Forcing another character into an obstacle does not cause damage. The Move would stop where the obstacle is.
However, an Advanced Atomic Power can have both a Move and Damage component.
Keep in mind that a character can only Move by means of its normal Movement type. A character that has Ground Movement can only move things by Ground Movement. The character cannot be Move something into the air. This would require the character had a Movement of Fly. A Power could be created to give the Movement type of Fly and then have a Move effect added to it.
