In a collision what is conserved?
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.
Is the mechanical energy always conserved?
IF you use d'alemberts pinciple and it is aparantly, according to physics conserved in collisions, be they either elastic or non-elastic collisions
Does momentum conserved during collisions?
Energy, if collision is rigid, total momentum is a constant also.
Need an explanation why kinetic energy is always conserved during elastic collision what is meant by conserved?
In this context "conserved" means the total kinetic energy of all the objects is the same after the collision as before the collision. Note, the TOTAL is the same but the individual kinetic energies of each object may be different before and after. When two or more objects are about to collide they have a certain total kinetic energy. It is common that during the collision some of the kinetic energy is transformed into heat. So after the collision the total kinetic energy is less then before the collision. This is a non-elastic collision. There are some collisions, however, in which none of the kinetic energy is changed to heat. These are called ELASTIC collisions. So the total kinetic energy doesn't change, or is "conserved". There is another possible non-elastic collision. If during the collision there is an explosion, then its possible for the objects to have a larger total kinetic energy after the collision as they aquire some of the explosive energy. Finally note, that in all collisions the TOTAL vector momentum is the same just before and just after the collision. So in a collision momentum is always conserved.
A collision in which the total momentum and kinetic energy remain constant?
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.

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.
During the interval of collision is the momentum conserved?
well i know momentum remains same before and after collision... But what about the period during which collision takes place?

Is neutron number conserved in radioactive decay?
The number of neutrons is not conserved during decay.

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.
Why is mass conserved during the combution of methane?
Its conserved during the combustion of anything - the mass of the products is always equal to the mass of the materials that react.
Why does the ball not bounce as high when its first dropped?
The answer lies in co-efficient of restitution. (COR) COR is the ratio of speeds before and after impact. Normally, it is expected that the ball should reflect off the surface with the same speed with which it strikes. However, this happens only in the case of elastic collisions. Elastic collisions are ideal collisions in which both momentum and kinetic energy are conserved. COR=1. In this case, the ball bounces as high as the height from where it was thrown. In reality however, collisions are inelastic. COR<1. K.E is not conserved. Energy is lost in other forms like heat as a result of which the ball doesn't bounce as high.
How is mass conserved during the process of photosynthesis?
It Doesn't
