Document Summary
Major two branches of mechanics: statics- interested in unchanging systems. Loads and responses to loads, often used in material science. In a biomechanics setting, they are referred to as tissue mechanics : dynamics- interested in changing systems. Further subdivisions of dynamics: kinematics- study of motion w/o consideration of the cause, kinetics- study of actions of forces that cause the motion. Kinematics- the study of motion without considering what is causing the motion. Body: the object of analysis; it could be a whole person, a part of a person, or an inanimate object. System: the object of analysis that is made up of two or more bodies. Point: a way of representing a body that has no dimensions. Frame of reference: the perspective from which the movement is described ex) school is located 5 miles away from home. Origin: the place where the frame of reference begins. Direction: a pointing toward something, determined by its orientation and sense.
