Kinetic energy is the energy possessed by an object due to its motion, calculated using the formula KE = 1/2 mv², where m is the mass and v is the velocity of the object. When a projectile impacts a target, the kinetic energy is directly proportional to both its mass and the square of its velocity. Because of this relationship, a high-speed impact or a massive object can impart a significant amount of energy upon collision, leading to damage.

For example, when an aircraft strikes a target, the combination of its considerable mass and high speed can result in a substantial transfer of kinetic energy, leading to structural failures, penetration, or even explosive effects. This is why projectiles and missiles designed to cause destruction harness the concepts of kinetic energy effectively, leading to significant damage to structures, vehicles, or other targets.

Other potential influences on damage, such as sound waves, thermal energy, and chemical reactions, do not primarily involve kinetic energy in the same direct manner as mass and speed do in impacting an object. Sound waves can create pressure changes or cause hearing damage but do not impart physical damage through kinetic energy in the same way as a projectile. Thermal energy refers to heat generated either through friction or combustion, rather than direct physical impact.
