Explain the types of motion with example |
|
Answer» Solution :(a) Linear motion: An OBJECT is said to be in linear motion of it moves in a straight line. Examples: An athlete running on a straight track A particle falling vertically downwards to the Earth. (b)Circular motion: Circular motion is defined as a motion described by an obiet traversing a circular path Examples: The whirling motion of a stone attached to a string. The motion of a satellite around the Earth. These two circular MOTIONS are shown in figure.  (c) Rotational motion: If any object moves in a rotational motion about an axis, the motio is called .rotation. During rotation EVERY point in the object transverses a circular path about an axis. (except the points located on the axis). Examples: otation of a disc about an axis through its CENTER Spinning of the Earth about its own axis. These two rotational motions are shown in figure.  (d) Vibratory motion: If an object or particle executes a to and fro motion about a fixed point, it is said to be in vibratory motion. This is sometimes ALSO called oscillatory motion. Examples Vibration of a string on a guitar Movement of a swing These motions are shown in figure  Other types of motion like elliptical motion and helical motion are also possible. |
