Angular Kinematics

These flashcards cover key terms and concepts related to Angular Kinematics, focusing on definitions that will aid in understanding angular motion and its applications.

Angular Kinematics

The study of angular motion, focusing on how different parts of a body move through the same angle.

Absolute Angle

The angle of inclination of a body segment relative to a fixed reference in the environment.

Relative Angle

The angle between the longitudinal axes of two segments, often related to joint angles.

Degrees

A unit of measurement for angles; most commonly used, where 90° indicates perpendicular sides.

Radians

A unit of angular measure; the angle at the center of a circle that subtends an arc equal to the radius of the circle.

Joint Angle

An angle formed between two body segments at a joint.

Flexion

A movement that decreases the angle between two body parts, typically at a joint.

Extension

A movement that increases the angle between two body parts, typically at a joint.

Right-Hand Rule

A convention used to determine the direction of a positive angular motion vector.

Quadrants

Divisions of the Cartesian plane that determine the position of angles based on their x and y values.

Tanθ

A trigonometric function used to calculate the angle based on the ratio of the opposite side to the adjacent side in a right triangle.

Angular Motion

Movement of the entire body about an axis, with all points moving through the same angle.

General Motion

A combination of segmental rotation (angular motion) and linear motion (translation).
