There are three types of motion:
In translatory motion the particle moves from one point in space to another. This motion may be along a straight line or along a curved path. The motion along a straight line is called rectilinear motion.
Example: A car moving on a straight road
Motion along a curved path is called curvilinear motion.
Example: A car negotiating a curve
In rotatory motion, the particles of the body describe concentric circles about the axis of motion.
Rotatory motion
In vibratory motion the particles move to and fro about a fixed point.
Simple pendulum
