Do these 2 lines do the exact same thing?

Is there any difference in between these 2 lines at line 9? both of them makes the bullet travel at 200 in the direction i am clicking.

 bodyvelocity.Velocity = CFrame.new(part.Position,mouse.Hit.Position).lookVector * 200
  bodyvelocity.Velocity = mouse.Hit.lookVector * 200

*part position is the position of the bullet.

full script:

local plr = game.Players.LocalPlayer
local mouse = plr:GetMouse()

mouse.Button1Down:Connect(function()
    print(CFrame.new(mouse.Hit.Position).lookVector *200)
    local part = Instance.new("Part", workspace)
    local bodyvelocity = Instance.new("BodyVelocity", part)
    bodyvelocity.MaxForce = Vector3.new(math.huge, math.huge, math.huge)
    bodyvelocity.Velocity = mouse.Hit.lookVector * 200 -- this line
	part.CanCollide= false
	part.Position = plr.Character.Head.Position 
end)
