Question

If the force on an object remains constant, as the mass increases, the acceleration __________.

Answer 1

The acceleration must be decreasing. F= ma, if the force remains the same and the mass is increasing then the acceleration must decrease proportionally.

Answer 2

The correct answer is the acceleration will decrease.

Step-by-step explanation:

This refers to Newton's second law, where it is established that if a force acts on an object, the object accelerates in the sense of force.

And if the mass of this object is continuous, as the force increases the acceleration will grow. But if what remains constant is force, and what we increase is mass, then the acceleration will be less.

To understand it in a simpler way, let's think about horses and a carriage. The horses begin to pull hard from a carriage, whose mass will remain the same all the way. If this movement continues, then the carriage will start to go faster.

But suppose we change the mass of the carriage, adding two men of 100 kg each. The strength of the horses remains the same, and remains constant. But having a greater mass to move, the carriage will lose speed.
