In an elastic collision, kinetic energy is conserved and momentum is conserved. Both objects bounce off each other after the collision. In an inelastic collision, kinetic energy is not conserved, but momentum is conserved. The objects stick together or deform after the collision.
Background
Momentum of an of object is the product of its mass and velocity.
A collision is when two or more objects hit each other.
During a collision, the total momentum of a closed system is conserved;however, the kinetic energy may or may not be conserved during a collision.
Answer
An elastic collision is a collision in which the total kinetic energy of a system is conserved; that is, the sum of the kinetic energies of the colliding objects before and after the collision is the same.
The collision of pool balls is considered an elastic collision because the amount of kinetic energy lost is trivial.
In an inelastic collision on the other hand , kinetic energy is not conserved. Most collisions are inelastic because kinetic energy is transformed into other forms of energy (such as thermal energy, potential energy, sound, etc.) during the collision process.
An example of an inelastic collision is a car crash.
Elastic collison => Momentum and kinetic energy of colliding bodies are conserved.
Colliding bodies should be perfectly elastic and they regain their previous configuration after collison is over.
InElastic collison => Momentum is conserved but kinetic energy of colliding bodies are not conserved. Colliding bodies are not perfectly elastic. Their shape and size(configuration) changes after the collison.
That's a collision in which mechanical energy gets lost. The colliding objects stick together; or if they rebound, they rebound with less speed (of one object relative to the other object) than they had before the collision.
If a ball bounces to the same height as it was released, it is an elastic collision because all the energy of the crash is preserved. If you hear the bounce, it is not an elastic collision because some of the energy has been convered to sound.
An elastic collision is a collision in which the total kinetic energy of a system is conserved.
Elastic collision transfers more energy into motion while inelastic transfers energy into deformation of the objects. Elastic could be called more efficient transfer.

What is collision?
A collision is an isolated event in which two or more moving bodies (colliding bodies) exert forces on each other for a relatively short time.Although the most common colloquial use of the word "collision" refers to accidents in which two or more objects collide, the scientific use of the word "collision" implies nothing about the magnitude of the forces.Types of collisionsA perfectly elastic collision is defined as one in which there is no loss of kinetic energy in the collision. In reality, any macroscopic collision between objects will convert some kinetic energy to internal energy and other forms of energy, so no large scale impacts are perfectly elastic. However, some problems are sufficiently close to perfectly elastic that they can be approximated as such. An inelastic collision is one in which part of the kinetic energy is changed to some other form of energy in the collision. Momentum is conserved in inelastic collisions (as it is for elastic collisions), but one cannot track the kinetic energy through the collision since some of it is converted to other forms of energy.Collisions in ideal gases approach perfectly elastic collisions, as do scattering interactions of sub-atomic particles which are deflected by the electromagnetic force. Some large-scale interactions like the slingshot type gravitational interactions between satellites and planets are perfectly elastic.Collisions between hard spheres may be nearly elastic, so it is useful to calculate the limiting case of an elastic collision. The assumption of conservation of momentum as well as the conservation of kinetic energy makes possible the calculation of the final velocities in two-body collisions.
Is momentum conserved in a perfectly inelastic collision?
In any physical process, momentum will always be conserved. Momentum is given by p = m*v. There is also something called law of conservation of momentum.
Which of these is included as a postulate in the kinetic-molecular theory of an ideal gas?
collision between molcules are elastic
Does hooke's law apply to elastic materials or to inelastic materials?
Hooke's law applies to elastic materials, which means that the material will return to its original shape when the deforming force is removed. Inelastic materials do not follow Hooke's law as they do not exhibit linear elasticity.
Do gas particles bounce?
Atoms and molecules bounce during collisions of any kind when they are in a solid, liquid or gas. The word "bounce" when used to refer to atoms or molecules means that the have a collision that may be considered elastic. This word "bounce" is not especially scientific. Instead one typically hears about colliions and those collisions are termed elastic or inelastic. If two chemical species are involved in a chemical reaction, then when they have a reactive collision, they do not bounce, but they exit the collision changed in some way. They exchange atoms or somehow exit the collision as one or two or more chemical species. Such collisions do not conserve kinetic energy.
Elastic and inelastic collisions?
its a collision
How do you determine if a collision was elastic inelastic or perfectly inelastic?
just check momentum before and after and if they're the same then elastic if not then inelastic.
What is the difference in elastic collision and inelastic collision?
Elastic collision transfers more energy into motion while inelastic transfers energy into deformation of the objects. Elastic could be called more efficient transfer.
What is elastic and inelastic collisions in terms of momentum?
In elastic collisions, both momentum and kinetic energy are conserved. This means that momentum before and after the collision is the same, and the objects bounce off each other without any loss of kinetic energy. In inelastic collisions, momentum is conserved but kinetic energy is not. Some kinetic energy is converted into other forms of energy, such as heat or sound, during the collision.
What is elastic and inelastic collision?
In an elastic collision, both kinetic energy and momentum are conserved. This means that there is no net loss of energy during the collision. In an inelastic collision, kinetic energy is not conserved, and some of the energy is transformed into other forms such as heat or sound.

What happens to the vehicles in a collision and the principles of elastic and inelastic collisions?
In a collision, vehicles experience a transfer of momentum and kinetic energy. In an elastic collision, kinetic energy is conserved, and the vehicles rebound off each other. In an inelastic collision, kinetic energy is not conserved, and the vehicles remain stuck together after the impact.
What will be the total higher quantity do in the elastic inelastic and unit-elastic?
The midpoint between elastic and inelastic is unit elastic
Distinguish beween and elastic and inelastic collision for wich type of collision is momentum conserved?
Momentum is conserved in both elastic and inelastic collisions. Mechanical energy is conserved only in elastic collisions. In inelastic collisions, part of the energy is "lost" - usually most of it would be converted to heat, eventually.
Is the collision between the ball and the pendulum elastic or unelastic?
The collision between the ball and the pendulum is typically an inelastic collision, where kinetic energy is not conserved because some of it is transformed into other forms of energy, such as sound or thermal energy. In an elastic collision, kinetic energy is conserved, which is not the case in this scenario.
Velcro cart to magnestic bumper cart collision is this an inelastic or elastic collision?
elastoc collision because they can stick together
What is the difference between elastic and in elastic collisions?
Elastic collision transfers more energy into motion while inelastic transfers energy into deformation of the objects. Elastic could be called more efficient transfer.
