A round, inflated ball,around about 27 inches (78 cm) in circumference, used in this game called basketball The basket balls have to go through four separate stages . At first the inside of a basketball is a bladder. To pass the first step they have to stay inflated for twenty four hours. The bladder is round. They use a special kind of rubber called butyl rubber. A machine helps to write on the balls to put the letters on it. Some balls are made with higher quality thread. Some basket balls are made with different materials.then cut into six separate panels. then the material is glued with a special type of glue. When they're finished they are around twenty nine point five inches. Finally, they have to go through a final process to get
checked.And they must bounce to a certain height.When dropped from 72 inches they must bounce 52-56 inches high. They are usually used for pro games and teams like for example the boston celtics and the cleveland cavaliers and the LA clippers`
Basketball is defined as a game where two teams of five play each on a rectangular court, usually indoors (Basketball/Sport). Basketball was invented by James Naismith on December 1, 1891 (Basketball/Sport). The object of basketball is to shoot the basketball through the opposing team’s basket and to out-score them by end of the regulation time limit. If the score is tied at this time, the game will go into overtime until one team wins. While reading about basketball, I found it interesting that when the sport was invented they would nail baskets to balconies with no backboards. This made it easy for spectators (in the balcony) to help their team by either swatting the
Make another ball, this time a bit smaller than the first, and make it a different color. Mold it into a triangle, and lay that aside. Try making patterns like stripes, with another color and mold it together. This part will be your shirt/pants. Do not attach it to the head yet.
If you think about it, it’s almost impossible to measure the force that it takes to dribble a basketball, unless you have the right tools. Let’s just think about the basic physics that you should know. In order to dribble a basketball you need to apply enough force for the ball to go from your hand to the floor and back up to your hand. When the ball is in your hand it is holding potential energy. Potential energy is the energy that is about to be transferred into kinetic energy, which is when the energy is in use. The ball is in kinetic energy after it leaves your hand and starts to fall. So the force of gravity has to be less than the force of the bounce to keep the dribbling going.
Dribbling If the basketball was simply dropped from a height of 1 meter with no initial push from the dribbler and rebounded from the floor in a perfectly elastic collision, Mechanical Energy for the system would be conserved (1). However, the collision is not completely elastic and the dribbler pushes the ball with an initial force to ensure that it returns to his hand. To simplify the process I will first consider a situation in which the ball is allowed to fall freely from a height of 1 meter and has a perfectly elastic collision with the floor. After that I will take the true nature of the collision with the floor and the force applied by the dribbler into consideration.
How does the air pressure inside a ball influence the bounce height/vertical motion of that ball?
Have you ever asked yourself how much energy or effort it really takes to dribble a basketball? Energy can only mean one thing: the strength required in a physical or mental activity such as basketball. Every time someone would bounce a basketball on the floor it has to transmit energy for the ball to come back into the air, or into your hands. Without the force of energy, you couldn’t handle the ball like the way you’re supposed to in the game. Why is it when you stop dribbling a basketball, the ball stops bouncing? Being a basketball player requires you to put force onto the ball, to make the ball bounce. Every time you dribble the ball energy is required. In this experiment you will see how the ball bounces on different surfaces such as wood, cement, and carpet will influence the height of the ball itself!
Before I talk about the interview it is necessary to illustrate you with the differences in able body basketball and wheelchair basketball. The rules of wheelchair basketball and stand up basketball are very similar. The quarters are the length of 12 minutes. The shot clock is 24 seconds and once the ball hits the rim it resets. When the ball is in play you have 8 seconds to cross half court. Players can only be in the key for 3 seconds unless if the ball is being shot. When a player is inbounding the ball you have 5 seconds to pass the ball in. The major difference between these two sports are traveling, which happens when the players pushes his chair more than 2 times without dribbling the ball. There are four types of fouls like basketball.
... air, just remember that it takes the same amount of time for him to reach the basket as it does for him to fall. You may also want to notice how the ball spins as well as how it bounces. As you are watching the playoffs this year keep in mind that the application of physics is very much at work in the game of basketball.
Tennis balls are made of two concave rubber halves which are cemented together, the cover is made out of a combination of wool, synthetic fiber,(which is often nilon) and the seams of the tennis ball are made out of stitches.
In both sports, training, having a good season, using appropriate uniforms and equipments are needed. Both sports use uniforms, sports shoes, water bottles and an adequate weight to train. However, these sports have some significant differences as well as similarities. One of the differences is the net. In Basketball, for example, the hoop is 18 inches in diameter and 10 feet high located in both sides of the court. On the contrary, the net in Volleyball is 39 inches tall and 32 feet long; this provides one foot of netting on each side of the court. Another important difference is the ball. In Basketball, the ball has an inflatable inner rubber bladder wrapped in layers of fiber and covered with a tacky surface made with leather, rubber, or
Now days they are made of rubber or a water proof material which helps the players get a good grip on the ball. Also the balls are made of panels on them which help improve the flight of the ball in the air. The colours of the balls have evolved. The balls started of with brown, then orange and then went two- tone in white and black until an all white ball was chosen. Now the balls are multi coloured from green, blue, pink well basically every colour. The main ball supplier is Gilbert.
There are many different types and brands the most common brands are Wilson, Head, and Babolat. Tennis balls have been made out of cloth strips stitched together with thread.Tennis balls are now made of hollow rubber with a felt coating.
Many coaches throughout playing basketball will tell their players to anticipate where the rebound will go. Most of the time the basketball will go on the opposite side of to goal from where the player shot from, if it was not shot perpendicular to the backboard. There are many actions that can affect the rebound, the spin of the ball and the shot itself. The farther out the jump shot is taken, the longer the rebound, because if the shot is not on line, the ball will bounce off of the rim (Kendridge, The Physics of Basketball).
tracker balls the palm of the hand, is used to roll the ball in any
The mass, density, and volume are also a part of the way the ball bounces. The mass of a tennis ball is between 2 and 2 1/16 which is 57.7 and 58.5 grams. Who knows because different companies that make tennis balls make their balls in different ways. The volume of a tennis ball is about 8 cubic inches. This makes the density fall between 0.44013375242 and 0.4462361268 grams.
