Rotational motion describes the movement made by an object that follows a circular path (which rotates) around an axis without moving on the axis.

Helical motion describes the movement performed by an object that follows a circular path (which rotates) around an axis while moving along the axis.

In short, helical motion is a fusion of rotational motion and rectilinear translational motion.

Also, helical motion and rotational motion are not represented by the same symbol.

• Helical movement is represented by the following symbol:

• Rotational movement is represented by the following symbols, depending on whether it is unidirectional or bidirectional:
