Choose the option that correctly answers and explains the question, "If the sum of the forces acting on an object equals zero, d
oes this imply the object is at rest?" No, because the sum of the forces equaling zero only implies that the object is not accelerating. No, because even if the sum of the forces equals zero, it may have a nonzero component in one direction. Yes, according to Newton's second law, experiencing zero net force is the definition of being at rest. Yes, because Newton's first law implies that objects in motion must be acted on by a nonzero net force.
No, because the sum of the forces equaling zero only implies that the object is not accelerating.
Explanation:
When the sum of the forces acting on an object equals zero, this implies that the object is at equilibrium. And this could be either static or dynamic equilibrium.
A force is an agent that could change the state or direction of motion of an object. When the sum of all forces acting on an object equals zero, this implies all forces cancels out by resolution. Thus, the state of equilibrum is achieved. So this those not necessarily mean that the object is at rest, but could be in a dynamic equilibrium.
