Angular Kinetics in Biomechanics

These flashcards cover key vocabulary terms related to the study of angular kinetics in biomechanics, helping with understanding rotating bodies and their motion.

Angular Momentum

The quantity of rotation of a body, which is the product of its moment of inertia and its angular velocity.

Moment of Inertia

A measure of an object's resistance to changes in its rotation rate, calculated as the sum of the mass of the object times the square of the distance from the axis of rotation.

Torque

A measure of the force that produces or tends to produce rotation or torsion.

Impulse-Momentum Relationship

The principle stating that the change in momentum of an object is equal to the impulse applied to it.

Angular Velocity

The rate of change of angular position of a rotating object, calculated in radians per second.

Radius of Gyration

A measure of how far from the axis of rotation the mass of a body is distributed, affecting its moment of inertia.

Equilibrium

A state in which all forces and torques acting on a body are balanced, resulting in no change in motion.

Counter-Rotation

The movement where a body part moves in the opposite direction to another, helping maintain balance and stability.

Angular Acceleration

The rate of change of angular velocity over time, typically measured in degrees or radians per second squared.

External Torque

The torque that is applied to an object from an outside force, affecting its angular motion.
