![]() ![]() In the case of gunshot projectiles this means that it is still dangerous.Ī hard projectile striking a rigid surface at a steep angle will transfer most of its energy into the surface. To summarise the abstract a ricochet occurs when a projectile strikes a surface (either solid or liquid) at such a shallow angle that the projectile transfers only a small part of its energy to the surface and so continues on at a speed close to its speed before the contact. If you want a fuller discussion of the physics of bullet and shotgun pellet ricochets look at the Abstract section of this report in the library of the US National Criminal Justice Reverence Service. 'Glancing' in that sense means that the "angle of incidence" is very shallow, typically less than 30 degrees to the surface off which the projectile ricochets. The word 'glancing' is the key difference between the definitions of 'bounce' and ricochet. ![]()
