When an object is moving with a constant velocity, it implies that there is no change in its speed or direction over time. According to Newton’s first law of motion, an object will remain in its state of motion unless acted upon by a net external force. If the object is traveling at a constant speed in a straight line, it does not experience any acceleration.

Acceleration is defined as the rate of change of velocity. Since the object is not accelerating, the net force acting on it must be zero. This means that all the forces acting on the object are balanced; thus, the forces in one direction cancel out the forces in the opposite direction.

In summary, when the net force is zero, it confirms that the object is not accelerating, and when it is moving with constant velocity, it had reached a state of equilibrium regarding the forces acting on it.
