# Definition of Elastic Collision

An elastic collision is a type of collision in which two objects collide without suffering any permanent deformation or loss of kinetic energy. The kinetic energy of the colliding objects is conserved and redistributed between them in a way that the total kinetic energy of the system remains constant. The colliding objects bounce off each other with the same speed and in opposite directions after the collision.

# Example of Elastic Collision Between Two Billiard Balls

A classic example of an elastic collision is the collision between two billiard balls. When a cue ball hits a stationary ball, it transfers its kinetic energy to the other ball, causing it to move while losing none of its own energy. The two balls then bounce off each other and continue to move in opposite directions with the same speed.

# Elastic Collision Example in Physics

An elastic collision example in physics would be the collision between two subatomic particles. In this type of collision, two particles collide without suffering any permanent deformation or loss of kinetic energy. The kinetic energy of the colliding particles is conserved and redistributed between them in a way that the total kinetic energy of the system remains constant. This type of collision is essential in nuclear physics and particle accelerators.

# Real-life Elastic Collision Examples

Elastic collisions occur frequently in our daily life. For instance, when a baseball player hits a ball with a bat, it results in an elastic collision between the bat and the ball. The kinetic energy of the bat is transferred to the ball, causing it to move with the same speed and direction as the bat. Other examples of elastic collisions include bouncing balls, collisions between cars and collisions between particles in the atmosphere. Elastic collisions are crucial in various fields, including engineering, physics, and sports.
