Physics is the branch of science that deals
with the study of matter, energy and the
mutual interactions between them. A person
who studies physics is known as a Physicist.
In Physics, matter is studied in relation to its
motion, as well as space and time. Matter is
defi ned as any substance which has mass and
occupies space. Physics as a subject uses concepts
like force, energy, and mass to explain different
phenomena. In doing so, students of physics get
to learn more about matter, energy and how they
interact with each other. Energy, for example, may
take the form of heat, light, or electricity. Among
the most important forms of energy today is
electricity which can be generated in many ways
including waterfalls and combustion of natural
gas. Figure 1.2 shows the power generation station
at Kinyerezi, Dar es Salaam.

Task 1.1
Identify and observe real-life examples of
physics concepts in your school and home
environments. Record your observations and
refl ect on how these examples illustrates the
concept learned in class.
