Physics in Sports Essay

Everything from kicking a orchis into a goal to running from maven fount to the other side of the field is based on physics. physical science plays a key role in sports it ordure impact on a player either positively or even negatively. Gravity, friction, motion and projectile affects sport in every aspect. How physics affects Sports No publication how hard or high you kick a thump as a result of gravity it depart be pulled back raft to earth. Although the arrange at which it descends may vary on its mass and shape up argona, it will still gestate to come down.If thrown at each other angle than 90iit will have a parabolic course (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 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 relieve oneselfs. 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 therefore the kinetic energy will be converted into gravitative potential energy. Speed is another factor that is based on physics. In any sports using the force applied, time and the mass you can work out the final exam/initial velocity assuming that initial/final velocity is zero. alternatively you can work out fixedness if you are given the time taken and distance it travels.How technological development has do the data collected more valid and reliable than with traditional methods of studying mechanics. Technology has developed at a staggering rate everyplace the recent years. This allowed us to measure data much more accurately, as humans can make er rors in timing due to reply time both at start and end. Also the development of crystallise gates allowed us to measure speed, time and acceleration. This can then be plotted on a represent and the graph can bony/ 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 full-strength horizontal track and makes sure it is straight. Measure the length of the track. You will fill a timer to time the experiment. Roll the tennis ball by means of 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 preenting a fire up gate near the end of the track and connecting it to a entropy 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 measur es speed also you have to choose the diameter of the ball which will pass through the light gate.Sources Edexcel AS physical science 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.
