Just a heads up. I reached this tutorial just after Godot 4.2 was released.
When Kaan alters the Gravity this was the first item that I couldn’t find. They are still there. They’ve made the options more compact now though and we need to look under Accelerations for this one.
I am now stuck on the initial velocity because of this same issue. were you able to find that one?
EDIT: never mind I found it right after posting this. its under the “spawn” dropdown in velocity
nice one, there does seem to be a couple of things that have moved around, good to find out what they are and thank you for sharing 
Hi
when I move the particles stop showing any ideas?
Using Godot_v4.2.1
I fixed it by changing some setting Inherit Veiocity ratio i had somehow set to -100
