Torque & Acceleration (Rotational Dynamics) definitions Flashcards

A measure of the force that can cause an object to rotate about an axis.

The rate of change of angular velocity, denoted as alpha.

The study of the effects of torques and angular acceleration on rotating bodies.

A measure of an object's resistance to changes in its rotation, analogous to mass in linear motion.

In rotational form, it states that the sum of all torques equals the moment of inertia times angular acceleration.

A rigid body with a specific moment of inertia, calculated as half the mass times the radius squared.

An object with mass concentrated at a single point, having no volume or shape.

The linear acceleration tangent to the circular path of a rotating object, related to angular acceleration.

An object with a fixed shape and size, where all points move in a fixed relationship to each other.

The sum of all torques acting on a body, determining its angular acceleration.

The distance from the center of rotation to the point where force is applied.

A trigonometric function used in torque calculations, representing the angle between force and radius.

A torque that causes rotation in the clockwise direction, often considered negative.

The unit of measurement for torque, equivalent to the force of one newton applied at a distance of one meter.

The study of forces and motion in a straight line, involving mass and linear acceleration.
