Physics in Sports Essay
Everything from kicking a dinner gown into a goal to running from one side to the other side of the field is based on physics. natural philosophy plays a key role in sports it brush aside impact on a player either positively or even negatively. Gravity, friction, motion and garden rocket affects sport in every aspect. How physics affects Sports No matter how hard or high you kick a ball as a consequence of gravity it go out be pulled back down to earth. Although the rate at which it descends may vary on its mass and surface area, it will still choose to come down.If thrown at any other angle than 90iit will have a parabolic path (trajectory). Also air resistance and friction will reduce the rate at which the ball moves. The law of conservation of energy also plays a major role in sports. In football game if you kick a ball you are transferring kinetic energy from your foot to the ball. From the pendulum balls by the side you can see how energy transfer works. If you lift the ball at left then energy will be passed on to the neighbouring ball and as a result the ball at the end will move the same distance from which it was released on the other side.Similarly in this diagram the character kicks the ball transferring kinetic energy from his foot to the ball. The ball moves and rises and then the kinetic energy will be converted into gravitational potential energy. Speed is another factor that is based on physics. In any sports victimisation the force applied, snip and the mass you can work out the final/initial velocity assuming that initial/final velocity is zero. Alternatively you can work out speed if you are given the time taken and distance it travels.How technological using has made the data collected more sound and reliable than with traditional methods of studying mechanics. Technology has developed at a staggering rate over the recent years. This allowed us to sum data a good deal more accurately, as humans can make errors in timing due t o reaction time both at start and end. Also the development of light gates allowed us to measure speed, time and acceleration. This can then be plotted on a graph and the graph can gaunt/ edited in real time (as the measurements are taken the graph can be plotted and the line of best fit can be changed).Experiment for measuring Speed You can measure speed using a simple tennis ball. Set a straight horizontal sink in and makes sure it is straight. Measure the length of the track. You will need a timer to time the experiment. Roll the tennis ball through and through the measured distance and time it. Then use V=S/T (Velocity=Displacement/Time) to find out Speed at which it was travelling. Alternatively the velocity can be measure by setting a light gate near the end of the track and connecting it to a Data logger, and this will display the data on the screen, so that it is easier for you to read.You have to set up the data logger so that it measures speed also you have to choose the diameter of the ball which will pass through the light gate.Sources Edexcel AS Physics Ann Fullick, Patrick Fullick, Miles Hudson, Sue Howarth Pearson (2008) page 46 & 47 http//www. soccerballworld. com/Physics. htm Physics World magazine, June 1998 pg 25-27. http//physics-of-sport. net/basketball. html http//www. serioussoccer. net/Documents/PhysicsofSoccer. pdf.
