A kinetic energy weapon is a type of directed-energy weapon that uses the kinetic energy of a projectile to damage its target. Kinetic energy weapons typically use projectiles, such as bullets, missiles, or bombs, to deliver their kinetic energy to the target. The kinetic energy of the projectile is transferred to the target upon impact, causing damage due to the transfer of momentum. Kinetic energy weapons are often used in military applications, such as anti-tank weapons and air-to-air missiles.
