According to Newton's first law, what will happen to the rock?

ccording to Newton's first law, an object at rest will remain at rest, and an object that is moving will continue to move in a straight line with constant velocity, if and only if the net force acting on that object is zero. Newton's first law is sometimes called the law of inertia. If the net force on an object is zero, then the object is in equilibrium.<br /><br />Apply: Imagine a rock moving in space with no forces acting on it. According to Newton's first law, the rock will continue to move in a straight line with constant velocity.
