Impact (mechanics)
In mechanics, an impact is when two bodies Collision, collide. During this collision, both bodies decelerate. The deceleration causes a high force or Shock (mechanics), shock, applied over a short time period. A high force, over a short duration, usually causes more damage to both bodies than a lower force applied over a proportionally longer duration. At normal speeds, during a perfectly inelastic collision, an object struck by a projectile will Deformation (engineering), deform, and this deformation will absorb most or all of the force of the collision. Viewed from a conservation of energy perspective, the kinetic energy of the projectile is changed into heat and sound energy, as a result of the deformations and vibrations induced in the struck object. However, these deformations and vibrations cannot occur instantaneously. A high-velocity collision (an impact) does not provide sufficient time for these deformations and vibrations to occur. Thus, the struck material behaves ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
