Answer 2

Answer:

The correct answer is (d) none of above.

Explanation:

• All of the given options are examples of law of conservation of momentum.

• If there are no external forces acting on the system, the momentum of the system is constant.

• In order to solve collision-related problems, it is essential to understand the conservation of momentum, which holds true across all branches of physics.

• When applying the conservation of momentum concept, care must be taken to ensure that the system under investigation is truly free from outside influences.

• The second and third principles of Newton immediately imply the momentum conservation principle.

• The fundamental physical rule stating that, in the absence of external forces acting on the system, a system's momentum will remain constant.
• All areas of physics are covered by the universally applicable principle of momentum conservation.
• In particular, momentum is preserved even when a system's particles interact with one another or when all mechanical energy is not kept constant.
• The second and third principles of Newton immediately imply the momentum conservation principle.
• The theory can be applied to systems with any number of particles, even though it will only be demonstrated here for the straight-line motion of a two-particle system.
• A mass that is a particle has minimal rotational effects due to its tiny size.
• Since rigid bodies can be thought of as assemblies of many particles, momentum will also be preserved for rigid structures that are large enough that rotation must be taken into account.
