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.

In an elastic collision, kinetic energy is conserved, and the objects bounce off each other without any loss of energy. In an inelastic collision, kinetic energy is not conserved, and some of the energy is transformed into other forms, such as heat or sound, during the collision.

Because in physics the definition of an elastic collision is one in which the total kinetic energy (of the bodies involved) is the same after the collision as it was before hand.

In the case of a rubber ball hitting a wall some of that kinetic energy is lost due the ball deforming on impact (which manifests as heat - although not in quantities that are easily noticeable).

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 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.

### 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 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?

When the collision is perfectly elastic then energy is not lost but exchanged between the bodies collided. So total KE would remain the same before and after collision. But in case of inelastic collision, there would be loss of energy in the form of heat or sound or vibration etc etc. But whether collision is elastic or inelastic the momentum is conserved. That is, the total momentum in a given direction would be the same before and after collision.

### What is the difference between elastic and inelastic collisions?

Elastic Collision is the collision in which colliding objects rebound without lasting deformation or heat generation.Inelastic collision is a collision in which the colliding objects become distorted and generate heat during collision and possibly stick together.

### 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.
