Document Summary
Chapter 3 principles of motion and stability: define, biomechanics. Ex: gravity, being in water, wind force: changes are predictable, based on optimizing principles of motion and stability. Ex: application and absorption of force, action and reaction, and stability and balance: can be seen across variety of motor skills, often produce more force, velocity, or accuracy, task, environment, and individual constraints interact. Similarities in constraints result in predictable change. What are some examples of similar constraints for individuals: environmental: gravity. Individual constraints: 2 arms, legs, upright posture: task constraint: equipment, desk. Impacted by growth, injury, etc: newton"s first law, an object at rest stays at rest and an object in motion stays in motion until acted upon by a force. To move something you must apply a force. Inertia is resistance to motion related to mass (inertial mass). More mass = greater resistance to motion, higher force must be applied to move object.
