Both conservation laws are applied. The conservation of momentum and conservation of energy. However, in an inelastic collision, kinetic energy is not conserved. But total energy IS CONSERVED and the principle of conservation of energy does hold.
Everywhere.
If the two bodies form a closed and isolated system (that is no other external forces act on the system apart from the forces that the bodies exert on each other and no mass is allowed to enter or leave the system), the principle of conservation of momentum SHOULD be used. Remember: As long as the condition in the brackets above hold, the principle of conservation of momentum holds. Next, depending on the nature of the collision, another conservation law can be used. If the collision is perfectly elastic, then kinetic energy is conserved. Note that although kinetic energy is not always conserved, TOTAL energy is ALWAYS conserved. You could still apply the principle of conservation of energy for an inelastic collision provided you knew the amount of energy converted to other forms of energy.
Hi, in line with Newton's laws of motion the momentum before and after a collision is always conserved (when no external force is applied to change the systems momentum). In elastic collisions we can apply the conservation of momentum and conservation of energy principles. In inelastic collisions we can only apply the conservation of momentum principle. Energy is not conserved in inelastic collisions because energy is lost through small deformations, noise, friction, etc. We can compute the coefficient of restitution that helps determine this degree of energy loss from impulse-momentum equations.

Generator general principle mechanical energy converted in to electrical energy.
In general Conservation of Energy does not hold internal to a system, it only holds at the boundary of the system. This is where the limits of the system are. Internal to the system energy is not conserved. The situations where the Conservation does not apply is where the force is not zero or the first derivative of energy is not zero.

conservation laws do apply to stars, as mass/energy is conserved by the formula E(energy) = M(mass) x C squared (speed of light), this happens as a nuclear fusion reaction when the hydrogen molecules in the stars and fused to make Helium, some mass is lost (converted to energy). cheers
There are several laws of conservation; please clarify which one you mean. For example, there is the law of conservation of mass, of energy, of momentum, of rotational momentum, of electrical charge, and others.
All of the energy the sun provides to Earth was previously contained within the atoms of the sun.
conservation of momentum depend upon mass and velocity.by the formula its given as m'.v'=m.v but the energy have void area it apply in themodynamics,revolution of planet in every physical universe..where is velocity is not taken in count there no momentum but there have some specific energy of body
