- Cognitive
- The learner is endeavoring to understand the nature and/ or goal of the activity to be learned.
- Dynamography
- Technique used to measure the forces produced during a movement.
- Body Composition
- Description of the body in terms of muscle, bone, fat, and other elements.
- Autonomous
- Reached after much practice. The learner can perform the skill consistently with few errors. The skill has become almost automatic.

- The application fo scientific principles of mechanics to understand movements and actions of human bodies and sport implements.
- Lever
- Mechanical device used to produce a turning motion about a fixed point, called and AXIS.
- Ergogenic Aids
- Work-producing substances or phenomena believed to increase perfomance.
- 3rd-class lever
- The force is between the fulcrum and weight.
- Physical Fitness
- Ability of the body's systems to function efficiently and effectively.
- Motivation
- A condition within an individual that initiates activity directed toward a goal.
- Motor Learning
- The study of the acquisition of motor skills as a result of practice and experience.
- Newtons First law
- The law of inertia states that a body at rest will remain at rest and a body in motion will remain in motion at the same speed and in the same directin unless acted on by some outside force.
- Gravity
- Force that accelerates all objects vertically toward the center of the earth.
- Kinetics
- Study of forces that act on a system, such as gracity and muscles
- Weight or resistance arm
- The distance from the fulcrum to the wieght on which the force is acting
- Newton's Second Law
- The law of acceleration states that a change in velocity (acceleration) of an object is directly proportional to the force producing it and inversely proportional to its mass.
- Mass
- Amount of matter possessed by an object.
- Nonlocomotor(Axial Movements)
- Done from relativly stationary postion, using a stable base of support.
- Statics
- The study of factors relating to nonmoving systems such as studying factors the contribute to stability and balance.

- Handling objects;throwing, catching, striking, and kicking are examples.
- Electromygraphy
- Used to measure the electrical activity produced by a muscle or muscle group.
- Feedback
- Information about the performance of the movement and its quality, the appropriateness, and/or outcome. This information can be used to proved input for making ongoing adjustments in performance or to modify the next skill attempt.
- Force Arm
- The distance from the fulcrum to the point of application of force
- Anthropometry
- Concerned with measurement of the human body.
- Telemetry
- Involves the wireless recording of varous aspects of movement.

- Acceleration
- Change of velocity
- Electrogoniometry
- Technique that can be used to provide information about the angles of join as part of total motion pattern.
- Associative
- The basics of the skill have been learned and the learner concentrates on refining the skill.
- Newton's Third Law
- The law of action and reaction states that for evry action there is an equal and opposite reaction.
- Stroboscopy
- An older photographics technique that can still be used today to study human movement.
- Power
- Amount of work accomplished in one unit of time
- Velocity
- Change in the speed and/or direction of a body per unit of time.
- Pressure
- Ratio of force to the area over which the force applied
- 1st-class lever
