Bezier Curve not firing smoothly

Hello developers! My Bezier Curve works but for some reason, the projectile (I am making an artillery that fires exploding projectiles) which is a sphere would move irregularly to the finish point. (it would move up and down randomly and and make a zig zag pattern, it almost seems as it is teleporting) I don’t see anything wrong with my code is there something that I can fix to make the projectile launch smoothly? Thanks!

local button = script.Parent.Button.ClickDetector
local p1 = game.Workspace.p1.Position
local start = game.Workspace.Start.Position
local finish = game.Workspace.Finish.Position

function beizercurve()
	local travel = game:GetService("ReplicatedStorage").PartReplications.Travel:Clone()
	travel.Parent = game.Workspace 
	
	local function lerp(a, b, t)
		return a + (b - a) * t 
	end
	for i = 0,100,1 do
		local t = i/100
		local l1 = lerp(start,p1,t)
		local l2 = lerp(p1,finish,t)

		local quad = lerp(l1,l2,t)
		travel.Position = quad 
		wait(0.01)
	end
end

button.MouseClick:Connect(beizercurve)

Heres a video of the Bezier curve:

Is it anchored? It’s a mistake a lot of people make. Also I suggest you look into parabolas. I made a module for this using this post, Modeling a projectile's motion, but I think you can use the post instead of the module.

Thank you very much that made the curve smooth however, for some reason the bomb wont explode when it detects collisions. Is there any way to solve this?

You can use AssemblyLinearVelocity as shown in the basket ball example. Or raycasting if you still want to use cframes, but i suggest keeping the projectile unanchored and using velocity as its smoother and you can detect collision easier.
