Collision - online puzzles

A collision is the event in which two or more bodies exert forces on each other in about a relatively short time. Although the most common use of the word collision refers to incidents in which two or more objects collide with great force, the scientific use of the term implies nothing about the magnitude of the force.

Some examples of physical interactions that scientists would consider collisions are the following:

When an insect lands on a plant 's leaf, its legs are said to collide with the leaf.

When a cat strides across a lawn, each contact that its paws make with the ground is considered a collision, as well as each brush of its fur against a blade of grass.

When a boxer throws a punch, his fist is said to collide with the opponent's body.

When an astronomical object merges with a black hole, they are considered to collide.Some colloquial uses of the word collision are the following:

A traffic collision involves at least one automobile.

A mid- air collision occurs between airplanes.

A ship collision accurately involves at least two moving maritime vessels hitting each other, or the related term, collision, when a moving ship strikes a stationary ship.

Overview

Collision is short-duration interaction between two bodies or more than two bodies simultaneously causing change in motion of bodies involved due to internal forces acted between them during this. Collisions involve forces (there is a change in velocity).
