1.Momentum –product of motion, measured as the product of a body mass and its velocity.
2.Impulse-Product of a force and the time interval over which the force acts.
3.Distal-the point furthest from the point of attachment to the body.
4.Plantar flexion-the movement that increases the approximate 90-degree angle between
the front part of the foot and the shin, as when depressing an automobile pedal
5.Balance-Ability to control equilibrium
6.Posterior -Further back in position of or nearer the rear or hind end.
7.Flexion-the joint angle decreasing
8.Extension-movement of a joint whereby one part of the body is moved away from another
9.Trajectory –the flight or path of a projectile
10.Velocity-measurement of the rate and direction of change in position of an object
11.Bending-asymmetric loading that produces tension on one side of a body’s
longitudinal axis and compression on the other side.
12.Acceleration -the rate of change of velocity over time
13.Potential energy-energy by virtue of a body’s position of configuration, calculated as the product of weight and height.
14.Type 2A Muscle fibers-Fast twitch muscle fibers
15.Combined loading-simultaneous action of more then one form of loading.
16.Axis of rotation-imaginary line perpendicular to the plane of rotation and passing through the center of rotation
17.Magnus force-lift force created by spin
18.Stress –distribution of force within a body, quantified by force divided by the area in which the force acts.
19.Static Equilibrium-a motionless state
