If an object's velocity remains constant, it means that the object is moving at a constant speed in a straight line without any changes in direction. In such a scenario, according to Newton's first law of motion (the law of inertia), the net force acting on the object must be zero.
Newton's first law states that an object at rest will remain at rest, and an object in motion will continue to move at a constant velocity unless acted upon by an external force. When an object is moving at a constant velocity, it means that the forces acting on it are balanced, resulting in zero acceleration. Therefore, the net force on the object is zero.
In simpler terms, if an object's velocity remains constant, there is no net force acting on it, and the forces pushing or pulling in different directions are balanced, allowing the object to maintain its constant velocity.
