Your intuition is correct. According to Newton's second law of motion, which is a fundamental principle in classical mechanics, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. Mathematically, it can be stated as:
F = ma
where F represents the net force, m is the mass of the object, and a is the acceleration.
If there is no net force acting on an object, according to Newton's second law, the acceleration of the object will be zero. Therefore, if the force acting on an object stops, the net force becomes zero, and the object will cease to accelerate. It will either come to a complete stop or continue moving at a constant velocity, depending on any other forces that might be present.
It's important to note that in reality, there are often multiple forces acting on an object simultaneously. In such cases, the net force is the vector sum of all the individual forces. If the net force becomes zero, the object will no longer accelerate. So, your intuition aligns with the principles of Newtonian physics.
