You are absolutely correct! That statement is a perfect description of Newton's First Law of Motion, also known as the Law of Inertia.

Here's a breakdown of the key points:

* Inertia: The tendency of an object to resist changes in its motion.

* Rest: An object at rest will stay at rest unless a force acts on it.

* Constant Speed: An object moving at a constant speed in a straight line will continue to do so unless a force acts on it.
