What is the difference between elastic and inelastic collisions?
The difference between elastic and inelastic collisions is mainly about what happens to the total kinetic energy during the collision.
In an elastic collision, the total kinetic energy is conserved, meaning no energy is lost — the objects bounce off each other without any lasting deformation or heat.
In contrast, in an inelastic collision, some of the kinetic energy is transformed into other forms of energy like heat, sound, or deformation, so the total kinetic energy after the collision is less than before.
However, the total momentum is always conserved in both types of collisions.

The main difference between elastic and inelastic collisions is what happens to the kinetic energy.
In an elastic collision, the objects bounce off each other and the total kinetic energy stays the same before and after the collision.
But in an inelastic collision, some of the kinetic energy is lost or changed into other forms like heat or sound, so the total kinetic energy decreases.
Even though kinetic energy behaves differently, the total momentum is always conserved in both kinds of collisions.

Elastic collisions are collisions where the objects collide and then separate without losing any kinetic energy — the total kinetic energy stays constant.
In inelastic collisions, the objects may stick together or deform, and some kinetic energy is converted into other forms like heat or sound, so the total kinetic energy after the collision is less than before.
Despite this, momentum is conserved in both elastic and inelastic collisions.

In elastic collisions, the total kinetic energy of the objects involved remains the same before and after they collide, so no energy is lost.
The objects bounce off each other without any permanent change. In inelastic collisions, some of the kinetic energy is converted into other forms like heat, sound, or deformation, so the total kinetic energy decreases after the collision.
But in both types of collisions, the total momentum is always conserved.

The key difference between elastic and inelastic collisions is how kinetic energy behaves. In an elastic collision, the objects collide and bounce apart without losing any kinetic energy — it stays the same before and after the impact. In an inelastic collision, some kinetic energy is lost because it gets converted into other forms like heat, sound, or causes the objects to change shape. However, in both types of collisions, the total momentum of the system remains unchanged.
