Physics of the Golf Drive Essay -- physics sport sports golf

This paper examines the physics involved in driving a golf ball off the tee. The objective of a drive is to achieve the greatest distance while leaving the golf ball in the middle of the fairway. Several factors will be considered in achieving the longest, and most accurate drive. The factors include calculating the velocity of the golf ball after the club and ball collide, the mass of the club head, launch angle, the shape of the club face, and finding the optimal golf ball. Intuition tells us that the larger the velocity of the club head at impact with the golf ball, the larger the velocity of the golf ball after the impact. To calculate the velocity of the golf ball we need to consider the relationship between the velocity of the club head to the velocity of the golf ball. If the collision between club head and ball were elastic we would be able to use Conservation of Mechanical Energy and Conservation of Momentum to determine final velocities of club head and ball after collision, but the golf ball undergoes some deformation at time of impact, thus some energy is lost. A simple test of bouncing a golf ball on a solid surface shows that the golf ball does not return to it's initial height. The elasticity of a ball (e) is equal to the proportion of the velocity before collision to the velocity after collision. If the collision was elastic, e = 1. If the collision was perfectly inelastic, e = 0. The value of e is between 0.70 and 0.80. In order for there to be a collision the initial velocity of the club head must be greater than the initial velocity of the golf ball. Also for there to be separation, the final velocity of the golf ball must be greater than the final velocity of the club head. Thus the eq... ...ar Application to Golf.† The Physics of Sports.

Memories of Montreal

The main character begins by emphasizing his regret and sadness In bringing his son up in a posh, serene and wealthy neighborhood located in West Vancouver, that Is vastly deferent from the richly cultured streets of Montreal from which he grew up In. This point is clearly stated In the text with the statement â€Å"And I blame yeses'.He wishes that his son had had the chance to experience the feeling of safety and support that came with growing up In a Jewish community where all the females had similar tragic pasts Involving the Holocaust. Although his childhood may have been less luxurious than his sons he knows that Its our experiences that makes us who we are as a person, and that It was the life skills that he learned growing up In Montreal, that are priceless to him.The father than truly captures the reader Into is fond memories of growing up In Montreal as he describes the Joys that he experienced by expressing the all to familiar sights and scents that he came across while n avigating the bustling streets of Montreal that were lined with all sorts of family owned shops, delicatessens, laundries and corner stores. The main character finishes by reflecting the sorrow he feels for his son as he walks to school, surrounded solely in beautiful showering cherry blossoms and not the influential feel of community, that he once did.
