Any help is appreciated.

my part fall like this* 30longchar

You can use CFrame.lookAt and AssemblyLinearVelocity.

local part: BasePart
local cframe = CFrame.lookAt(part.Position, part.AssemblyLinearVelocity + part.Position)

I agree with @busterbob64’s approach to for obtaining the desired CFrame and I would tilt the object towards its direction of motion with a BodyMover.

#5 
task.spawn(function()
	while task.wait() and start do
		missile.missile.CFrame = CFrame.lookAt(missile.missile.Position,missile.missile.AssemblyLinearVelocity+missile.missile.Position)
	end
end)

It doesn’t work for me :thinking:

Try using Heartbeat or BindToRenderStep.

See RunService.

#7

Nothing changed

task.spawn(function()
	game:GetService("RunService").Heartbeat:Connect(function()
		missile.missile.CFrame = CFrame.lookAt(missile.missile.Position,missile.missile.AssemblyLinearVelocity+missile.missile.Position)
	end)
end)

If you are using the CFrame to create the animation, then you can use the previous position to calculate the direction in which your object should look

task.spawn(function()
	local prevPosition
	while task.wait() and start do
		prevPosition = missile.missile.Position
		missile.missile.CFrame = -- your position calculation
		missile.missile.CFrame = CFrame.lookAt(missile.missile.Position, prevPosition)*CFrame.Angles(0,math.pi,0)
	end
end)
#10 
task.spawn(function()
	local last_position
	while task.wait() and start do
		last_position = missile.missile.Position
		missile.missile.CFrame = CFrame.lookAt(missile.missile.Position,last_position)*CFrame.Angles(0,math.pi,0)
	end
end)

It just disappeared when I test it
this is my full code:

local missile = workspace.missile
local stuff = game.ReplicatedStorage.missile.stuff
local start = false

task.wait(4)

missile.missile.missile_fire:Play()
missile.missile.Anchored = false
missile.missile:ApplyImpulse(Vector3.new(0,500000,500000))
missile.missile.missile_fly:Play()
start = true

task.spawn(function()
	local last_position
	while task.wait() and start do
		last_position = missile.missile.Position
		missile.missile.CFrame = CFrame.lookAt(missile.missile.Position,last_position)*CFrame.Angles(0,math.pi,0)
	end
end)



task.spawn(function()
	while task.wait() and start do
		local cloned_stuff = stuff:Clone()
		cloned_stuff.Parent = missile.missile
		cloned_stuff.CFrame = missile.missile.CFrame
	end
end)
