# Difference between elastic collision and inelastic collision

The collision can be classified as either elastic or non-elastic. The main difference between elastic and inelastic collisions is that inelastic collisions, the total kinetic energy of the colliding objects before the collision is equal to their total kinetic energy after the collision. In inelastic collisions, the total kinetic energy of the objects after the collision is less than the total kinetic energy of the objects before the collision. The main difference between elastic collision and inelastic collision is that elastic collision is a type of collision in which the kinetic energy remains the same before and after the collision, while the inelastic collision is a type of collision in which the kinetic energy does not stay the same. before and after the collision.

## Key differences

• An elastic collision denotes the type of collision in which the kinetic energy remains the same throughout the collision, while the inelastic collision denotes the type of collision in which the kinetic energy does not remain the same or is conserved throughout the collision.
• In an elastic collision, energy is never wasted, whereas in an inelastic collision, energy is always wasted.
• An elastic collision is a process in which heat does not build up on the other side; inelastic collision is a process in which heat is produced.
• An elastic collision is a type of collision in which the body returns after the collision without any twist or shift; on the other hand, inelastic collision is a type of collision in which the body returns after the collision with the change of shape or turn.
• An elastic collision always occurs in gas molecules and air molecules, while inelastic collision always occurs in liquids and solids.
• In an elastic collision, the forces during the collision do not need to be changed in other ways and remain the same, whereas, in an inelastic collision, the forces during the collision change to other ways and do not remain the same.
• An elastic collision is only justified for subatomic particles, while an inelastic collision is only justified for macro objects.

## Elastic vs. inelastic collision – Overview

An elastic collision refers to the type of collision in which the kinetic energy remains the same throughout the collision, while an inelastic collision refers to the type of collision in which the kinetic energy does not remain the same or is not conserved throughout the collision. . An elastic collision is a process in which heat is not produced on the other side; An inelastic collision is a process in which heat is produced.

An elastic collision is a type of collision in which the body returns after the collision without any twist or shift; on the other hand, inelastic collision is a type of collision in which the body returns after the collision with the change of shape or turn. In an elastic collision, energy is never wasted, whereas in an inelastic collision, energy is always wasted.

In an elastic collision, the forces during the collision do not change to other forms and remain the same, whereas, in an inelastic collision, the forces during the collision change to other forms and do not remain the same. An elastic collision always occurs in gas molecules and air molecules, while inelastic collision always occurs in liquids and solids. An elastic collision is only justified for subatomic particles, while an inelastic collision is only justified for macro objects.

In general, a collision is defined as an encounter or interaction of particles or objects that causes an exchange of energy and / or momentum. It is easier to examine collisions closely in terms of momentum if we consider an isolated system, such as a system of particles (or balls) engaging head-on collisions. For simplicity, we will only consider crashes in one dimension.

In an elastic collision, total kinetic energy is conserved. That is, the total kinetic energy of all objects in the system after the collision is equal to their total kinetic energy before the collision. Kinetic energy could be exchanged between objects in the system; but the total kinetic energy of the system will remain constant. Therefore,

## What is an elastic collision?

An elastic collision is a process in which the forms of energy remain the same throughout the process. It is the type of collision in which the kinetic energy remains the same during the rebound of a body. It is the process in which the law of conservation of energy and the law of conservation of moment are valid. The momentum throughout the collision remains the same.

It is the process in heat. It does not occur. In an elastic collision, the change in shape and size does not occur. The bodywork does not show any deformation during the entire collision process. In an elastic collision, the forms of energy are not wasted. Elastic collision always occurs in gas molecules and also in air molecules. In this type of collision, the forces acting on the body are not converted into other forms of energy.

It is only justifiable for microparticles. The perfectly elastic collision does not occur in our daily life. Because in each process, a small amount of energy is always lost from the system and converted into other forms of energy. We can also call this collision an ideal collision.

During the elastic collision process, kinetics are not converted to other forms of energy, such as sound energy, thermal energy, light energy, etc. and does not change to other changing shapes of the solids. It is the process of exchanging the different properties of matter. Examples are the bouncing of a rubber ball on the marble floor and the bouncing of rubber on the smooth surface, etc.

An elastic collision is a collision where the total kinetic energy of the bodies before the collision is equal to their total kinetic energy after the collision. This type of collision is impossible to observe in the macroscopic world, since at least a small amount of kinetic energy is lost during collisions. Note that if the collision occurs in a closed system, full momentum is conserved. The total energy is also conserved, however some of the kinetic energy has been transformed into other forms.

A collision between two billiard balls is, to a good approximation, elastic. Elastic collisions are more plausible for collisions between fundamental particles. However, even in these interactions, part of the kinetic energy can be lost in the form of radiation.

## What is an inelastic collision?

An inelastic collision is a process in which the other forms of energy do not remain the same throughout the process. It is the process in which the kinetic energy does not remain the same during the rebound of a body. It is the process in which the law of conservation of momentum of a system is preserved before and after the collision. But the law of conservation of energy of a system does not remain the same before and after the collision.

It is the process in which heat is produced. In an inelastic collision, the shape and size of the body change. The body shows some deformation during the whole process. In an inelastic collision, energy is wasted throughout the entire process. In inelastic collisions, liquids and solids are produced. In this type of collision, the forces acting on the body are converted into other forms of energy.

It is only justifiable for macro objects. In our daily life, all kinds of collisions are usually inelastic collisions. When we drop the object to the ground, the kinetic energy of the object is converted into sound energy, thermal energy, and energy from the motion of the breaking particles. Examples are the bounce of a plastic ball on the rough surface and the bounce of a plastic ball on the hard surface, etc.

An inelastic collision is a collision in which the total kinetic energy of the colliding particles before the collision is greater than the total kinetic energy of the particles after the collision. During impact, kinetic energy is converted into other forms, such as heat or energy used to cause deformations in colliding bodies. A collision is said to be perfectly inelastic if the colliding bodies stick together and move together after the collision.

## Conclution

The above discussion concludes that elastic collision and inelastic collision are types of collision. An elastic collision is a type of collision in which there is no net change in kinetic energy during the entire process, while an inelastic collision is a type of collision in which there is a net loss of kinetic energy during the entire process.
