The purpose for the students of the Energy of a Tossed Ball Lab involved learning how to measure the change in kinetic and potential energies as a ball moves in free fall. Since there is no frictional forces working on the ball the total energy will remain constant and the students will see how the total energy of the ball changes during free fall.

Activity 2 ( Energy of a Tossed Ball: Physics with Computers) weighing the rubber ball that was to be used. Then, the members predicted the graphs for the potential energy versus time of a ball thrown vertically up from a height of 50 cm., graph of kinetic energy versus time of the same ball, graph of total mechanical energy versus time of the same ball. The members then placed the motion detector protected with a wire basket on the floor. The file “16 Energy of Tossed Ball” was opened and a member held the ball directly above and 50.0 cm from the motion detector while another member tossed the ball straight up while the motion detector began to collect data. The graphs obtained using Logger Pro were then compared to the predicted graphs.

The final graphical comparison we can make is the total mechanical energy of each of the basketballs, as seen in Graphs 6 and 12. The total mechanical energy is simply the sum of the kinetic energy and potential energy of the basketball. The shape of the graph is a plateau of flat near-constant mechanical energy during the air-time and sharp decreases with a rebound to a lower plateau after each bounce. As seen in the graphs for kinetic and potential energy, the well-inflated basketball had a value of total mechanical energy of 3.45 Joules when it was in the air after the first bounce and the less-firm underinflated ball had a smaller value of only 2.90 Joules after the first bounce. These values are equal to the potential energy of the basketballs at that point in time because the only energy of the basketball while it is in the air is potential energy due to gravity, the mass of the ball, and the height of the ball. The total mechanical energy also had sharp decreases down to zero total mechanical energy during the bounces as both the kinetic and potential energy are at zero. Since the total mechanical energy of the basketballs is close to the value of the potential energy of the basketballs, we can draw the conclusion that the trend of the firmer, well-inflated basketball had a smaller rate of decrease of mechanical energy in between bounces than the less firm, underinflated basketball. These decreases in total mechanical energy after bounces along with the small

No significant problems or difficulties were encountered when carrying out this experiment. The accuracy and reliability of the results and conclusions are very good. Even though I have outlined the inaccuracy's of the experiment, these are only t be expected and do not have much impact on the overall conclusion.

Science Buddies of Scientific American completed an experiment on high a basketball bounced on at least two different surfaces. The conductor explained the types of energy, kinetic and potential. They measure a wall up to forty inches high, typing at every eight inches. In the study, the Science Buddies concluded that when a ball is dropped at the same height and way that it bounced higher on a harder surface than a

It embodies the basic biomechanics principles that most players go through when they are shooting a jump shot. Each player’s could be evaluated differently. This was simply a summary of a natural jump shooter. Biomechanics can be used to assess a player’s ability to shoot accurately and consistently. This analysis did not focus on what a correct shooting form is.

1. Soccer is one of the most demanding of all sports. The game is played on one of the largest fields of any sport, for the longest sustained time and with the least amount of breaks. Players in a soccer team are in continuous activity as they compete for loose balls, move to encourage teammates, rotate positions and run to make a space or test opponents. Running, jumping, sprinting movements in relation with sudden changes of acceleration and route outweigh the play. The power of the game ranges between low-level activities such as walking or jogging to ones of high intensity such as sprinting . This is what is known as intermittent exercise. The rhythm of soccer is dynamic and constantly changing, which is a characteristic that divides it from other endurance sports , this suggests that in order for a midfielder to successfully endure for the entire 90 minutes all three energy systems assist in different stages although the ATP/PC system is dominant.

It can be seen that if an athlete choses to use the tools of sports phycology they will effectively increase their sporting performance and ability. These tools have helped me to improve volleyball ability and

One night, after a long day at school, it was time for basketball practice. As usual, the team got dressed and ate something fast before having to be out on the court. We all started stretching and warming up, waiting for the actual training to begin. All of us knew that in order to play well on game day, we needed to practice even better.

While conducting the ballistic pendulum report you gain a bigger understanding of velocity and momentum. Using the ballistic pendulum, and formulas learned in Physics, one can predict the range of the ball when it is shot horizontally. There are several materials that are used to conduct this experiment including: the ballistic pendulum, a balance, at least one sheet of paper, weights, and a calculator.

During the December lull between seasons of football and baseball, James Naismith, a teacher at the International Young Men’s Christian Association in Springfield Massachusetts, was presented with the task of maintaining the physicality of forty plus students (Cantwell, 2004, 1075). During the 1890’s there was no official sport or popular indoor activity that could help maintain the stamina, health and condition of football, baseball, and track athletes during his or her seasonal break. With the prospect of inventing a solution to this dilemma, Dr. Naismith took on the idea of coming up with a valid up-tempo indoor game to maintain and improve athletes’ levels of fitness during the winter months (Cantwell, 2004, 1075). With his mind and thoughts churning, Naismith pulled from deep down into his memory bank, scratching the surface of his childhood days in Canada farmland and recalled to mind a simple game that he used to play when he was a young man; “Duck on a Rock” (Cantwell, 2004, 1076).

There are many aspects to the game of basketball and physics can be applied to all of them. Although to be good at basketball it is not necessary to play it from a physics point of view. Basketball players become good by developing muscle memory for the actions that must be performed in the game of basketball from years of practice. Nevertheless knowing some of the physics in the game of basketball can help a good player be a better player. In this paper I will cover the three most important aspects of the game, shooting, dribbling and passing.

This study analyzes the use of biofeedback in basketball players and the effect on their on-court performance. Athletes need to have the capability to modify, learn, and correct their muscle memory. Enhancing an athlete’s performance depends on the ability for the central and peripheral nervous systems to communicate in response to an active stimulus. This study has some variables measured including the reaction time: the time between the stimulus and a bodily movement; the movement time: the time taken in the middle of the onset and completion of the bodily movement; and the response time: the aggregate time of the reaction and movement. There have been previous studies that look at the use of Electromyographic Biofeedback (EMG BFB) and Electroencephalographic Biofeedback (EEG BFB) and found correlations between improvement in performance and responsiveness to stimuli. However, there has not been an analysis of the use of Heart Rate Variability Biofeedback (HRV BFB) which measures an increase in the response time and attention deficit in athletes. The most important aspect of an athlete’s performance is the ability to tune out outside disturbances during a game or match. If an athlete can master that skill, then they can perform at their optimum output. Having the ability to enhance their techniques is important for achievement in sports, especially in basketball, where there are a multitude of offensive and defensive skills. Most notably,

The setup involved three of paper with low conducting teledeltos paper on top to allow the marker to locate the potential at different points between the parallel plate. The power supply provided the potential difference of 10V between the two plates and thus etched marks
