What does mean a perfect elastic collision and a perfect inellastic collision? Do they really exist or it is just by assuming?

then it is conservetive
George Jones said:What about
[tex]F \left( x , y , z \right) = \frac{-y}{x^2 + y^2} \hat{x} + \frac{x}{x^2 + y^2} \hat{y}?[/tex]
A perfect elastic collision is a type of collision where the kinetic energy of the system is conserved. This means that the total kinetic energy before the collision is equal to the total kinetic energy after the collision.
A perfect inelastic collision is a type of collision where the kinetic energy of the system is not conserved. This means that some of the kinetic energy is lost during the collision and is converted into other forms of energy, such as heat or sound.
The elasticity of a collision is affected by the nature of the objects colliding, their masses, and the materials they are made of. The elasticity is also affected by the speed and angle at which the objects collide.
An example of a perfect elastic collision is the collision of two billiard balls on a pool table. The total kinetic energy of the system (the two balls) remains the same before and after the collision.
An example of a perfect inelastic collision is when a car crashes into a wall. The kinetic energy of the car is converted into other forms of energy, such as sound and heat, and the total kinetic energy of the system (the car and the wall) is not conserved.
