an object rests on a horizontal frictionless surface . A horizontal force of magnitude F is applied.This force produces an accleration:
A) only if F is larger than the weight of the object.
B) only while the object suddenly changes from rest to motion.
C) always
D) only if the inertia of the object decreases
Hello!
According to Newton's First Law, F = ma
so force produces acceleration and if the object was placed on a frictionless surface, the force would always produce acceleration irrespective of object's weight.
so, the answer would be option (C).
