Differentiation of a noisy analog signal

[Sully1071]

I am using Usb 6008 to acquire an analogue signal from a string potentiometer, i am differentiating this signal to find velocity and again to find acceleration. When doing this the noise is amplifying..

Is there any easy filter to implement that will rid or at least reduce?

Any help is appreciated.
