What is an elastic collision?

Elastic collision occurs when the overall kinetic energy or movement energy of two or more objects after collision is the same as before a collision. Unlike non -non -selastic collision, no energy transforms into another type. In the real world, they usually do not become completely elastic collisions, except subatomical particles, but the collision between two billiard balls is close to approximation.

There are two types of collisions. The first is a non -neelastic collision, which is more common in everyday life. During a non -lastic collision, part of the kinetic energy or movement energy is lost in the impact. This energy is converted into another type of energy such as sound or heat. In the elastic collision, all the kinetic energy of both objects is maintained during the impact.

before two objects are knocked down, each has a certain amount of kinetic energy and momentum. The amount of kinetic energy depends on the weight and speed of each object. As a resuscy Act on Conservation of Energy, which states that energy can never be destroyed,The total energy must be the same as in front of the collision after a collision of two objects. If it is an elastic collision, then all energy remains like kinetic energy and is moved from one object to another.

In fact, there is no collision between large objects never an elastic collision. This is because when large objects intervene, part of the kinetic energy is always lost with different other types of energy, such as sound, heat or object compression. In the microscopic world, such as magnetic interaction of atoms or electrons, there is a chance that the collision is elastic because there is no physical contact between objects. Gravitational interactions between planets are also sometimes classified as a perfectly elastic collision.

The almost elastic collision example in the real world is the interaction between two billiard balls. When a white ball is hit, it gains the certainty of kinetic energy, which then converts during the SRIhs with another ball. If the collision occurs in a straight line, then all kinetic energy is transferred to the target ball, which means that the white ball stops dead and the target ball moves at exactly the same speed. If the balls hit the angle, then the kinetic energy is divided between two.
