Correct option is B
According to
Newton’s Second Law of Motion, the rate of change of momentum of an object is directly proportional to the resultant force applied. Mathematically,
Here, F is the force, mmm is the mass, and v is the velocity. This explains why an object accelerates when a force is applied.
Important Points:
· Momentum = Mass × Velocity (p = mv).
· Newton's second law is the basis for calculating force in dynamic systems.
· If force increases, the rate of change of momentum increases proportionally.
· Force is measured in newtons (N).
· The law applies to systems with constant or variable mass.
