NEWTON'S LAWWhich of the following best describes Newton's First Law of Motion?B) Objects at rest will stay at rest unless acted upon by a force.Newton's First Law of Motion, also called the Law of Inertia, states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.Choice A is incorrect because objects in motion do not necessarily stop unless a force (like friction or air resistance) acts on them. In a frictionless environment, an object would continue moving indefinitely.Choice C is incorrect because objects do not always move in circles unless a force (like gravity in orbital motion) causes them to do so.Thus, choice B correctly describes the principle of inertia—an object stays in its current state (rest or motion) unless an external force changes it.
