I guess what I’m looking for is the smallest force that can be applied in which the next instant after the force is initiated, the object is at a different location. How do you find this force applied at initiation? If this is not what I’m looking for but someone guesses that I may Be looking for something else, please inform me on what this may be. I think this cannot be solved since there seems to not be such thing as “next instants’” since there are infinite numbers in between any two numbers.
