Answer Details
The statement "If no net force acts on an object, the object maintains a state of rest or constant speed in a straight line" is a statement of Newton's first law of motion. The first law of motion, also known as the law of inertia, states that an object at rest tends to stay at rest, and an object in motion tends to stay in motion with a constant speed and in a straight line, unless acted upon by a net external force.
