It depends on what you mean by "strong force" and "heavy force."

* Force and Acceleration: Force causes acceleration (a change in velocity). The more force you apply, the more an object accelerates.

* Mass and Acceleration: The heavier an object is (more mass), the less it accelerates for a given force.

So, to answer your question properly, we need to be more specific:

* Same Force, Different Masses: If you apply the *same* force to a light object and a heavy object, the light object will accelerate faster (meaning it will reach a higher speed quicker).

* Different Forces, Same Mass: If you apply a stronger force to the light object compared to the heavy object, it's possible the light object will go faster *initially* (because of the greater acceleration). However, the heavy object will *eventually* catch up if the force is applied for a long enough time.

Example:

* Imagine pushing a small toy car and a large truck with the same amount of force. The toy car will accelerate faster and go faster initially.

* But if you keep pushing the truck with more force than the toy car, the truck will eventually be going faster than the toy car.

In Conclusion:

* Force: More force = faster acceleration.

* Mass: More mass = slower acceleration for a given force.

To give you a definitive answer, you need to tell me if you're comparing the forces applied or the masses of the objects.
