Of an elastic collision

Marbles (glass bounces as long as it won't shatter)Curling (http://en.wikipedia.org/wiki/Curling)Basically, an elastic collision is one where neither of the objects loses momentum.http://en.wikipedia.org/wiki/Elastic_collision
Kinetic energy is only conserved if the collision is elastic. All other collisions will have some loss of kinetic energy even when momentum is conserved.
No loss in energy due to collision is for elastic collision. But there will be a loss during collision in case of in-elastic collision. So KE will remain constant before and after collision in case of elastic collision.

There are two kinds of collision - elastic and inelastic. In an elastic collision, all the kinetic energy remains kinetic, though it might be transferred between objects in the collision. So the initially moving object could bounce back with the hit object staying in place, or the hit object might move and the initially moving object might stop. Or it might be a mix of both. Not only things that you think of as elastic have elastic collisions. Very hard things sometimes tend to have elastic collisions too. Not only rubber balls but also billiard balls and baseballs tend to have elastic collisions. The other type of collision is an inelastic collision. Some of the energy can remain in a kinetic form. The rest is converted to heat, sound, and breaking or deformation of the colliding objects.

Elastic collision transfers more energy into motion while inelastic transfers energy into deformation of the objects. Elastic could be called more efficient transfer.
In an elastic collision, no kinetic energy is lost, and the relative speed of separation of the objects after the collision is the same as the relative speed before the collision. In an inelastic collision, part of the elastic energy is lost, and the relative speed after the collision is less.
That's called an "elastic collision".
its a collision
In an elastic collision, all initial kinetic energy is fully restored as final kinetic energy. where nothing is converted into noise, heat or any other form of energy. In an inelastic collision, kinetic energy is "lost" to thermal or sound energy.
The collision is elastic because energy will be conserved. The materials don't react with each other (Velcro does not stick to magnets and magnets do not stick/repel velcro) so its no different than two balls hitting each other. If it was velcro to velcro, and the carts stuck together at the collision, this would be considered an inelastic collision because a lot of Kinetic Energy would be lost. Regardless of the collision, momentum is always conserved.
