Bullets are not easy to stop because they travel at such high velocities. When a bullet is projected from a firearm, it possesses energy due to its mass and motion. This is referred to as kinetic energy. In order to stop it, the kinetic energy needs to be absorbed and transferred from the bullet into something else. This is where bullet traps come in.nnWhen a bullet hits the bullet trap, the specific design and materials of the bullet trap are made to absorb the kinetic energy of the bullet. In the case of steel bullet traps, the steel plates are angled very precisely to achieve a deflection into a bullet trap rather than penetration or ricochets. The bullet is stopped by transferring its kinetic energy to the materials in the bullet trap.
