The answer is that the a is bigger. Not because it’s falling from higher but because it’s traveling faster. When the object hits the ground, it’s going from some speed to 0, and it has to do that in the same amount of time regardless of how fast it’s going. I am ignoring impulse here, this is actually what’s different but this is something you won’t go over just yet. So because the speed is going from x to 0 and then from 2x to 0 or whatever, in the same time, remember that acceleration is v/t, the v is bigger so the a is bigger. Transfer that bigger a over to a bigger F when using F=ma.
