Write one example for each of the following type of motion.
$(i)$. Rectilinear
$(ii)$. Circular
$(iii)$. Periodic
$(iv)$. Circular and periodic

$(i)$. Rectilinear- A car driving along a straight road is an example of rectilinear motion.

$(ii)$. Circular- The motion of the blades of the windmills is an example of circular motion.

$(iii)$. Periodic- A ticking clock or a bouncing ball is an example of periodic motion.

$(iv)$. Circular and periodic- Motion of blades in a rotating fan is an example of both circular and periodic motion.
