longer-lasting golf ball. Therefore‚ the research group at Par has been investigating a new golf ball coating designed to resist cuts and provide a more durable golf. The tests with the coating have been promising. One of the researchers voiced concern about the effect of the new coating on driving distances. Par would like the new cut-resistant ball to offer driving distances comparable to those of the current-model golf ball. To compare the driving distances for the two balls‚ 40 balls of both the new

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

ceramic tile‚ which least affects the dynamics of a bouncing table tennis ball? Background Information: Table tennis is a ball game that can be played on any reasonably sized‚ flat‚ elevated surface. As is the case in any ball game‚ a crucial criterion to base which material to be used as a playing surface is the bounce of the ball. For any ball game to be fair to both sides‚ the playing surface must be such that the ball bounces back to a height that is as close as possible to the original height

felt-tip. Historically‚ reed pens‚ quill pens‚ and dip pens were used. Modern-day pens come in a variety of colors and assortments. The most common contain blue or black ink. I have chosen to analyze three different roller ball pens that dispense a water-based liquid or gel ink through a ball tip similar to that of a ballpoint pen. The less-viscous ink is more-easily absorbed by paper than oil-based ink‚ and the pen moves more easily across a writing surface. The quality of pen components is checked during

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. Gravity is the amount of force that acts upon an object. In this experiment‚ when one projects an object in the air
