how to stop motion smoothing with GetAxis?

I just started using Unity and am using GetAxis. I noticed when you move with the keyboard when you release the key the object doesnt immediately stop, it eases to a stop. Is there a way to make it stop immediately? I experimented with the sensitivity in the input settings but it still had the smoothing (ease-in, ease-out) behavior regardless of high or low sensitivity values. Thanks in advance for any help!
