How do I check if player is falling down?

So, Im making a game about jumping and I want to set the gravity to a number when the player is ascending after jumping and set another gravity for when the player is descending, so It doesnt take too long for the player to land again.

This is the part of the script I need help with

local debounce = false
local character = script.Parent
local humanoid = character:WaitForChild("Humanoid")
local player = game.Players:GetPlayerFromCharacter(character)
local leaderstats = player:WaitForChild("leaderstats")
local jumps = leaderstats.Jumps
print("Found leaderstats")
humanoid.UseJumpPower = true

debounce = false 

local graviti = Instance.new("IntValue")
graviti.Value = 1000

local graviti2 = graviti.Value



humanoid.Jumping:Connect(function(Start)
	if humanoid.JumpPower >= 1000 and game.Workspace.Gravity > 50
	then game.Workspace.Gravity = game.Workspace.Gravity - 5
		jumps.Value = jumps.Value + 1
		print("ok")
		graviti2 = graviti2 - 5
		print(graviti2)
		wait(1)
	humanoid.StateChanged:Connect(function(old,new)
		if new == Enum.HumanoidStateType.Freefall then
			game.Workspace.Gravity = 1000
			print("Falling")
		end
	end)
		humanoid.StateChanged:Connect(function(old,new)
			if new == Enum.HumanoidStateType.Landed then
			game.Workspace.Gravity = graviti2
			print("landed")
			end
		end)
	end
end)
