Answer: The correct answer is B. objects keep moving at constant velocity unless forced to change.
Step-by-step explanation:
Newton's First Law of Motion, also known as the law of inertia, states that an object at rest will stay at rest, and an object in motion will continue moving at a constant velocity in a straight line unless acted upon by an external force. This means that no force is required to keep an object in motion with a constant velocity. Option B accurately represents Newton's First Law of Motion.
