Document Summary
Opo"s in projecting: maximum horizontal distance (decreased angle = open kinetic link, maximum vertical distance (increased angle = closed kinetic link) Horizontal and vertical distance are affected by the angle of projection and more importantly the velocity of the projectile at release: maximum accuracy, maximum accuracy with speed. Ex: by flexing your wrists in a golf swing, you decrease r, increasing angular acceleration. You then increase your r before contact, increasing linear velocity. An angle of projection of only 45 degrees is beneficial for when the release height of. The angle of projection for a golf ball is less than 45, but the angle of the golf club puts. The resultant vector angle is less than 45 degrees (ex: long jump / long throw) A resultant angle of 20 degrees has a horizontal velocity 3x greater than vertical velocity. The resultant vector angle is greater than 45 degrees (ex: volley ball jump / high jump)
