If an object doesn't accelerate, spin, or change direction, and there are no external forces acting on it, it will indeed remain in a state of equilibrium. In this state, the object's velocity will remain constant.
Equilibrium refers to a state where the net force acting on an object is zero. When an object is at rest or moving at a constant velocity, the net force on it is zero. In such a scenario, the object will continue to move in a straight line with a constant speed and direction until an external force is applied to it.
So, if the object's velocity is zero (stationary), it will remain at rest until acted upon by an external force. If the object has a non-zero velocity (moving), it will continue to move in a straight line at a constant speed until acted upon by an external force.
However, it's important to note that if the object collides with something else, the collision will introduce a force and can cause changes in the object's velocity, direction, or both, depending on the nature of the collision.
