or under pumped balls can be detrimental to performance If you do not have the correct amount of air inside of the ball you could possibly blow a game which could end up costing you millions of dollars if you are a professional‚ and it could just all be because of the amount of air inside of the ball you are using. To test this theory‚ you can use a ball for the most popular and played sport in the world‚ soccer‚ to really see if it affects the sport that much and how far the ball goes due to the

Joshua Cooper Jonathan Cooper Tyler Allrutz 1/16/14 Physics Tennis Ball Inquiry Goal Purpose When received this lab we had to come up with an experiment that would have to involve testing two tennis balls but one of the tennis ball had to be altered in one way. The way we tested the tennis ball was by dropping them from a certain height and seeing how high they bounce back up. We then would make a graph and then see the relationship between the data. Once finding the relationship we can

Chapter 11 – Question 24 (p. 351): At the .05 significance level‚ is the number of units produced on the night shift larger? H0: µ1 ≤ µ2 H1: µ1 > µ2 Z critical value: 1.645 x̄d (µ1): 351 x̄n (µ2): 345 σ^2d: 21 σ^2n: 28 Nd: 54 Nn: 60 Z=(351-345)/SQRT((28^2/60)+(21^2/54))=1.302 Fail to reject the null. Z is less than the critical value; therefore‚ the number of units produced on the night shift is less than the number of units produced on the day shift. Chapter 11 – Question

Title: The fastest object to hit the ground Purpose: The purpose of this experiment is to determine if the weight of a certain object affects the velocity of the object when it hits the ground. Hypothesis: If the Buick is projected in the air at the same angle as the other objects‚ then it will have a higher velocity compared to a tank shell‚ a golf ball‚ a baseball‚ a bowling ball‚ a football‚ a pumpkin‚ an adult human‚ and a piano. Introduction: In physics‚ velocity is often defined as the speed

Sheck Mrs. Asofsky Advanced Research 12 December 2012 Got Balls?: Literature Review Anyone who has ever gone bowling must be familiar with the brightly colored balls used to knock down the pins. But few people have ever really paid attention to the science behind bowling and realized how much of an influence aspects of technology has had on the advancement of this intriguing sport. Some people think of bowling balls as “just a ball” but for others‚ bowling is a “serious sport” (Falcioni). To

Having my future in mind‚ she had me experience being a Daisy‚ a Brownie‚ and a Junior. Although I had to endure the pain of walking door to door to sell cookies and calendars to strangers when I could have been on the couch watching Power Rangers‚ being a girl scout certainly had interesting stories to remember

Travis has just lost his part time job and is a peace protester who wants to travel to India with his girlfriend. Barris is a 42-year-old who lives alone with a domineering mother‚ who has made him join the experiment to raise money for her hip operation

EXPERIMENT 1: REACTIONS OF ENOLATE IONS WITH CARBONYL GROUPS Aims In this experiment we used two techniques for the reactions of enolate ions with carbonyl groups. One technique used was Doebner reaction and the other technique used was Claisen-Schmidt reaction. Therefore the aim of this experiment is to synthesize trans p-methoxycinnamic acid and to synthesize dibenzalacetone via an aldol condensation reaction between acetone and benzaldehyde. The products would be recrystallized using ethanol

Introduction A lot of research has been conducted on the physical force naturally involved and the biomechanics that are involved when one is shooting a basket ball. There are positions that work out the best result during the shooting time. They work best due to the force exerted and the angle and tactic used. All these concepts rely on the physical positions and energy exertion areas that are employed. From mid range to long range activities in basketball shooting‚ there are six major points

Experiment 2: IDENTIFICATION OF UNKNOWNS BY TLC AND MP IN COMBINATION Introduction: Thin layer chromatography (TLC) is one of the most valuable techniques in organic chemistry. This is a best method of separating and identifying mixtures of two or more compounds. The separation is accomplished by the distribution of the mixture between two phases: one that is stationary and one that is moving or mobile. Chromatography works on the principle that different compounds will have different
