Answer to Question #7288 in Mechanics | Relativity for Kourt
You are told that an object has zero acceleration. Which of the following is true: the object is at rest, the object is moving with constant velocity?
The both of this claims is correct. It’s result of first Newtone’s law: Newton's First Law (also known as the Law of Inertia) states that an object at rest tends to stay at rest and that an object in uniform motion tends to stay in uniform motion unless acted upon by a net external force.
