Define law of conservation?
In
physics https://en.wikipedia.org/wiki/Physics |  |
, a
conservation law states that a particular measurable property of an isolated
physical system https://en.wikipedia.org/wiki/Physical_system | |
does not change as the system evolves over time. Exact conservation laws include
conservation of energy https://en.wikipedia.org/wiki/Conservation_of_energy | |
,
conservation of linear momentum https://en.wikipedia.org/wiki/Conservation_of_linear_momentum | |
,
conservation of angular momentum https://en.wikipedia.org/wiki/Conservation_of_angular_momentum | |
, and
conservation of electric charge https://en.wikipedia.org/wiki/Conservation_of_electric_charge | |
. There are also many approximate conservation laws, which apply to such quantities as
mass https://en.wikipedia.org/wiki/Conservation_of_mass | |
,
parity https://en.wikipedia.org/wiki/Parity_(physics) | |
,
lepton number https://en.wikipedia.org/wiki/Lepton_number | |
,
baryon number https://en.wikipedia.org/wiki/Baryon_number | |
,
strangeness https://en.wikipedia.org/wiki/Strangeness | |
,
hypercharge https://en.wikipedia.org/wiki/Hypercharge | |
, etc. These quantities are conserved in certain classes of physics processes, but not in all.

Define law of conservation?
The sum of momenta of the two objects before collision is equal to the sum of momenta after collision provided there is no external unbalanced force acting on them. This is known as the law of conservation of momentum. ORAn isolated system (where there is no external force), the total momentum remains conserved.
