Dynamics

Definition

Dynamics refers to the study of forces and motion within systems, particularly how these elements interact over time. In the context of biological systems, dynamics play a crucial role in understanding how various components behave and respond to stimuli, which is essential for modeling and predicting system behaviors through transfer functions. This understanding allows bioengineers to design and analyze systems that mimic or interact with biological processes effectively.
