Horizontal Abduction.

What is the position of the hands when standing in the anatomical position?

Supination.

What are the Cardinal Planes that intersect at the body's CG in the anatomical position?

Transverse, Sagital, Frontal.

What is an Angle or Angular Displacement?

A measure that is the same for any point along the radius during an arm curl.

What kinematic measure increases as a diver rotates towards the water?

Linear Momentum.

What creates Angular Acceleration on rotating bodies and objects?

Torque.

How does Angular Displacement relate to Angular Velocity?

Angular Displacement relates to Angular Velocity as Angular Distance relates to Angular Speed.

57.3 degrees.

What two measures determine a given arc length?

The Radius and Angle.

What is an Arc Length?

The linear distance traveled when running in a circle.

What are Radians?

A unitless angular measure.

How many Radians does a wheel travel during 1.75 revolutions?

10.99 radians.

What is the negative direction when objects rotate?

Clockwise.

What is the most important linear outcome in striking, throwing, kicking or jumping?

Linear Velocity.

What is a Linear (tangent) Path?

The direction a stone takes if it breaks away from a rotating rope.

What keeps a lasso rotating overhead in a circle?

Centripetal Force.

What two linear accelerations does a hammer thrower create when rotating in a circle?

Tangential and Radial Accelerations.

What type of centripetal force allows a cyclist to stay on a curved path?

Frictional Force.

What stays constant as you move your arms in & out while spinning?

Angular Momentum.

What decreases for a quicker recovery stroke when a swimmer flexes the elbow overhead?

Moment of Inertia.

What is the Radius of Gyration?

It averages the distance of all mass particles from the axis of rotation.

What are the two factors that comprise Moment of Inertia?

Mass and Radius of Gyration.

What is the plane of motion and its axis in a golf swing?

Transverse Plane around its Longitudinal Axis.

What unique conical movement is capable at the shoulder and hip joints?

Circumduction.

What produces a change in an object's Angular Momentum?

Angular Impulse.

What is Zero Angular Acceleration?

The magnitude of a rotating object's angular acceleration when its angular velocity stays constant.

What creates an Angular Impulse to an object?

The product of Torque and Time.
