position. Now you have to learn how to pass. To pass to another person, lower your dominant hand to the center of the shaft. Then bring the shaft of your stick back by twisting your shoulders toward your dominant side. Then keep your wrist next to your ear, in a quick and fast motion, flick the wrist of your top hand while pulling your top hand towards you.
This release of energy rotates the shaft and causes the throwing arm to move in a wide arc, launching the projectile from the attached basket. Trebuchets, on the other hand, do not rely of elasticity. They rely primarily on leverage to send projectiles soaring through the air. They use a “Class 1” lever, where a force applied on one end of the lever, creates motion in the other end to move the throwing arm. This force is provided by gravity when a huge counterweight at one end of the arm falls.
2.0 Body 2.1 Technically correct performance of the skill The purpose of the dig is to control the ball and pass it to the setter at the net. It is used as a defence move, especially after receiving a serve or a spike from the opposing team. 2 The dig is commonly used when the ball is below chest height, to bring the ball up to the team setter and stop it from touching the ground. 3 When preparing for the dig your knees should be bent, with feet shoulder width apart in an easy stride position, ready to move to the ball if necessary. Hands should be joined with thumbs parallel, elbows locked and arms should be parallel to thighs to create a flat platform to hit the ball with4.
They also show the proportional rate of the energy loss due to heat as the ball bounces. To maintain the bouncing of the ball the player must dribble it. Each time the player dribbles the ball, it exerts a force on the ball which allows the ball to maintain its energy level and to keep bouncing. The outside forces that are on the ball are gravity and the player's hand. Gravity is the pull of the earth toward an object.
The arms are positioned together comfortably in front of the chest with the hand and ball in the glove. Then the arms are brought down and back simultaneously to the frontal plane in line with the shoulders. The throwing arm is on the frontal plane is back in an L shape position facing the target; this is called the power position. The glove arms elbow and upper arm is on the frontal plane but the forearm is on the transverse plane with the glove pointing to the target. The shoulder girdle has an anterior tilt when arms reach their position.
2 Dribbling Drills 1) Figure 8 Dribble Stand in the triple threat position (feet roughly shoulder width apart, one foot ahead of the other, knees bent). Using your right hand, dribble the ball around your right foot from front to back. Once the ball reaches between your legs, switch to your left hand and dribble the ball around your left foot. Each time the ball comes back to the center, switch hands and dribble around the other foot, keeping the ball just a few inches off the ground with the dribble. 2) 2-Ball Dribble Drills Two ball drills are some of the best possible drills for improving your ball handling skills.
Speed is a key factor in the game. The faster you are the better. Not only is running speed important, but the speed at which you pass or move the ball can be the key. The faster this is performed, the harder the time the opponent will have predicting and reacting to the move. A fourth and vital skill is communication.
The ballista is possibly the first large, siege-like catapult. It comprised two wooden arms, tightly wound ropes and a cord to assist in the hurling of deadly projectiles, such as spears, at an enemy. The catapult gets complex over the year, because more materials are put together to make the catapult more advance. The catapult answered humanity’s need to propel a projectile successfully over a great distance with some “mechanical” help. The catapult varies, for example the trebuchet is a catapult meant for launching heavy items to knock down something.
For the punch to become more powerful we would have to accelerate the mass using energy. The energy for the punch comes within in the whole body not just the arm that is striking. By increasing muscle mass the force of the punch will increase through energy transferred thought out the body. Energy transfers from one muscle group to another until it is released by the fist striking the opponent. The major muscles that are involved when preforming a right cross punch are include deltoids which power the extensor muscles of the
The golf club is a major factor in power creation, especially the shaft’s flexibility. The illustrations are full-body models of a golf swing and the specific path of the shaft throughout the swing. A simple double-pendulum of the golf swing will also display the wrist-cock angle. Rod White wrote in the American Journal of Physics “It is…[concluded] that the wrist-cock angle is the most significant efficiency-determining parameter under the golfer’s control and that improvements in golf technology have had a significant impact on driving distance” (White).
