Key Concepts

Angular Speed

Angular speed is a measure of the rate at which an object rotates or moves along a circular path. It is calculated by dividing the linear speed by the radius of the circular path, and it describes how quickly the angle in radians changes per unit time.

Radial (Centripetal) Acceleration

Radial acceleration, often called centripetal acceleration, is the acceleration directed toward the center of a circular path. It is responsible for changing the direction of the velocity vector and is calculated using the formula v²/r, where v is the linear speed and r is the radius of the circular path.

Tangential Acceleration

Tangential acceleration refers to the rate at which the speed of an object moving along a curved path changes with time. It acts along the direction of the velocity and, in cases where the speed is constant, the tangential acceleration is zero.
