18 Rotational Dynamics

Flashcards focused on key vocabulary terms related to rotational dynamics as covered in the lecture.

Equilibrium

A state where an object experiences no net force and no net torque.

Angular Momentum

Momentum associated with an object's rotational motion, calculated as L = Iω.

Conservation of Angular Momentum

The principle stating that the total angular momentum of a system remains constant if no external torques act on it.

Rotational Kinetic Energy

The energy an object possesses due to its rotation, typically expressed as (1/2)Iω².

Net Torque

The total torque acting on an object, influencing its angular acceleration.

Moment of Inertia

A measure of an object's resistance to changes in its rotation, dependent on mass distribution.

Angular Velocity (ω)

The rate of rotation of an object, expressed in radians per second.

Newton’s Second Law for Rotational Motion

States that net torque (τnet) is equal to moment of inertia multiplied by angular acceleration (α).

Translational Speed

The speed at which an object moves along a path, distinct from its rotational speed.
