An impact.
The point of impact or cataclysmic event.
The impact of the meteorite caused a huge crater in the ground.
the term is impact
When you hit the ground. While they are falling they are in the air, and falling in and of itself will not kill you. The impact will always kill you -- unless you have a heart attack during the fall.
The impact force depends upon the height from which it has fallen (IE- its velocity upon impact), and the duration of impact (determined by the elasticity of the collision). However, the object exerts no force upon the ground *while* falling.
a ball only when it hits the ground though.
An impact crater is a crater, meaning a depression in the ground, which results from an impact, meaning a violent collision of some object with the ground at that location. Generally, such collisions are the result of meteor impacts or other impacts of one object in space on another. Many more impact craters are visible on the moon than on Earth, because on Earth such craters are eventually eroded away by weather and other erosive forces, whereas they tend to be undisturbed on the moon.
Medical waste can impact the environment in many ways. It can have an even worse impact if it is improperly disposed of. One effect medical waste has on the environment is contaminating ground water and food sources.
The direction of lightning can impact its impact on the surrounding environment by influencing where the energy is discharged. When lightning strikes the ground directly, it can cause more damage to the immediate area, such as starting fires or damaging structures. If lightning strikes nearby but not directly on the ground, the impact may be less severe.
