In class today, my professor said that you will never find a force that is a function of acceleration.(adsbygoogle = window.adsbygoogle || []).push({});

Why is this?

M[tex]\ddot{x}[/tex](t) = F(x,y,z,[tex]\dot{x},\dot{y},\dot{z}[/tex],t)

M[tex]\ddot{y}[/tex](t) = F(x,y,z,[tex]\dot{x},\dot{y},\dot{z}[/tex],t)

M[tex]\ddot{z}[/tex](t) = F(x,y,z,[tex]\dot{x},\dot{y},\dot{z}[/tex],t)

This is in a classical mechanics / dynamics course
