Angular Kinetics | Kin2040 Introduction to Biomechanics

These flashcards cover key concepts related to angular kinetics, including definitions and relationships between different terms in biomechanics.

Angular Kinetics

The angular version of Newton's laws of motion.

Angular Inertia

The property of an object to resist changes in its angular motion, quantified as moment of inertia.

Linear inertia

The resistance of an object to changes in its linear motion, dependent on its mass.

Moment of Inertia

A measure of an object's resistance to angular acceleration, dependent on the mass distribution relative to the axis of rotation.

Radius of Gyration (k)

A length measurement representing how far from the axis of rotation all of the object's mass must be concentrated.

Eccentric Axis

An axis that does not pass through the implement's center of gravity.

Linear momentum

The quantity of motion of an object, calculated as the product of mass and velocity.

Angular Momentum

The angular analog of linear momentum, defined as the product of the moment of inertia and angular velocity.

Newton's laws of motion

Principles that describe the motion of objects, which can be applied in an angular context for rotational dynamics.

Mass

A measure of the amount of matter in an object, which affects both linear and angular inertia.

Angular Velocity

The rate of change of angular displacement, usually measured in radians per second.
