To determine which objects will accelerate, we need to consider the net force acting on each object. The net force is the vector sum of all the individual forces acting on an object. If the net force is non-zero, the object will experience acceleration according to Newton's second law of motion.

The second law of motion states that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. Mathematically, it can be expressed as:

F net = ma

where F net is the net force, m is the mass of the object, and a is the acceleration.

Now, let's analyze the statement in the question:

"an object accelerates only if the forces acting on it in one direction are greater than the forces in the opposite direction"

If the forces acting in one direction are greater than the forces in the opposite direction, then the net force will be non-zero, and the object will accelerate.

Therefore, based on this statement, all objects will accelerate if the forces acting on them in one direction are greater than the forces in the opposite direction. None of the objects will be an exception.

In general, when the net force acting on an object is not zero, it will undergo acceleration. However, when the net force is zero, the object will either remain at rest or continue to move with a constant velocity (if it was already in motion).
