• What happens to the net force acting on it?

answer/question/discussion: ->->->->->->->->->->->-> : It stays the same.

#$&*

• What happens to its acceleration?

answer/question/discussion: ->->->->->->->->->->->-> : It should be constant.

#$&*

• If it dropped from a much higher point, what would happen to the net force and the acceleration?

answer/question/discussion: ->->->->->->->->->->->-> : Eventually, it would start to change and get larger.
