If there is no friction in a rollercoaster is the speed the same throughout?

no because different Surfaces have different friction and that causes a Speed difference on each surface

If there is no friction, the roller coaster would keep moving forever but a constant velocity. The only way it would accelerate is if there was a force continually pushing on it.
