Vedclass · Answer

(B) According to Newton's First Law of Motion,a body remains at rest or continues to move with a constant velocity unless acted upon by an external unbalanced force.When a body is at rest,the net force acting on it is zero.When a body moves with a constant velocity,its acceleration is zero,which implies that the net force acting on it is also zero.Therefore,both states are physically equivalent in the context of dynamics because in both cases,the resultant (net) force acting on the body is zero $(F_{net} = 0)$.This condition is known as translational equilibrium. The property of a body to resist any change in its state of rest or uniform motion is called inertia,which is measured by the mass of the body.

Why are the states of a body at rest and a body moving with constant velocity considered equivalent in terms of net force?
