Introduction to Physics
how physics is connected to other
disciplines like chemistry and
biology?
(a) Physics studies the properties
of matter and energy, which are
fundamental to all sciences.
(b) Physics focuses solely on
celestial bodies and space
exploration.
(c) Physics deals with the human
mind and cognitive processes.
(d) Physics has many application
in medical fi eld.
(v) Physics is the study of matter, energy
and the interaction existing between
them. What is the signifi cance of the
interaction of matter and energy in
physics?
(a) It helps us understand the human
body and its functions.
(b) It allows us to explore different
planets and their atmospheres.
(c) It helps explain the behaviour
of objects and phenomena in
the universe.
(d) It is not relevant to the study of
physics.
2. Outline the fundamental components
of the universe.
3. The operations of the universe lead
to a lot of phenomena like motion,
maintaining the shape of the earth,
light, heat and many more. The
vastness of these phenomena cannot
be covered within a single domain
of knowledge. Describe in brief, the
Physics Form 1 Final.indd 25
subfi eld (branches) that could cover
this vast knowledge.
4. Physics is the fundamental branch
of science as it provides tools for
learning other disciplines. The
following statements provide an
insight into how physics is connected
with other disciplines. Classify
the statements according to the
respective fi eld and suggest the set of
instruments designed using physics
theories and principles to assist the
working of other fi elds if any:
(a) exploration of the very far
objects in the sky.
(b) diagnosis of disease and
treatment of living organisms
(c) behaviour of atoms and
molecules, studying energy
changes during chemical
reactions.
(d) study of climate, weather
patterns, ocean currents, and
the behaviour of Earth’s crust.
(e) design and optimize
technologies, structures, and
systems

Basic steps of scientifi c procedures
5. In an experiment to investigate the
relationship between the angle of
a ramp and the distance a toy car
travels, students fi nd that the car
doesn’t move beyond a certain
point for steeper angles. What is the
problem that needs identifi cation in
