Please state whether the statement below is true or false. If true or false, please explain why.
The motion of the spring which is oscillatory has a positive velocity when the spring expands and a negative velocity when the spring contracts. Thus the negative value of the velocity can only be taken care of by the absolute value of dx/dt, i.e. |dx/dt|. Therefore the damping term which oscillates between positive and negative values is better represented by ?|dx/dt|dx/dt instead of ?(dx/dt)2.
