Note: If the object hit your eye at a high speed or is a piece of metal, do not try to remove it.

Did an object hit the eye at high speed?

Only when the object hit the floor could they get up and run.

The object hit the landing and rolled to a stop against his left foot.

Collision detection is a program used on computers to help it understand when two objects will hit into each other.

A moment later, I heard an object hit the sidewalk - his eyeglasses.

An object flew in, hit the wall, and landed on the floor.

Had this object hit Earth, it would probably have detonated high in the atmosphere.

Perhaps, some experts suggested, two or more celestial objects hit the Earth simultaneously.

But as the solar system has aged, fewer objects have hit Earth.
