Answer 2

✴️️rotational motion occurs when an object rotates on its place.

✔️✔️Examples of Rotatory Motion:-

⭕️ Rotation of Earth on its axis
⭕️wind mill
⭕️spinning top
⭕️wheels of vehicle
⭕️ceiling fan.

➖Don't get confused between rotational and circular motion....➖

✴️rotational motion occurs when an object rotates 'on its place'

✴️circular motion occurs when an object moves 'in a circular path'

✔️✔Laws of rotational motion:-

⭕️First law:-
Everybody continues to be in the state of rest or of uniform motion in a straight line unless compelled by an external force to act otherwise.

⭕️Second law:-
The rate of change of momentum of a body is directly proportional tothe applied force and takes place in the direction in which the force acts.

⭕️Third law:-
To every action, there is always an equal and opposite reaction.
