Angular Kinematics

angular displacement

is the change in the angular position of an object, measured in radians, degrees, or revolutions. It signifies the angle through which a point or line has been rotated in a specified sense about a specific axis.

clockwise

negative

counterclockwise

positive

average angular velocity

is the rate of change of angular displacement over time, expressed in (rad/s). It indicates how quickly an object rotates around an axis.

tangenital velocity

is the linear velocity of an object moving along a circular path, directed tangent to the circle at that point, and measured in meters per second (m/s).

angular acceleration

is the rate of change of angular velocity over time, measured in (rad/s²). It indicates how quickly an object's rotational speed is changing.

tangenital acceleration

is the rate of change of tangential velocity over time, measured in (m/s²). It indicates how quickly the speed of an object moving along a circular path is changing.

centripetal acceleration

is the acceleration directed towards the center of the circular path, keeping an object in circular motion, measured in (m/s²).
