Abstract
The prescription-strength single most important physical attributes basic reliable in achieving the best achievements in all competitions and sporting events, whether individual or collective ( Vrgih ) , they are the main cause for the change of body movement in both were horizontal or vertical , has agreed a lot of researchers in the Sports , which is characterized by force can achieve the level of performance Mehari best , and crystallize the importance of this force in the performance of most of the skills and the need for it when the performance of each skill and in accordance with the purpose of this performance. That's designed many of the tests that measure most of the manifestations of this force ) Kachtbarat long jump of stability and vertical jump test of fortitude and partridge one man or two men of fortitude ..... Etc. ( All of these tests are based on measuring the horizontal distance covered or the vertical distance of completed units of a meter and its parts , and all of that can not be the distance achieved from these tests reflect real strength , which is paid by the body athlete to accomplish this distance without the involvement of body mass and the time to use this force , since each body its own mass , which is directly proportional to the amount of force exerted to the moment of payment , and this is indicated by the fundamental law of mechanics ( Newton's second law ) which states ) force = mass × acceleration of ) and this stops the level of achievement of the distance the horizontal or vertical where performance Ultra and the amounts of power that can be produced by the athlete in the totals for the major muscles working on the joints involved in this performance. The researcher seeks to clarify the importance of the study of this force through measured artistic and technical gives an indication of the real for the amount of momentum intraday ) explosive ) that his athlete when performing jumping stability will be restricted his research to test the long jump stability to the possibility of demonstrable practical and using a quantitative analysis of the amounts speed and the time of payment and relying on Newton's second law to measure the power at the starting of the cases of fixed and which gives the broader concept of the adoption of the concept of jumping the measured distance in meters , which is affected by many variables and mechanical Kketlh time payment and the speed of the body when starting .
