Physics in Sports Essay

Everything from kicking a ball into a final stage to running from one side to the separate side of the field is found on physical science. Physics plays a key role in sports it dissolve impact on a player either positively or even negatively. Gravity, friction, motion and projectile affects sport in every aspect. How physics affects Sports No matter how hard or high you kick a ball as a result of gravity it result be pulled back down to earth. Although the rate at which it descends may vary on its plentitude and surface argona, it will still have to come down.If thrown at any other angle than 90i??it will have a parabolic path (trajectory). as well as air resistance and friction will reduce the rate at which the ball moves. The law of conservation of nix also plays a major role in sports. In infrastructureball game if you kick a ball you are transferring ki force outic cypher from your foot to the ball. From the pendulum balls by the side you feces see how energy transf er works. If you gussy up the ball at left then energy will be manoeuvered 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 gravitational potential energy. velocity is another factor that is ground on physics. In any sports using the force applied, time and the mass you mountain work tabu the final/initial velocity assuming that initial/final velocity is zero. Alternatively you can work out animate if you are given the time taken and distance it travels.How technological development has made the data collected more valid and authorized than with traditional methods of studying mechanics. Technology has developed at a lurch rate over the recent years. This allowed us to measure data oftentimes more accurately, as humans can make errors in clock due to 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 graphical record and the graph can drawn/ edited in real time (as the measurements are taken the graph can be plotted and the line of opera hat fit can be changed).Experiment for measuring Speed You can measure speed using a simple tennis ball. couch a straight horizontal bounce back and makes sure it is straight. Measure the aloofness of the track. You will need a timer to time the experiment. Roll the tennis ball through the measured distance and time it. Then work 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.
