How do I slow down a BodyPosition on a part?

I'm attempting to make moving clouds and the speed of the bodyposition is going very fast. Unfortunately, the bricks are big and has some weight on them so I cannot lower the maxforce.

	local bp = Instance.new("BodyPosition", cloud)
	bp.Position = Vector3.new(cloud.Position.X, cloud.Position.Y, 2000)
	bp.D = 1000
	bp.MaxForce = Vector3.new(40000000, 40000000, 40000000)
	
	local bg = Instance.new("BodyGyro", cloud)
	bg.D = 6400
	bg.MaxTorque = Vector3.new(400000, 400000, 400000)
	bg.P = 400

instead of using a body position, use a for loop to make the part move along
