How high does a ball bounce? Aim: To see how high the bounce of a ball is. The changed variables are the height of where the ball is dropped from. The independent variables of this investigation. The (dependent) variable that will be measured in this investigation is the bounce height of the dropped ball. This shall be observed with one person dropping the ball from above while another person watches the for the highest point the ball reaches. Three variables that could be affected

Steel ball is widely used in machine‚ but also ages rapidly. Therefore‚ knowing the ball mill course and causes of aging can improve the life span. There are four major causes of steel ball aging Firstly‚ cutting and shaping abrasion. The relative sliding motion in the cylinder of ball mill ball is in the rising phase‚ hard material by the group is in cutting groove‚ and cutting softer materials on the ball is of the relatively shallow. Materials produce local shaping abrasion of the

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

fairway is able to strike a ball so that it leaves the club with a horizontal velocity of 20 m s–1. (Assume the acceleration due to gravity is 9.80 m s–2‚ and the effects of air resistance may be ignored unless otherwise stated.) a b c d e How long after the ball leaves the club will it land on the fairway? What horizontal distance will the ball travel before striking the fairway? What is the acceleration of the ball 0.5 s after being hit? Calculate the speed of the ball 0.80 s after it leaves the

object in motion to remain in motion. But because of gravity the ball is pulled down and resistance that slows the ball down. A quarterback through the motions of his and body‚ must balance the forward momentum that he gives the ball‚ fighting gravity and air resistance that pulls and slows it down. Aerodynamics is involved during passing because of the spin that is applied. The better the spin the straighter and further the ball will travel. This is accomplished by the quarterback throwing the

ever said ‘When Life Brings You Bowling Balls’? Nope! Never. The say would never catch on and it made Olly the Bowling Ball miserable. He was an adorable little ball. He was painted a neon green colour. His paint was chipped and faded. As the years went by‚ Olly became the unused bowling ball. It made him cry. His other bowling ball friends were upset for him‚ though were just glad to be getting used. There was a rule at the bowling alley in which the balls resided. If you were not used over the space
