| | Effects of Stone Projectile Points |
 | | Prehistorically, the concept of making smaller projectiles travel faster can be generally traced in the study of stone projectile points, with heavier points generally occurring earlier and lighter points occurring more recently in the archaeological record. |
 | | In testing the mass of the points on a digital scale, allthree projectile points were found to weigh essentially the same at 7.6, 7.7, and 7.8 grams, respectively. |
 | | Projectile points made from other materials can be made to have the same mass as a stone point, but they would be larger, less efficient and, therefore, less desirable than stone. |
