Question

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

Answer 1

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).
