exactly the same. this is the classical definition of force, and scaling is pretty much a change of variables

You mean twice as easy or am I missing something? Two times the mass with the same acceleration and the object still moves with the same force as before.

It doesn't even make any logical sense when you think about it. "F = ma" is an equation. If you multiply only the other side of the equation by two but not the other side, it no longer is an equation is it, unless both sides were zero.

You have to be clear about what you are keeping fixed when you change things like this. If you change it to F=2ma, then everything is the same if everything has half the mass as before, so you basically just changed the definition of mass.

A better way to ask the question I think you want to ask is: how would the world be different if all fundamental particles had double the mass they do now, but everything else stays the same?

That dude above literally has no clue. Force written like that not an observable, thus modifying the equation just changes the definition of force, thereby depriving it of direct physical interpretation. The laws of nature remain unchanged.

Even if you were programming a video game with any arbitrary physics that you wanted, you STILL could not make it so that F would be equal to two times 'ma'. What you could do is to say that two times force is equal to two times mass times acceleration. Even if you had a crazy physics engine where it would take huge amount of force to move a feather, that would just mean that the feather actually has huge amount of mass. Maybe it's made out of neutron star material or who knows what. Another possibility is that you are accelerating the feather at an incredible speed.

I mean, just like you can say F = ma, you could also say m = F/a. You see that the left side of the equation was hiding on the right side. So you can't just change one variable in the equation without affecting the others, they are all interconnected. If mass is going to get doubled, either acceleration or force is going to need to be modified. There's no escape from that.

Here's an illustration. If Jack works and he earns ten dollars per hour and John works and earns 20 dollars per hour, and they put the money to a box and give it to Tom. If you double the money that Tom has in the box, you need to make either Jack or John to work harder. All of those things are interconnected and it's the same thing with the equation F=ma.

Are you unable to entertain hypotheticals? F=2ma would be in a hypothetical universe, not this universe. This universe won't let you do that.

Some people ask what would happen if the Gravitational constant were a different value. If it's too small the universe would fly apart. Too big and it would collapse into a black hole. Same thing, it's a hypothetical question.

Both of you fundamentally do not understand what he is trying to say because you have no conception of units. So, let me ask the obvious question first.
If F=2ma, then the question simply becomes whether for example F = -dV/dx remains true. Cause if it does, it will ultimately mean everything will just rescale: yes, everything will be twice as heavy, but everything will produce twice the energy, so it would be indistinguishable from changing units. The issue with your analogy is that classical mechanics is a parameter free theory; there are no universal constants in it, and only relative masses matter. So if all masses double, nothing changes.

the big difference would be if F_gravity = mg while F = dp/dt = ma (in the special case that mass doesn't change)

Yeah and here's the thing. Mass, for example, is not some independent thing that exists in the universe, being independent of force and acceleration. That's because you can re-arrange the equation so that mass is equal to force divided by acceleration. So mass is the property of an object which tells you how much force it takes to accelerate it for given value of acceleration. Of course this assumes that the acceleration and force happens in a vacuum, so there's no other variables like air resistance affecting the situation.

Exactly the same except mass is defined as twice as much as it is defined now.

This.

Mass already is kilograms in this equation, so in the equation is F= 0.001*m*a if you're working with grams. 2.20462*m*a if you're working with pounds, etc.

You could have force being equal to million times m*a and it would change nothing except you would be using bigger numbers. You would be just saying that the normal newton becomes a million newtons without changing the actual force. It's like newtons experiencing inflation. Normally you would need one newton to move a one kilogram mass at one meter per second squared, but after inflation you need a million newtons instead. You have one kilogram dumbbell and you accelerate it at one m/s^2 and for no reason you multiply that by million to get million newtons of force for something that even a fat person can do. Or in OP's case you'd need twice as many newtons and likewise it would change nothing in the physics.

So all in all: OP is not changing a parameter like gravitational constant, instead it's a change of the definition of force in physics.
