Realistically, it's technically sideways. To reach orbit you need to go sideways, not up. Theoretically you could escape Earth's gravity influence by going straight away from it, but it's not the realistic way that works.

Actually, you go up. Then the earth rotates beneath you, turning your up into sideways.

Technically a spiral because you start with orbital momentum just from standing still on the surface of earth when starting. You'd have to intentionally offset that to go straight but that's not the most efficient way

No, not really. The velocity needed for low Earth or it is 7.8 km/s. The speed of rotation on the surface of earth is 0.46 km/s. You need to go sideways a lot more than you need to go up. You do need to go up some, but it's pretty minor in comparison. Watch a rocket launch. They go up at the start, but start burning toward the horizon pretty quickly.
