[QUOTE="Cap'n Kobold, post: 7079613, member: 6802951"] In general, yes. To break that such as by protecting the object against gravity would require something outside our current understanding. Something like magic. I generally assume that physics works in D&D mostly the same as real life, - until magic gets involved. I think that trying to combine RL physics with a nit-pick reading of the precise rules of a spell isn't generally going to be useful however. Its magic. Go with the intent of the spell or whichever interpretation is most interesting. When you're talking about actual matter however, there is a lot of difference however. Simple practical example: you have to exert force against an object with mass to start it moving even if its weightless. You would feel resistance, like pushing something on frictionless wheels. When you stopped pushing, the object would continue moving until another force, even just air resistance changed its velocity. Pushing against a massless object, the only resistance you would feel is the air resistance, which would stop it moving as soon as you stopped pushing it. When someone casts levitate for example, they can be effectively weightless, but I think that they still retain their mass. Do you distinguish between violent movement of the sphere caused by impact with the ground, and violent movement of the sphere caused by impact with a dragon's tail for example? [/QUOTE]
