Change of angle per unit time, measured in radians

A point representing the mean position of the matter in a body or system

The apparent acceleration, equal in magnitude and opposite in directions to the centripetal acceleration, drawing a rotating body away from the center of rotation, caused by the inertia of the body

An apparent force that acts outward on a body moving around a center, arising from the body's inertia

A force that acts on a body moving in a circular path and is directed toward the center around which the body is moving

The acceleration toward the center of rotation that holds an object in its circular motion

The force of attraction between all masses in the universe

A quantity expressing a body's tendency to resist angular acceleration

The ratio of the arc length to the radius of the curve. Radian describes the angle subtended by circular arc as the length of the arc divided by the radius. A radian describes the unit of angle, equal to an angle at the center of a circle whose arc is equal in length to the radius

The action of forces and torques on rigid objects as they rotate

Angular kinetic energy, kinetic energy due to the rotation of an object and is part of its total kinetic energy

Rotation around a fixed axis

Acceleration is the rate of change of velocity over time with a direction that is tangent to the curve

The speed of an object that is tangent to the object's circular path

A twisting force that tends to cause rotation

The universal constant relating force to mass and distance in Newton's law of gravitation
