No, if there were no forces acting on a moving object, it would not keep going. According to Newton's first law of motion, also known as the law of inertia, an object at rest tends to stay at rest, and an object in motion tends to stay in motion with the same speed and direction unless acted upon by an external force.
In the absence of any external forces, an object in motion would continue to move at a constant velocity. However, it is important to note that this motion would eventually be affected by other forces present in the environment, such as friction or air resistance. These forces would eventually slow down the object and eventually bring it to a stop.
In reality, it is difficult to completely eliminate all forces acting on an object. Even in space, objects can experience gravitational forces or slight influences from other celestial bodies. Thus, the idea of a perfectly isolated object with absolutely no external forces is purely theoretical.
