Whirling motion is a type of motion that involves rapid circular or rotational movement. The term can be used to describe the motion of objects in the air, such as a tornado, or the motion of objects in water, such as a whirlpool. Two words that can be used to describe this type of motion are VORTEX (6 letters) and SPIN (4 letters). VORTEX refers to a mass of rotating air or water, while SPIN refers to the act of rotating rapidly.
