Final answer:
The statement is false. Based on Newton's First Law of Motion, objects remain at rest or continue to move at constant speed in a straight line unless acted upon by an external force, implying the property of inertia.
Step-by-step explanation:
The statement that objects naturally stay at rest and will slow to a stop if put in motion is False. This might be the perception in our everyday experience where friction and air resistance often stop motion. However, Sir Isaac Newton's First Law of Motion states that an object will remain at rest or continue to move at a constant speed in a straight line unless it is acted upon by an external force. This denotes the concept of inertia. In an environment devoid of external forces like friction, such as space, once an object is moving, it will continue to move indefinitely.
