1.0 Abstract The purpose of this experiment is to analyze the efficiency and technique of the students over arm volleyball serve after the use of biomechanical principles has been applied. In order to complete the experiment the student performed a pre and post test which was evaluated by the program Dartfish and a serving indicator test to assess the changes and improvements of the students technique and performance of the over arm serve. It was found that by applying the three biomechanical principles

explosives to launch a projectile or a group of projectiles towards a target. Usually‚ the long arms is pulled back by a ropes or set of ropes‚ then letting them go‚ causing the long arm to swing forward. However‚ this is not the only way a catapult is used. There are 5 different types of catapults: the trebuchet‚ the Ballista‚ the Mangonel‚ the Springald‚ and the Onager. The trebuchet uses a counterweight attached to a long arm with a pivot in the middle to launch a projectile in a sling. A Ballista

Discussion The results did not give enough accurate data‚ due to the ability of the catapult and the weights used‚ the point at which the projectile stopped being efficient was not evident. If the experiment had been undertaken in more controlled and technology used more efficiently‚ like a robotic catapult‚ than the effect of weight on the motion of a projectile would have become more apparent. Furthermore‚ the reliability of the experiment would be drastically increased due to the use of more accurate

charge. The rush of fire that is about two-thousand degrees Celsius inflames the explosive which incinerates at an excessively high acceleration to create a huge amount of gas. This high force gas increases the projectiles speed into the barrel and out of the muzzle (Heard‚ 2008). Once the projectile exits the muzzle‚ gas force‚ discharged‚ matches about thirty percent of the initial force. When backfire occurs after you shoot a firearm‚ you do not encounter the kinetic energy of the ammunition‚ however

condition that develops in newborns. About one in every 250 babies is affected. Patients with pyloric stenosis present with projectile vomiting in which they are still hungry afterwards. The infant will start showing signs of weight loss‚ dehydration and malnutrition. When my son had pyloric stenosis‚ he had some opposite symptoms that are unusual for infants. He had projectile vomiting‚ weight gain‚ dehydration and mild malnutrition. He was 12 weeks old when we got the diagnosis. They ran an

Determine the velocity of the projectile as it reaches the pendulum. Hypothesis: Firstly‚ we guess that the outcome of the velocity of the projectile is 6.3 meters per second [left].The formulas we use to find the final velocity of the projectile are Trigonometry‚ Kinetic and Potential Energy‚ and Momentum. Mass of the pendulum = 80.0g Mass of the ball = 7.64g Length of the string = 21cm Equipment: Ballistic pendulum device Metal ball projectile Procedure: 1. Ensure that

Three commonly used materials for armouring vehicles and their composition and micro structure are; 1.

Physics Formulas: Mechanics Mechanics is the oldest branch of physics. Mechanics deals with all kinds and complexities of motion. It includes various techniques‚ which can simplify the solution of a mechanical problem. Here are some of the often required physics formulas falling in mechanics domain. Motion in One Dimension The physics formulas for motion in one dimension (Also called Kinematical equations of motion) are as follows. (Here ’u’ is initial velocity‚ ’v’ is final velocity‚ ’a’ is
