why are no scripts working inside my projectiles?

local Tear = game.ReplicatedStorage:WaitForChild("tear")
local plr = game.Players.LocalPlayer

local UserInputService = game:GetService("UserInputService")

local speed = 110

UserInputService.InputBegan:Connect(function(input, gameProcessedEvent)
    if not gameProcessedEvent then -- if player is not typing
        if input.KeyCode == Enum.KeyCode.E then
            local char = plr.Character
            if not char or not char.Parent then -- if player's character hasn't loaded
                char = plr.CharacterAdded:Wait()
            end

            local tearclone = Tear:Clone()
            tearclone.Parent = workspace

            tearclone.CanCollide = true
            tearclone.Anchored = false
            tearclone.CFrame = char.Head.CFrame + char.Head.CFrame.LookVector

            tearclone.AssemblyLinearVelocity = tearclone.CFrame.LookVector * speed
        end
    end
end)

theres a custom body velocity in the projectile too. when i try to put a damage script in the projectile, the script doesnt work. if i check the projectiles, i can see that the damage script is indeed in them but toesnt work for some reason. i dont want to modify the script above, it would be better in i could script the projectile instead.
