Write About Conservation laws
Answers
In physics, a conservation law states that a particular measurable property of an isolated physical system does not change as the system evolves over time. Exact conservation laws include conservation of energy, conservation of linear momentum, conservation of angular momentum, and conservation of electric charge.

Answer:
All conservation laws such as conservation of momentum, energy, angular momentum, charge etc. are considered to be fundamental laws in physics. These are based on observations and experiments. It can be verified, or disproved, by experiments. An experiment whose result is in conformity with the law verifies or substantiate the law; it does not prove the law. On the other hand, a single experiment whose result goes against the law is enough to disprove it.
The law of conservation of momentum has been deduced from large number of observations and experiments. This law was formulated nearly three centuries ago. It is interesting to note a single situation has been realised so far. which contradicts this law. Several experiences of every-day life can be explained on the basis of the law of conservation of momentum.
