Fact Sheet 5 Trajectory and Trajectory Experiments Ronald A. Howard Jr. * Many people think that bullets, The slowing influence is cumulative the bore must be pointed above the shot or arrows travel in straight until the projectile finally comes to line of sight to hit a distant object on lines just like light. It does not take rest. the line of sight. If the sights are much shooting experience to These two factors combined cause above the bore or the arrow, it must realize that projectiles and light projectiles to follow a curved flight cross the line of sight twice, once behave quite differently. The path. If two straight lines are used to while rising and a second time while physics of projectiles (ballistics) is show the line of the bore or the falling toward the earth. The exact discussed at the end of this fact resting position on the string and the shape of the trajectory curve can be sheet for those interested. The main line of sight, the line of flight (path determined by complicated purpose of this material is to help of the projectile) would relate to mathematics or by testing. Actual you understand how trajectory those lines as shown below (Figure testing yields better results for a enters into shooting. 1). given shooter and his or her
