Data Acquisition Case Study

During the bounce test, the ball may have been released from different points. Although it was supposed to be released from its bottom, human error may have compromised the precision of this measurement. To improve the design of the bounce test, the ball’s bottom point should be marked, and the ball should always be released from there. During the ramp test, the ball may also have been released from different points. Although the ball was supposed to be placed on the ramp so that it would be released from the front, human error may also have compromised the precision of this measurement. In addition, human error may have caused unintentional and unnecessary force applied to the ball. To solve these design issues, a door should be made that holds the ball at a certain position for a fixed amount of time before the experimenter released the ball. During the catapult test, the ball may have been held back for an excessive amount of time. To resolve this experimental design issue, a fixed time to hold the ball back should be

Skateboarding has rich history of innovation and is full of intriguing stories. Many of these stories are documented in this book in great detail. However, this essay will provide you with an overview of the last nine decades.

In this series of experiments, we examined the back and forth motion. We analyzed the motion of five objects which included a mass attached at the end of a spring, a swinging pendulum, a ball thrown up in the air, a jumping student, and a cart rolling up and down an incline. Using the motion detector and a computer we were able to come up with graphs of position VS time and Velocity VS time from which it was possible to tell where the velocity or the acceleration were maximum, and whether they were changing or not. Besides that, the graphs also helped to notice objects that exhibited a similar type of motion.

Skateboarding has been around since 1944. Initially, created as a crate with wheels and a bar used as a handle bar, the idea was slowly being more refined. Woman’s Army Corps Betty Magnuson, reported seeing French children riding on wooden boards with rollerblade wheels attached to them which would imply that the idea has been played around with but never capitalized upon. From crate boxes with handle bars, to popsicle shaped boards with specialty made wheels backed with a massive culture, skateboarding has become a popular industry.

Skateboarding is the act of riding and performing tricks using a skateboard. A person who skateboards is most often referred to as a skateboarder, or colloquially within the skateboarding community, a skater. Skateboarding can be a recreational activity, a job, or a method of transportation. Skateboarding has been shaped and influenced by many skateboarders throughout the years. Skateboarding is relatively modern.

In this experiment we first tried to find an experimental value for g. This was done by dropping a golf ball below a sensor that would read and chart the position vs time graph and the velocity vs time graph. From this we could receive an equation and numbers that are useful in finding the velocity and acceleration of the ball in order to find the experimental g value. Then we did another experiment in which we would hold out a ruler between another person's index finger and thumb and then drop it, measuring how many centimeters it took for them to catch the ruler. Using this and an equation we could measure their reaction time.

Our group has always enjoyed baseball, we decided to make our video on the biomechanics of a baseball swing. We all are fans of the sport, it’s America’s national pastime, and we also know there has been extensive research on this popular movement. The game of baseball was invented in 1839, by Abner Doubleday, in Cooperstown, New York. Ever since that day, the complexity, yet simplicity of the of the hitter’s swing has intrigued the players, fans, and certainly the researchers. As the years passed, we developed technology the further investigate the biomechanics of a baseball swing. Tony Gwynn was one of the first hitters to ever carry a camcorder with him everywhere, falling in love with studying his swing. With the emphasis being put on

Values are expressed as mean ± SD. By identifying an ice hockey player’s fitness level, VO2 max values, lactate threshold and anthropometric physiology, improvements can be made to the athlete’s physical performance. Activity Analysis: Ice hockey is identified with high-intensity sporadic skating, quick changes in directions and velocity, and frequent full-body contact (Lee, Lee, & Yoo, 2014). At the collegiate level, game play consists of about 30 to 60 seconds of intense moments of play, rotated between four forward lines, or groups of players, and three defense pairs for about sixty minutes of play.

The methods of data collection I will use to analyze Carolyn’s movement skills in the fouls shot are a digital camcorder recording of sagittal plane of her dominant side, also frontal plane view. I will use Coaches Eye, a video recording application. Three times will be recorded for analysis. I also will physically record on a chart. My limitations will be the environment because I will have to conduct this analysis outside of a gym, so I will not have a basketball hoop but I will have a goal for Carolyn to aim for. With this data that I will apply it to what I have researched about gaining and practicing the best skill for the ultimate performance. Then I will have my subject Carolyn practice and then re analyze her movement’s.

(“Jim Coleman Synopsis,” 2011). An Immediate Feedback Video System is an innovative system that allows you to view yourself after you pass, set, or hit a ball (Immediate Feedback Video System In Training, 2001). “It is now possible to insert a “pause” between the recording of the action and viewing of the action on the T.V.” As Person 1 hits the ball, it is being taped. After that, Person 1 would walk to the monitor to watch themselves while Person 2 is being taped. While Person 2 walks to the monitor, Person 1 gets back in line and Person 3 gets recorded hitting. (Immediate Feedback Video System In Training,

The external and internal forces acting on the human body and the effects produced by these forces is known as the study of biomechanics, it is a very crucial part in sports as it can help detect inadequacy of any physical technique performed, result in enhancing an athlete’s performance. I will be biomechanically analyzing my own volleyball spike.

Even though skateboarding seems like a dangerous or tricky sport; it is a great mode of transportation and keeps you in awesome shape too. Skateboarding can be practiced for competition, or it can be something people do just for fun! “Skateboard Safety” says, “Skateboarding is a fun and healthy sport that can give you a low-impact aerobic workout” (Safety First). That being said, skateboarding can also be used as a fun, new way to get a workout in or even a different and more enjoyable method of transportation. It is definitely an extremely useful and easy to learn sport! Skateboarding also has many advantages and disadvantages.

Projectile 2 Lab Report Kelsy Ecclesiastre and Sara Lopez AP Physics 1 Period 6 Objective/Purpose: To correctly identify the range of a projectile when fired above the horizontal axis with only a meter stick (i.e. no timer). Background: According to Henderson, speed is how far an object travels during a specific amount of time and does not include the direction.

Jumping is a fundamental aspect of several activities (Aragón-Vargas and Gross, 1995). Sports which requires an athlete to hit an object – i.e tennis, intercepting the path of an object –i.e basketball/volleyball , or even jumping over an object such as high jump, needs an important skill, which is a Vertical jump. The primary goal of a vertical jump is to generate maximum force to reach the greatest possible height (Psycharakis, 2012).

METHOD: An air hockey table was set up and a video camera on a tripod was placed over the air hockey table. The camera was positioned so it was directly above the air hockey table facing downwards. The air hockey table was turned on and two near identical pucks were placed on the table, one at one end of the table and one in the centre. The puck at the end of the table was launched by
