There are different types of Motion, but all of them are categorized under either linear motion or rotational motion.

linear motion : If all the particles of a moving rigid body travel in a straight line and cover the same distance within a fixed time, the motion is called linear motion.

Let us take a particular case when, after some time a rigid body moves from one location to another. Suppose, three particles of the body change their position from x, y, z to x1, y1, z1 respectively and the distance between the x to x1, y to y1 and z to z1 are equal. Now, if we connect x to x1, y to y1 and z to z1 then xx1, yy1, zz1 become parallel. This type of motion is called as linear motion. rotational motion : If all the particles of a moving rigid body travel in a circular path in a fixed axis, the motion is known as rotational motion. Note: wheel of a running car is a classic example of linear motion, as well as rotational motion.
