A collision is an isolated event in which two or more moving bodies (colliding bodies) exert forces on each other for a relatively short time.

A collision is not constrained to only referring to moving bodies. It can also refer to electronic transactions which share a common resource such as a bus interface. In this case, a collision refers to two simultaneous requests for the shared resource being made.

Although the most common colloquial use of the word "collision" refers to accidents in which two or more objects collide, the scientific use of the word "collision" implies nothing about the magnitude of the forces.

Some examples of physical interactions that scientists would consider collisions:

  • An insect touches its antenna to the leaf of a plant. The antenna is said to collide with leaf.
  • A cat walks delicately through the grass. Each contact that its paws make with the ground is a collision. Each brush of its fur against a blade of grass is a collision.

Some colloquial uses of the word collision are:

  • automobile collision, two cars colliding with each other
  • mid-air collision, two planes colliding with each other
  • ship collision, two ships colliding with each other

Famous quotes containing the word collision:

    I know my fate. One day my name will be tied to the memory of something monstrous—a crisis without equal on earth, the most profound collision of conscience, a decision invoked against everything that had previously been believed, demanded, sanctified. I am no man, I am dynamite!
    Friedrich Nietzsche (1844–1900)

    When the wind carries a cry which is meaningful to human ears, it is simpler to believe the wind shares with us some part of the emotion of Being than that the mysteries of a hurricane’s rising murmur reduce to no more than the random collision of insensate molecules.
    Norman Mailer (b. 1923)
