key term - Rotational Velocity

Definition

Rotational velocity refers to the rate at which an object rotates, measured in units of radians per second (rad/s). It represents how quickly an object is spinning around a fixed axis.

Related terms

Angular Velocity:

Angular velocity is another term used to describe rotational motion. It measures how quickly an object is rotating around an axis, but it's measured in units of degrees per second (°/s) rather than radians per second.

Tangential Velocity:

Tangential velocity refers to the linear speed of an object moving along its circular path. It represents how fast an object is moving tangent to its circular trajectory.

Centripetal Acceleration:

Centripetal acceleration describes the inward acceleration experienced by an object moving in a circular path. It is always directed towards the center of the circle and allows objects to maintain their curved trajectories.
