Description
Since my previous comic was too mature for most groups, I'm now trying it with a series of comics which is suited for all ages. This one is just a test-balloon (since a test-rock would obviously be too heavy to fly
). If this one gets enough positive feedback, I'll very likely make more of these. At least I've got quite a few ideas floating around in my head.Of course, there are multiple possible explanations how this actually works, but I leave this open as an exercise for the reader.

No, it'd cause Twilight to suddenly sink into the floor.

one does not lift the rock, one simply asks the rock to lift itself (it's fun to be serious sometimes, isn't it ) (wait a minuet, is pony physics serious )

The physics is all correct; but the forces are acting on the rock and the magic field its self. It is my headcannon that magic is a bridge between matter and energy. In the case of levitation the magic field cancels out the effects of gravity on the object within. Then to move said object, the field exerts a gravitational force in the desired direction, and as the object is weightless, the force only needs to overcome inertia.

Alright, when using magic to "lift",
one isn't using the focal point of delivery of magic as a fulcrum.
More along the lines of removing the gravitational pull upon said idem.
Also, must be able to "feel" the amount of force needed at all axises & on each part of the surface.
One doesn't wish to crush a side while nonsupporting another.
It is like encasing the idem in a telekinesis skin.
So the larger & heavier an idem is,
The more one would need to focus, to generate the accommodating field to do so.
Hence why one using magic, just can't normally will it into use.
(There are some naturally pure/innocent beings that perform this as if it were second nature. But that isn't the case now.)
Just as one would practicing martial-arts.
One can't use there limb to break a brick from the first day. One must build up to it.
It takes practice,strengthening & focus to do it.
Magic is a fluid type of energy/force, it normally flows throughout all life.
Unicorns are built to naturally channel this energy to a focal point which their horn.

Of course you are assuming that horns are made of materials that are A able to break and B really are the part that is exerting the force.
To A: If the horn is made, lets say, of CNTs with a coat of graphene, it would easily withstand such forces. Now the next question is, would the skull be able to?
To B: If the horn is not the actual part that is exerting the force but more like a switch that makes the world itself exert the force there would be no or little physical feedback. As we know almost nothing about MLP this is just as possible as that all the stones are made of marshmallow or that the magic does not actually move the rock but the room around it.

As a hypothesis, your comic is directly contradicted by a large amount of observational evidence. Time to rethink.

I love science right now. That's so how Newton's law would work on a pony trying to lift something heavy.

Except she's not using her horn as a lever.Β She's using it as a tool for channeling the energy required to lift the rock.Β I'd sooner expect her to burn out or something.

As done in Too Many Pinkie's when she performed the spell over and over again her horn was glowing redish white and blew on it as if it was recently burning hot from doing that spell so often.

I think you both are interpreting way too much into this comic

Hush can't you see we're debating about your comic? Here's a bag of gold bits. Have fun.

Well... if we go into ''arcane-science'' stuff...
One could say that all that 'magical energy focused on one point', or ''spell'', is creating an anti-gravity field that negate the effect of gravity within a defined/closed space.
Of course, the amount of energy, or ''magic'', to generate such field AND maintain it would be enormous, but we are talking of one of the greatest unicorn of this generation. I say it's well within her range.

A 3rd-law consistent solution that does not involve horn-breakage would be pulling the force from somewhere else. Β e.g. a coupled second magic force that pushes Equestria down. Β Newton's 3rd does not specify where the forces are located, only their direction and magnitude.

Poor Twilight, this is just bad.
But I don't think that's theΒ case, I think it's more like the rock cannot be lifted at all and the horn gets burned out, white hot like a machine gun keep on firing without allowing it to cool down for a while.

You definitively have all my positive feedback for today. Do it!

The hard part about magic isn't lifting a boulder: it's stopping your brain trickling into your boots when you do it. (Paraphrased from Terry Pratchett).
Did you notice how her feet sunk into the ground when she lifted it? That's one of the things that got me hooked on the show.
π: 0 β©: 1
Yeah, those neat details are what also makes me love the show

Unless you can anchor that reflection to another object... such as a lever.

Looks good - but the more you think about it, the more confusing it gets
The horn breaks because it cannot support the rock - but Twilight still manages to hold up her head.
So maybe her horn has suffered from the industrial grade magic Twilight channels through her consumer grade horn and became brittle... But that explanations is rather sad - corneoporosis at this young age ?
Second thought: the horn still needs to support the rock but is itself supported by magic - this may seem like circular logic but would have a logical consequence. You can shoot anything from your horn as it only channels your energy but to lift things heavier than you, you need a supporting magic field around your horn to work against the effect of Newtons third law of motion. Yes... thats a good solution.. I like that solution... And why did the horn break in this case ? Because Twilight made the field strong enough but forgot about the maximum weight rating for her horn...Β
I may be thinking to much about this... this will haunt me in my sleep...

Well, in fact, if you zoom in very close to on the horn, you can read the text "Caution: Maximum load 500 kilos"

Newton's third law is quite a doozy. To every action there is always an equal and opposite reaction;Β The forces of two bodies on each other are always equal and are directed in opposite directions.
