How to make a brick move with a script?

for i = 1,10 do
Workspace.Part.Position = Workspace.Part.Position  + Vector3.new(i,0,0)
wait(0.5)
end

This will move it 10 studs on the x axis.

Correction:

for i = 1,20 do
script.Parent.Position = vector3.new(i, 0, 0)
wait(0.5)
end

This is an easier way, paste it into the brick. Or you can do this to have it run by it not being in the script.

for i,20 do
game.Workspace.BRICKNAME.Position = vector3.new(i, 0, 0)
wait(0.5)
end
