Yeah, but Rotom might not tell you the entire truth. Cosmoem might nearly a ton but it floats constantly, negating that weight.
Physics doesn't work that way.
Cosmoem floating makes it weightless, not massless. All that means is that Lillie doesn't have to fight to keep her bag in the air, but when she walks she still has to exert force to accelerate a 999.9kg object in whatever way she wants to go.
There's something not quite right with the repels that girl uses.

As if lighter-than-air Wailord blimp wasn't bad enough, now we have stellar-core Cosmoem, who can give Kancolle girls (assuming anime kiloton weight measurements) a run for their money.

Lillie carries a Float Stone with her all the time, it's the only explanation.
Edit: I did check the weight of Cosmoem (I got to that point in the game, I was trying to avoid spoilers earlier) and what the fuck, 2.2k pounds. And it's only 4 inches.

Mass does not relate with force needed to move an object in state of weighlessness. That's why that ion engine works: In zero gravity where friction and gravity very, very close to zero you only need a small amount of force to start moving since there's no need to overcome initial movement friction like on earth; thus one could (theoretically) start a cascade reaction from a marble, golf ball, billiard ball and bowling ball with just small amount of force (there'll still be some forces loss when the balls struck each other because the contact). Applying this to Nebby's condition, which we know does not adhere to normal physics (in order to float you must displace your own weight to the surroundings, like helicopter produces upward and downward force by propeller to displace its own weight, the weight of a balloon was displaced by the hot air, etc) like any other heavy pokemon that can float (Metagross, Dialga, Palkia etc) you don't need anymore force than to move the bag containing it.

Even if you can start moving, however, that still makes things extremely awkward and dangerous. It would take several seconds or even minutes to get a multi-ton object up to walking pace, and it takes a similar amount of force to stop. That means you need to plan your taking a turn around a few trees in a forest very, very carefully to prevent momentum from dragging you into one.
Walking along a flat plain and suddenly it has a downhill slope you didn't see? You'll be hovering from the bag that still has momentum moving forward, and you'll be unable to impart any new force except by wiggling and squirming.
Really, it opens up a whole can of physics worms to simply shut off a basic feature of "common physics" we experience on Earth.
I do love Danbooru and its intellectual discussions about the laws of mass and the relationship objects of mass share with one another in the universe... and how Pokemon takes a big middle finger to all of that to allow a little girl to carry around a condensed star in her bag.

Sure it does. Newton's Second Law and all that. F = ma*, remember?
Absence of a gravitational field (or free-falling in a uniform gravitional field) doesn't change the above. Only difference is that you don't get surface friction because those are dependent on the normal force (which counteracts the gravitational force pressing you down on the surface, as per Newton's Third Law).
(*Moving at relativistic speeds is a bit different though, as we would be dealing with relativistic, not classical mechanics. In that case Newton's Second Law is modified to F = dp/dt = γ(v)³m₀a|| + γ(v)m₀a⊥)

The only difference is that you don't need some minimum threshold 'force' to overcome static 'friction', and you don't need to apply a constant thrust to overcome friction and drag. Once you apply enough force to accelerate the object to a velocity you want, it remains IN MOTION at the same velocity (assuming other forces are negligible). You still need to apply force to speed up, slow down, or change the direction of said object in any manner because these are all vector changes, and this force is given by F = ma.
(Really, a lot of high school level Physics exercise and exam questions will ask you to just straight-up ignore friction and drag anyway [this is implicit if the question doesn't give you the coefficient of friction and drag] for calculations. F = ma still applies.)

I don't see how this is related — this is a case of conservation of momentum instead. For objects in the macroscopic scale no collision will be perfectly elastic and hence some of the kinetic energy will be lost in the form of heat (i.e. converted into vibrational energy). Even without air resistance the balls will still rapidly lose kinetic energy as they collide with each other and other surfaces.

Strictly speaking the helicopter does not "displace its own weight". It is a heavier-than-air-craft, not a blimp. Its rotors generate lift to counteract the gravitational pull to remain aloft. As per Newton's First Law if all forces are balanced (i.e. net external force of zero) then the object remains at rest or in uniform motion in a straight line.
Also as per the Second Law, heavier objects are less maneuverable, as you need more force to change direction. Even if the Pokemon can float, it just negates the gravitional pull, so they still need thrust to propel themselves forward, backward or sideways/orthogonally. And the thrust required scales up linearly with increasing mass. They are basically like Maglev trains.
(Heck, they still suffer from drag because of air resistance, so they need constant forward thrust in the first place just to maintain constant velocity)

It must has some way to allow it to negate mass, and not just weight. Some way to fuck with the Higgs field, for example, like Mass Effect's Eezo. Of course, at this point, we are talking about speculative Physics, and Pokemon isn't exactly hard Sci-fi. Still makes it fun to discuss though.

I know, right? They're trying to bring realistic physics into a world full of magic and monsters.
