The hypothesis was rejected for this experiment. The data from the experiment doesn’t support the hypothesis because concrete did not produce the highest bounce. The average height of the bounce on concrete was 104.56 centimeters, but asphalt had a higher bounce with an average height of 108.80 centimeters. The carpet did not compare to any other surfaces because when the ball bounced the bounce died. The weather and temperature outside could of affected the bounce of the basketball on concrete and asphalt. During the experiment on a few surfaces, it was very hard to be able to hold up the tape measure to measure the bounce. There weren’t that many problems with the experiment, but there were a few. When I dropped the basketball it was very
Healey moistened the footballs because during the game it was roughly fifty degrees and there was a large shower of rain. When he did this the PSI dropped by about two, just like the Patriots' footballs that went from twelve and a half to ten and a half. More evidence also proves that some academic and research physicists now admit that they made an important mistake in their original calculations. After the error was fixed the amount of deflation predicted in moving from room temperature to a fifty degree field is roughly doubled. Healey measured the drop in twelve footballs that were moved from a seventy-five degree room to a fifty degree area, just like the Patriots. (Glanz,
When two objects slide across one another, they exert a frictional force against each other. These forces are always tangent to the surfaces. A soccer ball and its interaction with the field is an example of this. The frictional force is opposite the direction that the ball is traveling. Physics gives us the following equation: f=mN for objects that slide against one another; where the frictional force (f) is equal to the upward "normal force" that the surface exerts on the ball (N) multiplied by the coefficient of friction (m). The coefficient of friction is not a constant, but will vary with the ball and surface type. The more friction there is between the ball and the field, the slower the ball will move after a bounce. Balls that skid, on the other hand, do not generate as much friction and subsequently do not slow down as much. So, the coefficient of friction tells us how fast (or slow) a ball will travel: The higher the coefficient, the slower the ball. A device similar to the Stimpmeter®, which is used to measure the "speed" of a golf green, could measure a soccer field's coefficient of friction by rolling a small ball on grass and measuring the distance it travels before stopping.
will bounce to after having a loss or gain of energy due to sound or
BANG! THUD! FLOP! The usually sound of an athlete when they hit the ground after they received and unexpected injury during the middle of a big game. While reading The Glass Castle, Jeannette Walls went through adversity in her life so too must athletes who get injured in sports. It happens in sports everywhere: professional, college, high school, middle school, and even in younger age groups. Injuries aren’t fun, but that’s just how the dice roll. Those who don’t go through injuries are blessed with knowing that they don’t have to go through the hardships; however, they are also cursed because they don’t know the feeling of breaking your ankles in a soccer game, receiving a concussion during a football game, or even breaking your arm during
The more and more I look around I begin to see how physics are integrated into practically everything that we do. These things would surely go unnoticed without making a conscious effort to notice them. For example simple things like riding a bike, or driving a car, or playing catch with a son or daughter. Just as these activities are loaded with elements of physics, sports are also, especially basketball. Physics play a part in every aspect of the game, from dribbling, passing, and shooting, to things as simple as setting a screen. First we should take a look at the elements of dribbling.
This investigation was conducted to determine if different soccer ball sizes affected the distance each soccer ball would travel when kicked. The hypothesis was that If the sizes of the soccer ball are changed, then the ball with the smallest size will go the farthest because, it has less air and weighs less than larger soccer balls. The results of this investigation did not support the hypothesis. The size 4 ball travelled the greatest distance compared to the largest and smaller soccer balls.
B) the pavement because the normal force from the pavement causes an equal force on the ball, which makes it bounce.
To investigate the affect the material of a ball has on the bounce height of that ball where the drop height (gravitational potential energy), temperature, location, ball, and air pressure of the ball are kept constant.
I developed my experiment because I like to exercise. The experiment was also developed because I like to learn how the brain works and if exercise would actually increase you memory.

On the surface, basketball has a number of impacts on young people. For instance, the boys and girls who participate in basketball learn certain positive character traits. There is evidence to suggest that because of participation, they have a better attendance in school, better grades associated with good behavior in school, and less trouble and rarer discipline issues. In addition, students also have better citizenship in school as well as the community, and an upward mobility orientation like joining college later on in life.
The rebound is affected when someone puts spin on the ball. When the ball is spun to the right when thrown at the backboard, the ball will go to the right. When it is spun to the left, it will bounce off of the backboard and go to the left. This is why players should put backspin on their shot, because when they miss long, there
Basketball is a extremely hazardous sport that involves rigorous amounts of jumping leaping and running. The basketball goal is often gloried due to the fact that it is the scoring avenue in the game of basketball on the contrary; the hazard that are associated the basketball goal itself can be monumental. The padding that is around the goal post of be a monumental asset to the establishment of safety when play the game of basketball. “Bucyrus High School junior Noah Lear died Wednesday two weeks after he was severely injured while playing basketball. Lear was playing basketball on Feb. 27 with three of his friends when a dunk attempt snapped the support pole causing the pole, backboard and hoop to come crashing down, landing on his head
The horizontal displacement will be measured using a tape measure at location of the first impact (the watermark left on the basketball court).
According to the rules put forth by the USPTA, when this ball is thrown from a height of 6 feet, the bounce should not be less than 31 inches or more than 33 inches.
