I was wondering how I could "Throw" a part. How can I do that?

local Tool = script.Parent
local Baseball = Tool.Handle

function plant()
    local baseball2 = Baseball:Clone() 
    local spawnPos = Baseball.Position
    baseball2.Position = Vector3.new(spawnPos.x, spawnPos.y, spawnPos.z)
    baseball2.Anchored = false
    baseball2.Parent = workspace
    baseball2.Size = Baseball.Size
    baseball2.Shape = 0
    baseball2.BottomSurface = 0
    baseball2.TopSurface = 0
    baseball2.Reflectance = 0
    baseball2.Name = "TimeBomb"
    baseball2.Locked = true
    baseball2.CanCollide = true
    baseball2.Transparency = 0
     -- How can I make the part go up in the air.
end
