Newton`s 2nd Law, friction
... Mechanics is the branch of physics that deals with the analysis of motion and its causes. Specifically, kinematics is the descriptive branch of mechanics, and dynamics is the causal. Newton's second law relates the net sum of vector forces that are dynamical to the acceleration of an object. In this ...

... In order for the damping ratio δ to be less than zero, that is, to be negative, we would have to have the opposite of damping, something that puts energy into the system instead of taking it out. As the energy is added to the system the amplitude grows and grows. The energy is added by an outside so ...
