is there a way to make a ball gradually stop?

Hi, I just wanted to know if there is a way to script ball inertia(make the ball gradually stop to a halt) I tried doing this but it doesn't seem to work.

    Tool.Handle.Velocity = v * 10
    for i = 1, 30 do
    Tool.Handle.Velocity = Tool.Handle.Velocity - Vector3.new(0.1, 0.1, 0.1)
    wait(.3)
    end
    Tool.Handle:Remove()

So the handle is a simple ball, I wanted to make it so that once the ball was thrown, it's velocity would slowly decrease until it's not moving horizontally anymore. Usually the ball would just keep rolling forever if it never hits anything.
