Definitions

• Modeling A schematic description of a system,
  theory, or phenomenon that accounts for its known
  or inferred properties Drawings, 3D models
• Simulation Predict aspects of the behavior of a
  system by creating a mathematical model including
  reactions and interactions
• Kinematics The branch of mechanics that studies
  the motion of a body or a system of bodies
  without consideration given to its mass or the
  forces acting on it motion without interactions
• Dynamics The branch of mechanics that covers the
  effects of forces on the motion of a body or
  system of bodies, especially of forces that do
  not originate within the system itself motion
  with impacts and interactions
• ADAMS Automatic Dynamic Analysis of Mechanical
  Systems. Systems-based kinematic and dynamic
  analysis tool
