Final answer:
Newton's 2nd Law states that an object accelerates if a force acts on it. If there is no acceleration, then no forces are acting on the object.
Step-by-step explanation:
Newton's 2nd Law, also known as the law of acceleration, states that an object will accelerate if a net force acts on it. The acceleration of an object is directly proportional to the net force applied and inversely proportional to its mass.
Therefore, if forces are acting on an object, it will accelerate. An object can only accelerate if a force acts on it. If there is no acceleration, then no forces are acting on the object.
To summarize, forces are necessary for acceleration to occur, and if there is no acceleration, there are no forces acting on the object.
