Rotational Motion
A rotational motion, also known as rotatory motion, is a type of motion in which all points of a rigid body maintain a constant distance from an imaginary axis and rotate in circular paths about a common axis with a common velocity. An object can undergo translational and rotational motion at the same time.
Examples
- Earth rotating about its axis
- Subatomic particles rotating in a cyclotron
- A skater exhibiting rotation during her routine
- A wheel rolling down a hill
- A football spinning in its trajectory
- A phonograph’s turntable rotating about a pin
- A potter’s wheel rotating about its center
