Dynamics is the branch of classical mechanics that is concerned with the study of forces and their effects on motion. Isaac Newton was the first to formulate the fundamental physical laws that govern dynamics in classical non-relativistic physics, especially his second law of motion. Each of one piece is developed in a form to be part of an invisible game at the end of the collection. Each piece is created to be part of an invisible game at the end of the entire collection. 10 series of 10 pieces each. A representative color for each series.
