It's called a reverse side-kick because he lands with his foot in the front and then steps. If his foot would land in the back, it would be call a spin side kick. This is in Taekwondo terms, if you ask another martial artist from another style, they will probably give you a different answer.

Hello,

Me and my friend watched a video where two characters fight against each other. However, there two moves in the video my friend and I wondered what they are called.



At 1.08 Sub-Zero (the man in blue) turns around and kicks Scorpion a few feet back, then right after that at 1.10 he jumps toward a tree branch and uses his own momentum to kick Scorpion twice on the chest with his movement.
