न्यूटन के श्यानता के नियम के अनुसार, अपरूपण प्रतिबल, कोणीय विरूपण (अपरूपण प्रतिबल) या वेग प्रवणता की दर के सीधे आनुपातिक है।
जहां, τ = अपरूपण प्रतिबल, μ = पूर्ण या गतिविधिक श्यानता, du/dy = वेग प्रवणता ⇒ dα/dt = कोणीय विरूपण की दर (अपरूपण-विकृति)
गतिविधिक श्यानता की इकाइयाँ:
∴ SI इकाई में गतिविधिक श्यानता की इकाई Ns/m2 या Pa-s है।
