What's a better way to implement a knock back system?

Currently I have a tool that knocks back a player on hit. However, I noticed the knock back is very inconsistent and isn’t very fluid. Their is a ton of velocity fluctuation and the knock back is just wonky.

here is my current script I’m using

local part = script.Parent

function onTouch(hit)

	if hit.Parent == nil then return end
	local h = hit.Parent:FindFirstChild("Humanoid")
	if h ~= nil then

		print"player"

		local player = hit.Parent.HumanoidRootPart

		if not hit.Parent.HumanoidRootPart:FindFirstChild("BodyVelocity") then

			local bv = Instance.new("BodyVelocity", player)
			bv.MaxForce = Vector3.new(math.huge, math.huge, math.huge)
			bv.P = 500
			bv.Velocity = script.Parent.CFrame.LookVector*50
			
			wait(0.2)
			bv:Destroy()

		end

	end
end
part.Touched:Connect(onTouch)

What are some other methods I can do to make a better system? Or how can I improve on my current system?

Module s will make your life easier to do it and you should use

Game:GetSerivce('Debris'):AddItem(bv,0.2)
