In the fall of my sophomore year of high school, my brother had just made the soccer team so you could find us in the backyard kicking a soccer ball around. We would pass, practice corner kicks, and shoot for hours. Sometimes our sister, who was about five at the time, would join us, which mostly slowed things down. One fall afternoon after school, we were kicking the ball around and my little sister decided she wanted to play. She ran about ten feet in front of my brother for a pass and he waved for her to go further back. He continued to wave her further back until she was at the other end of the yard, about 30 yards. My brother kicked the ball pretty hard and it started to curve. My little sister noticed the ball moving extremely fast in her direction so she started to run away from it. Since the ball was curving to the right and that was the way she was running, it looked as if the ball was chasing her. Even with her great efforts to run away, the ball hit her and knocked her off her feet. My brother and I couldn’t help but laugh at how hard she tried to get away, but with the curve of the ball, she ran right into it. From that moment I have wondered what the physics were to the ball curving. Why does a soccer ball curve in some instances and not in others? What …show more content…
The ball is going to move or curve in the direction of the lower pressured side because of the Magnus force. According to physicsbuzz.physicscentral.com, “Whenever a ball is spinning through the air, the Magnus ‘force’ will push it in a direction perpendicular to the direction of movement”. In our example before, the airflow on the right side of the ball will move in a forward direction and slightly downward. While the airflow on the left side of the ball experiences friction of the airflow and the rotation in opposite directions, a force is created “perpendicular to the direction of

This report focusses on the 3 energy systems of fitness before relating them to touch football. Touch football is a simple but fast paced game, where the main objective is for one team to score more tries then their opponent. Scoring a tri is achieved by placing the ball in the opponents ‘tri zone’. Played on a 70m long by 50m wide field over a 45-minute time period, the game consists on two 20 minutes blocks of play with a five-minute half time break.
There’s different ways to kick a ball, you can kick it normally, you can curve it, knuckle it. I am going to try my best to explain how to kick a ball normally and some of the other examples. The 1st step is step back a few steps like about 4. Step 2 and this is optional is to look up when you are about to strike the ball this is for to see where the goal is and where you're going to aim.
The higher the pressure, the harder and more firm the football becomes. Conversely, the lower the pressure, the more give the ball has, potentially making it easier to catch in cold, slick weather. But lighter balls are also more influenced by air resistance. (Pigskin Physics)
Can you bend it like Beckham? With the right training, skill, and knowing more about the soccer ball, the individual will! The soccer ball is a very interesting object. A soccer ball has to have a certain amount of air pressure in order to work properly. The air also affects the soccer ball’s flight. The soccer ball is also made of different kinds of material and has different sizes. In the next couple of paragraphs I will tell you more about a soccer ball and the air pressure.
In touch football the human body uses energy systems. The definition of the energy system is, an energy system is a system primarily designed to supply energy-services to end-users. The human body has three energy systems they are ATP-CP, Anaerobic lactic and Aerobic energy system. For the human body, it requires the energy systems because if the human body wants to do any physical movement it will need convert high energy which is also called ATP. The ATP will be converted to low energy.
Touch Football is a team sport consisting of 6 players split into two teams on the field at a given time. It is a high intensity game, involving bursts of maximal speed and power. During a game of Touch Football, all three energy systems work towards energy production required for muscular contractions, however the dominant energy system is determined by the intensity and duration of the effort performed.
There are six steps in an instep soccer kick that are shown in the diagram above. In the approach phase, the player is running up to the ball (which is at rest) and gaining forward momentum. This is an example of Newton’s first law that states that “an object at rest stays at rest and an object in motion stays in motion with the same speed unless acted upon by an unbalanced force”. The soccer ball is going to continue to stay at rest until it is moved by the person. The second phase is when the player plants their foot, in the direction that they want the ball to move after they kick it.
There are three main energy systems used in a game of touch football which consist of the creatine phosphate (ATP PC) system, lactic acid system and the aerobic system. Each system plays a vital role during game play. Every muscle in your body requires energy to perform all movements, and to do this, the energy is produced by the breakdown of a molecule called adenosine triphosphate (ATP). ATP is found in all cells which is a chemical form of muscular activity and performs mostly all functions in the human body. It contains 3 phosphate groups and adenosine. ATP is stored in the muscles and lasts for approximately 10-30 seconds. Carbohydrates, fats and proteins, are all producers of ATP from the food we eat; however Creatine Phosphate is
In my paragraph i will be talking about Galileo and also about the effect of the football when it's getting kicked. I learned that Galileo was the one of the first people in the western side to realize that the shape of the curve is something mathematiicians had been talking for a couple of years, it's called a parabola. According to the video, the video thought me something new, I never knew that Galileo discovered that the curve of the ball is called a parabola. This helps me understand how projectile motion. Once the kicker lets go of the ball and starts getting ready to kick it, the ball has to stay leveled or the nose of the ball has to be slightly up. As the football flies through the air in the shape of a parabola, there are two components
The ball uses this kinetic energy to move up the usually 6 to 7 degree incline to the top of the playing field. The kinetic
The four main steps to curving a soccer ball are setting up, correct position, foot placement, and the follow through. To start us off, the player learning to curve the ball must get everything set up. The preferred ball to use when learning how to curve would be a ball famous for curve, or a match ball from preferably Nike or Adidas. When the player has found the

There is no question that everything people do in their lives involves physics. This is true from the way we communicate to the way that we fight wars. In some cases the influence of the laws of physics on our world are extremely apparent, such as in sports. Basketball, hockey, baseball and even cricket involve physics. From the most basic motions players perform in the game, to different plays designed by coaches, physics touches it all. These appearances of physics in the games that we play are sometimes so subtle we don’t even notice them. In other cases however, the impact of physics can be heard across the stadium as Jerome “The Bus” Bettis barrels his way into the endzone. The influences of physics on
The distance that you are able to kick the ball can be summed up with the equation for distance, d=RT, distance equals rate multiplied by the time. So speed and time are both very important when kicking the ball because it directly affects the distance. Soccer players vary the distances that they want to kick the ball. Skilled players can estimate very quickly how fast to make the ball move to make it go where they need it to. Before learning this equation in physics I just thought you kicked the ball, but now I know that when this equation is applied to soccer it means so much more. Soccer players can use this to help them judge how hard and fast they need to be able to kick the ball to make it go a certain distance. This is just another example of how physics, the small details, can be used to improve ones soccer skills.
