According to the law of conservation of momentum,a)the momentum of an ...
The law of conservation of momentum states that the total momentum of an isolated system of interacting particles is conserved. Let's break down this concept and understand why option 'C' is the correct answer.
What is momentum?
Momentum is a fundamental concept in physics that describes the motion of an object. It is defined as the product of an object's mass and its velocity. Mathematically, momentum (p) can be calculated as p = m * v, where m is the mass of the object and v is its velocity.
Conservation of momentum
According to Newton's third law of motion, for every action, there is an equal and opposite reaction. This means that when two objects interact, the forces they exert on each other are equal in magnitude and opposite in direction. As a result, the total momentum of the system remains constant.
Isolated system
An isolated system refers to a system in which no external forces are acting on it. In other words, there are no external influences that can change the momentum of the system. This could be a closed box or a system in which the external forces are negligible.
Interacting particles
Interacting particles are objects that exert forces on each other. When these particles collide or interact in any way, they exchange momentum. The law of conservation of momentum states that the total momentum of the system remains constant before and after the interaction, as long as no external forces are involved.
Option 'C'
Now, let's relate these concepts to the given options. Option 'C' states that the total momentum of an isolated system of interacting particles is conserved. This is correct because an isolated system ensures that there are no external forces, and interacting particles exchange momentum without any external influence. Hence, the total momentum of the system remains constant.
Options 'A' and 'B' are incorrect because they do not mention the requirement of an isolated system. In option 'A', the conservation of momentum is limited to an isolated system, not any system. Option 'B' introduces the concept of fields, which are not necessary for the conservation of momentum in an isolated system of particles.
Option 'D' is incorrect because it states that the momentum of an interacting system of particles and fields is conserved, which is not always true. The conservation of momentum depends on the presence of external forces and the isolation of the system, rather than the involvement of fields.
In conclusion, the correct answer is option 'C' because the law of conservation of momentum specifically applies to an isolated system of interacting particles.
