Question

Hi I wanted to make an object’s gravity augment progressively to make it fall faster as time goes on

I tried

extends Node2D
var current_gravity = ProjectSettings.get_setting("physics/2d/default_gravity")
func _ready():
	pass

func _process(delta: float) -> void:
	current_gravity += 10

but every instance of the item when created falls at the same speed

Try this:

extends Node2D

var current_gravity = ProjectSettings.get_setting("physics/2d/default_gravity")

func _ready():
	pass

func _process(delta: float) -> void:
	current_gravity += 10 * delta

You just needed to multiply the 10 by delta.

Multiplying by delta as suggested by @KingGD is a good idea.
But you are still only changing the value of the current_gravity variable. You need to set that value back to the physics engine to have any effect.

extends Node2D

var current_gravity = ProjectSettings.get_setting("physics/2d/default_gravity")

func _process(delta: float) -> void:
	current_gravity += 10 * delta
	ProjectSettings.set_setting("physics/2d/default_gravity", current_gravity)
