RapidLearningCenter.com © Rapid Learning Inc. All Rights Reserved College Physics - Problem Drill 06: Newton’s Laws of Motion Question No. 1 of 10 Instructions: (1) Read the problem and answer choices carefully (2) Work the problems on paper as needed (3) Pick the answer (4) Go back to review the core concept tutorial as needed. Question 01 1. Which of the options best describes the statement: Every object continues in a state of rest or uniform motion in a straight line, unless it acted upon by an outside force. (A) Newton’s second law of motion, the law of inertia. (B) Newton’s first law of motion. The tendency to keep moving is called inertia. (C) For every action there is an equal and opposite reaction. (D) Newton’s first law of motion, the law of action and reaction. (E) Newton’s third law of motion, the law of inertia. Feedback on Each Answer Choice A. Incorrect! This is not Newton’s second law. B. Correct! This is a statement of the Newton’s first law of motion, which is often called the law of inertia. C. Incorrect! For every action there is an equal and opposite reaction is a statement of Newton’s third law. D. Incorrect! The statement does describe Newton’s first law of motion, but it is not about action and reaction. E. Incorrect! Newton’s third law is not the law of inertia. Solution Newton’s laws are: Newton’s First Law of Motion (the law of inertia): Every object continues in its state of rest, or uniform motion in a straight line, unless acted upon by an outside force. Newton’s Second Law of Motion: F net = ma Newton’s Third Law of Motion: For every force there is an equal and opposite force. For every action there is an equal and opposite reaction. The correct answer is (B).
