The Momentum from each of the objects colliding is added together, and the collision follows a course based on the sum.
Example:
Object A is going 25 (Units) South
Object B is going 20 (Units) North
End Result: 5 Units South
The Energy from each of the objects is transferred to sound, light(sometimes), heat, and mechanical energy.
example if two cars moving they have kinetic energy if they collide some of energy is lost as sound energy which is sound of crash and other part is lost as heat energy which cause the bending of crashed parts.
Momentum is conserved in a collision. If two cars have the same mass and are traveling at the same speed and collide headfirst, the momentum of both cars cancel each other out and they will be motionless. If one has greater speed or mass than the other, it will still have the difference in momentum after the collision.
Total mechanical energy
While energy is ALWAYS conserved, this isn't always useful for calculations, since MECHANICAL ENERGY - the energy that can be easily calculated - is NOT always conserved. On the other hand, momentum is always conserved, whether a collision is elastic or inelastic. (In an elastic collision, energy is also conserved.) Thus, conservation of momentum is often more useful for calculations involving collisions.
Momentum is always conserved in any type of collision. Energy conservation, however, is dependant on elasticity. In a perfectly elastic collision all energy is conserved.
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.

Total mechanical energy
The energy of the momentum in a collision is conserved through the following occurrences; movement of vehicle(s) after impact, deformation of the vehicle(s) or objects hit, heat and sound.
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.

No. Total energy is always conserved, but not so mechanical energy.

no it's not cuz if there is friction energy wont be conserved
no it's not cuz if there is friction energy wont be conserved
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.
it occurs in case of inelastic collision
