Question

Give two examples for each for the following motions :
(i) Linear motion
(ii) Spinning motion
(iii) Oscillatory motion
(iv) Periodic motion
(v) Vibrational motion
(vi) Circular motion
(vii) Random motion

Answer 1

Hint: In these types of motions object usually changes its position with time. Discuss the Characteristics of the types of Motions as given in the question and give the appropriate examples to better understand each type of motion.

Complete answer:
(i) Linear Motion - It is defined as the motion along a straight line. It is One Dimensional Motion.
Examples of Linear Motion –
Moving of a bicycle on the road.
Rolling of a ball.

(Ii) Spinning Motion - It is a motion of an object as it rotates around an axis through its centre of mass.
Examples of Spinning Motion-
Rotation of a fan.
Wheel of Sewing Machine.

(iii) Oscillatory Motion - It is defined as the repeated motion in which an object repeats the same movement again and again.
Examples of Oscillatory Motion-
The pendulum of a Clock.
Movement of a Swing.

(iv) Periodic Motion – It is defined as motion repeated in an equal interval of time.
Examples of Periodic Motion-
Movement of Earth around the Sun.
Water wave.

(v) Vibrational Motion – It is defined as the motion in which a part or parts of a body move to and fro in a definite pattern.
Examples of Vibrational Motion-
The string of a guitar.
The surface of Drum.

(vi) Circular Motion – It is defined as the movement of an object along a circular path.
Examples of Circular Motion-
Turning of Merry Go Round.
Bicycle Wheel.

(vii) Random Motion – It is defined as the motion in which a particle moves in a zig-zag manner and not in a straight path.
Examples of Random Motion-
Movement of Football Players.
Movement of Insects.

Note:
These all are the types of Motion which are discussed above and all of them have different characteristics. Motions of an object usually described in terms of distance, displacement, rate of change of velocity, speed, time, etc.
