Question

6. What is rotational motion? Give two examples.
​

Answer 1

When an object moves in a straight line then the motion is considered as translational but when the same object moves along an axis in a circular path then it is known as Rotational Motion. Consider a wheel rolling without slipping in a straight line.

Similarly, earth rotates at its own axis and also rotates around Sun in another orbit. Rotation of worm driver over worm gear is another example. A person performing a Somersault, is an example of rotational motion. Fan moving in the house, table fan, hand blender's blades motion are all examples of rotational motion.
