Motion - It is the change of position of object with respect to time.
It has following types -
1. Translatory motion - Object moves along a straight line.
Motion of car,bus etc.
Motion of car,bus etc.
2. Rotational motion - Object moves around any fix axis. And that fix axis is known as axis of rotation.
Motion of object in a circular path. Radius of that circle is axis of rotation or rotational axis.
Motion of object in a circular path. Radius of that circle is axis of rotation or rotational axis.
3. Oscillatory motion - Object moves up-down, left-right, to-fro of its mean position.
Motion of loaded spring, to make swing, pendulum etc.
Motion of loaded spring, to make swing, pendulum etc.
Note- In the absence of any external force object is placed at a position which is known as mean position.
Example.-When cell of clock is taken out then its pendulum is in rest at a position. which is mean position.

Types of motion on the basis of dimensions.
It has following types -
1. One dimensional motion - Object moving along a particular axis(x, y or z).
Motion of car bus, human.
2. Two dimensional motion - Object moving in a plane (xy, yz, zx).
Motion of a fly.

3. Three dimensional motion - Object moving in free space.
Motion of Bird, Airplane etc
