Explanation: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.

Conservation Principle

Conservation principle is a fundamental concept in physics that states that a certain physical quantity remains constant during a phenomenon. The conservation principle is based on the idea that energy and matter cannot be created or destroyed but can only be transformed from one form to another.

Physical Quantity

A physical quantity is a measurable property of a physical system. Physical quantity can be mass, energy, momentum, and charge. These quantities can be measured and are often used to describe the behavior of a physical system.

Total Momentum

The conservation of total momentum states that the total momentum of a system remains constant during a phenomenon. The total momentum of a system is the sum of the momentum of all the particles in the system. The conservation of total momentum is a consequence of the law of action and reaction.

Example

An example of the conservation of total momentum is a collision between two objects. During the collision, the momentum of one object is transferred to the other object. However, the total momentum of the system remains constant.

Conclusion

In conclusion, the conservation principle is a fundamental concept in physics that states that a certain physical quantity remains constant during a phenomenon. The conservation of total momentum is an example of a conservation principle that states that the total momentum of a system remains constant.

Conservation Principle:

A conservation principle is a fundamental principle of physics that states that a particular measurable property of an isolated physical system does not change as the system evolves over time. The principle of conservation is based on the fact that the total amount of a particular property in a closed system remains constant over time, even though the system may undergo various transformations.

Example:

The principle of conservation of momentum states that the total momentum of an isolated system of particles remains constant if no external forces act on the system. This means that the total momentum of the system before and after a collision is the same.

Explanation:

Option 'C' is the correct answer because a conservation principle states that a physical quantity, such as momentum, energy, or mass, does not change in a phenomenon. The quantity has the same value before and after the phenomenon because of the conservation principle. This means that the total amount of the physical quantity is conserved, and no new quantity is created or destroyed during the phenomenon.

For example, in the case of conservation of momentum, the total momentum of a system of particles before and after a collision is the same. This means that the sum of the momenta of all the particles in the system does not change, even though some of the particles may change direction or speed during the collision. The conservation of momentum is a fundamental principle of physics and is used to explain many phenomena, including collisions between particles, the behavior of rockets, and the motion of planets in orbit.

Conclusion:

In conclusion, the conservation principle is a fundamental principle of physics that states that a particular measurable property of an isolated physical system does not change as the system evolves over time. The principle of conservation is based on the fact that the total amount of a particular property in a closed system remains constant over time, even though the system may undergo various transformations. The correct answer to the question is option 'C' because a conservation principle states that a physical quantity does not change in a phenomenon.
