In this lab experiment, I experimented with 2 different amount of borax (1g and 5g) to see if the amount of borax affects the bounce height of the ball. The ball is made up of polyvinyl acetate (school glue), borax and water. In the experiment the independent variable is borax and the dependent variable is the bounce height. I found out that borax has sort of a protective layer that creates the bounciness. Therefore, I hypothesized that the more borax that is used, it would be more bouncy, because there is more of a protective layer to it. My hypothesis was right, because the result that I got was an average bounce height is 39.8 cm for the 1g of borax and 46.6 cm for the 5 g of borax. The result shows the significant different between the 2 different amount of borax added to the ball. Even though some of my trials are a little off, my average bounce height in cm is around the range of the more precise average which is the grade’s average and class’ average. …show more content…
All of the average is around the same range, but the grade average is more precise since there was a total of 190 trials for each. In both of the average it is consists of the same factors such as the units, drop height, and the quantities. Even though the averages are pretty accurate, there are factors can have gone wrong while conducting some the
If the height is two and the other side length is an even number then use this equation: (x/2)-1 = rebounds (EX. 2 by 6, do (6/2)-1= 2 rebounds) If that doesn’t apply, and one side length is half the length of the other, then the number of rebounds is 1.(EX. 4 by 2) If that doesn’t apply, and one side length is 1, then subtract 1 from the other side lengths and that is the number of rebounds.(EX.
How does temperature affect the bounce of a tennis ball My science fair project is about tennis balls and temperature. I chose this topic because I am interested in how temperature affects how high a tennis ball bounces. When the ball hits the floor it expands and when it comes up then it comes back up it contrasts. My question that is going to be answered is,how does temperature affect the bounce of a tennis ball?
The goal of the experiment is to synthesize a bromohexane compound from 1-hexene and HBr(aq) under reflux conditions and use the silver nitrate and sodium iodide tests to determine if the product is a primary or secondary hydrocarbon. The heterogeneous reaction mixture contains 1-hexene, 48% HBr(aq), and tetrabutylammonium bromide and was heated to under reflux conditions. Heating under reflux means that the reaction mixture is heated at its boiling point so that the reaction can proceed at a faster rate. The attached reflux condenser allows volatile substances to return to the reaction flask so that no material is lost. Since alkenes are immiscible with concentrated HBr, tetrabutylammonium bromide is used as a phase-transfer catalyst.
In that they are better than aluminium alloys and wood because they are more durable, they have a much better weight distributions, there is an improved trampoline effect and to control hand sting they have a higher damping rate. As the bats give an advantage to improve the trampoline effect over a period of time, it made the NCAA to scrutinize the bat as they were giving an unfair advantage to the players. When they were tested they showed that the performance standards were above the accepted ball exit speed ration and this was after they already broken in. This made to a new measure to be introduced, which was batted-ball coefficient
Well you can find out by reading the rest of this paper. “Where does a basketball bounce best. ”Why do different surfaces affect how high a basketball bounces? Different surfaces affect how high a basketball bounces because different types of surfaces absorb more energy than others.
Elijah Brycth B. Jarlos IX-Argon 1. Multicellularity is a condition of an organism to have multicellular cells. An example of a organism who has multicellular cells are plants, animals, and humans. The main reason of why scientists have a hard time finding a good set of existing organisms to compare. Is neither the first set of organisms which is being compared is dying as fast as the second specimen is being examined or they just can’t find the right species.
In conclusion, air pressure has a direct influence on the distance that the ball will travel when thrown. The hypothesis stated that if pressure is added to the football, then the distance the ball projects will increase when distance is a function of pressure. Based on the data that was collected from the experiment, the hypothesis was supported. When the football had more air inside, it went the farthest distance compared to the other two pressures that data was collected from.
Answer: The AlleyOOP Variable Bounce promise the best in quality, performance, and safety. The Double Bounce system has two jumping surfaces divided by 8 inches of space which acts as an additional shock absorber. Question: How heavy is the double bounce 14 ft trampolines?
Omar Fahmy Ms. Mao Physics 02/23/15 Physics Behind the “Pill” Research Question: How do the physics of a rugby ball suit the specific needs and characteristics of the game? Picture: General Information: Rugby, a sport not known to many, and mainly prevalent in the southern hemisphere, is a game known for its teamwork, cooperation, agility, and violence.
The low mass weight can be in many different shapes and densities. It is placed more in the center of the bowling ball. This would be the kind in the Reactive Resin and the Particle Proactive because they tend to have a big curve or
In this egg drop project, a container was built to house one egg and was then dropped at various heights. The purpose of this lab was to find how impact time affected the force with which an object, the egg container, hits another surface as the momentum moves to zero. Our hypothesis states that if the impact time is stretched longer then the force exerted on the egg would decrease, making the egg less likely to break. The independent variables for the egg drop project was the height at each drop; the dependent variables were impact time and survival of the egg. The controls were mass, design of the container, and the egg.
We did squat jumps to strengthen the muscles in our legs, to give us more power and more stability we jumping to intercept the ball. (M) An example of Specificity today was medicine ball chest throws. (A) It will help us in netball because this would improve the power of a chest pass as that is the most commonly used pass in netball.
Bouncing may be a significant segment in the material science behind basketball. As a basketball player hops circulating everywhere to settle on An shot he could show up with make suspended to mid-air Throughout the high pitch of the bounce. This may be an outcome about projectile movement. When a article is tossed buzzing around it will Invest an extensive rate of time in the Main and only the Toss. A b-ball player could hop to the extent that 4 feet buzzing around (vertically).
Its material and light-weight allows air resistance and its spin to have significant effects on its motion when airborne. Air resistance is the result of the projectile’s leading surface colliding with air molecules, and it is affected by the velocity of the object and its cross-sectional area. Specifically, a higher velocity and greater cross-sectional area results in greater air resistance. Additionally, ping pong balls allow bounce quite high when they strike a surface. 3.1.2 Physics of projectile motion Since the launcher will launch the ping pong ball so that it launches with a parabolic trajectory, the physics behind projectile motion comes into play.
DEFINITION AND DESCRIPTION OF THE TASK The researcher will conduct an inflated balloon experiment. This experiment will allow the audience to understand clearly, "Charles' Law" and "Kinetic Molecular Theory" respectively. It will use extremely low and extremely high temperature so that the audience can evaluate the significant difference on the balloon size. The students shall be competent in presenting a laboratory experiment because it is one way to get involve in the lessons taught in school.
