Question

Paragraph 2: We can define motion as
the change of position of an object
with respect to time. A book falling
off a table, water flowing from the
tap, rattling windows, etc all exhibit
motion. Even the air that we breathe
exhibits motion! Everything in the
universe moves. We live in a universe
that is in continual motion. The
fundamental particle of a matter that
is the atom is in constant motion too.
Every physical process in the universe
is composed of motion of some sort.
The motion can either be swift or
slow, but motion exists. Motion is
mainly described in terms of
distance, displacement, speed and
time.We might have noticed that
different objects move differently.
Some objects move in a curved path,
some in a straight path and a few
others in a different way. According
to the nature of the movement,
motion is classified into different
categories. Q.1 Which of the following
can sometimes be 'zero' for a moving
body? i. Average velocity ii. Distance
travelled iii. Average speed in iv. displacement​
