Perfectly Elastic Collision - Real World Examples

In summary, a perfectly elastic collision is a type of collision where the total kinetic energy of the system is conserved, resulting in no loss of energy. Real world examples include collisions between gas molecules, particles in a nuclear reactor, and subatomic particles in a particle accelerator. It differs from an inelastic collision where some kinetic energy is converted to other forms. While difficult to achieve, perfectly elastic collisions are possible if the objects involved are perfectly rigid and there are no external forces. This demonstrates the concept of conservation of energy, where the initial and final total kinetic energy of the system are equal.

What is a perfectly elastic collision?

Does it exist in the real world?

Perfect elastic collision is a collision where no kinetic energy is lost during the collision (so there is no sound and no friction during the collision). This occurs on the atomic level (for example gas particles collide basically elastically)

i thought that's only an elastic collision?
 

FAQ: Perfectly Elastic Collision - Real World Examples

What is a perfectly elastic collision?

A perfectly elastic collision is a type of collision in which the total kinetic energy of the system is conserved. This means that the objects involved in the collision bounce off each other without any loss of energy.

Are there any real world examples of perfectly elastic collisions?

Yes, there are several real world examples of perfectly elastic collisions. Some examples include collisions between gas molecules, collisions between particles in a nuclear reactor, and collisions between subatomic particles in a particle accelerator.

How is a perfectly elastic collision different from an inelastic collision?

In a perfectly elastic collision, the total kinetic energy of the system is conserved, while in an inelastic collision, some of the kinetic energy is converted to other forms of energy, such as heat or sound. This means that inelastic collisions result in a loss of energy, while perfectly elastic collisions do not.

Can a perfectly elastic collision occur in the real world?

While it is difficult to achieve a perfectly elastic collision in the real world, it is possible under certain conditions. In order for a collision to be perfectly elastic, the objects involved must be perfectly rigid and there can be no external forces acting on the system.

What are the implications of a perfectly elastic collision in terms of conservation of energy?

The conservation of energy is a fundamental principle in physics, and perfectly elastic collisions demonstrate this concept in action. In a perfectly elastic collision, the initial total kinetic energy of the system is equal to the final total kinetic energy, showing that energy is neither created nor destroyed, but rather transformed from one form to another.
