Teleportation and Momentum

[elyktsorb]

So. I want to know if teleportation spells can nullify momentum. To clarify, my character may attempt to grapple a creature off of their winged mount and then suplex them into the ground (which is some several hundred feet below us). Now the reason my character is doing this, is because they are a Barbarian, and if they're raging, the most damage they could take from the fall (20d6 being the max fall damage) would essentially be 10d6 instead, which is significantly more livable.

Basically what I want to know is if teleportation spells cancel momentum and nullify fall damage since I have a feeling if my character does this, and the other character can teleport and it does cancel the fall damage, then they probably will.

It would depend on the teleport? I would imagine misty step not conserving momentum but arcane gate totally thinking with portals.

[MrStabby]

Depending on what happens to momentum, teleporting to the other side of a planet could be lethal.

I would just hand-wave it away.

The rules never say, which means this is one of many cases in 5th edition where the only possible answer is "ask your DM".

[Keravath]

The rules don't say. However, I think that teleportation would have to nullify momentum since teleporting any reasonable distance in a rotating world moving through space like ours would not work without a lot of collateral damage.

This depends on what sort of physics you want to invoke for your world but most interpretations of teleportation seem to leave the people/objects being teleported at rest (not moving) relative to the reference frame of their destination.

I second the desire to see Arcane Gate acheive Portal like shenanigans.
