Term
 biology
Definition
 Science dealing with origin, form, and behaviour of living things.
Term
 Mechanics
Definition
 Branch of physics that describes motion and how forces create motion. Science that studies the influence of forces on bodies.
Term
 biomechanics
Definition
 The study of mechanics applied to biology. Descrive the influence of forces on biological systems such as humans, animals, plants, organs, and cells using methods of mechanics.
Term
Definition
 1. mobility of a person 2. work-related injury 3. reducing osteoporosis 4. understanding the effects of microgravity 5. improving the performance of an athlete 6. designing saver vehicles

Definition
 "study of bodies in motion"   Objects subjected to acceleration, or a change in the state of motion.
Term
 kinematics
Definition
 The description of motion without regard to its causes.
Term
 Kinetics
Definition
 The study the causes of motion (primarily the study of forces)   force, moment, work, impulse, power, etc.
Term
