How to smooth out parabolic motion?

You can write your topic however you want, but you need to answer these questions:

  1. What do you want to achieve? Keep it simple and clear!
    I am attempting to make a cannon that shoots in an arc. I can make the part do an arc well but for some reason it is lagging a lot eve though it is using stepped.

  2. What is the issue? Include screenshots / videos if possible!

The part is lagging a lot while its in flight but when It disconnects from the stepped it is fine.

  1. What solutions have you tried so far? Did you look for solutions on the Developer Hub?
function ProjectileService:FireProjectile(startingPos, Force)
	local projectile = script.Projectile:Clone()
	projectile.Position = startingPos
	projectile.Parent = workspace
	local connection
	local startTime = workspace.DistributedGameTime
	local startingV = 100
	local startingH = startingPos.Y
	connection = RunService.Stepped:Connect(function()
		local timeinSeconds = workspace.DistributedGameTime - startTime
		--currentHeight = quadratic coefficent * gravity(m/s^2) * TimeInSeconde^2 + (StartingVelocity m/s^2 * TimeInSeconds) + height
		local currentHeight = (-.5) * (54.936) * (timeinSeconds^2) + (startingV * timeinSeconds) + startingPos.Y
		projectile.CFrame = + 1, currentHeight, projectile.Position.Z)
		if currentHeight <= -1 then

Are you doing this on the client or the server? Visual things like this can be smoother when done on the client. Also, I think replacing stepped with renderstepped would be worth a try.
