Explanation:
in physics
a collision is any event in which two or more bodies exert forces on each other in a relatively short time.
in chemistry
Collision theory, theory used to predict the rates of chemical reactions, particularly for gases. The collision theory is based on the assumption that for a reaction to occur it is necessary for the reacting species (atoms or molecules) to come together or collide with one another.
Collisions are of three types:
perfectly elastic collision.
inelastic collision.
perfectly inelastic collision.
Rear-end collisions
Rear-end collisions are the most common type of accident, accounting for approximately 29% of all crashes. These collisions are the result of one vehicle colliding into the back end of another. These accidents can occur during heavy traffic and may end up involving several cars.
The collisional cross section is defined as the area around a particle in which the center of another particle must be in order for a collision to occur. In the image below, the area within the black circle is molecule A's collisional cross section.
