THE WEIGHT OF PROJECTILE AND THROW DISTANCE

Abstract

The throw distance depends on initial speed, elevation angle, weight of projectile and its aerodynamic properties. In terms of biomechanics, the initial speed is dependant on the weight of projectile, force capacity of the subject and the throwing technique. When addressing motion equation of oblique throw inclusive of air resistance and projectile weight we get an equation expressing maximal throwing distance Xm (Packel & Yuen, 2004; De Mestre, 1990): Xm = (v0)^2*sin(2*alpha)/g * (1 - 2 * sqrt(2) * k*v0^3/3*m*g^2) The aim of the study is to analyze the influence of projectile weight on throw distance under stabilized aerodynamic parameters.
