TOPIC 1: INTRODUCTION TO PHYSICS | PHYSICS FORM 1
Physics is often described as the study of matter and energy. It is concerned with how matter and energy relate to each other, and how they affect each other over time and through space. Physicists ask the fundamental questions how did the universe begin? how and of what is it made? how does it change? what rules govern its behavior?
The Concepts of Physics
Explain the concepts of physics
Physics is described as the general scientific study of nature that aims to understand the behavior of the universe.
Physics, therefore tries to explain how things happen around us or why
they happen the way they do. For example, how a car moves from one point
to another? Why unlike poles of magnets attract? Why does a mango fall?
How is a rainbow formed? And so on.
as a subject uses concepts like force, energy, mass, power among others
to explain different phenomena. Energy, for example, may take the form
of motion, light or electricity. In so doing, students of Physics get to
learn more about matter and energy and how they interact with each
Therefore, Physics is the study of the relationship between matter and energy.
The people who study and work professionally in this field are called physicists.
is an experimental science subject, which creates theories that are
tested against observations of the natural world. Theories are used to
explain why things behave the way they do. This is why physicists always
insist on accurate measurements and a record of results during each experiment.
these results are in precise mathematical forms, technologists make use
of such data when designing devices such as radios, televisions, mobile
phones, computers, and artificial satellites. All these things are for
the betterment of human life.
The Relationship between Physics and other Subjects
Establish the relationship between physics and other subjects
of physics is also applied in other subjects. The principles of
electrostatics and particulate nature, for example, are used to explain
reactions in chemistry. The tools, implements and farm machinery learnt
in agriculture as well as the process of dating historical remains are
applications of physics.
provides the basis for biology. Without space, matter, energy and time
— components that make up the universe — living organisms would not
exist. Physicist Richard Feynman said that everything on earth is made
of atoms, basic units of matter, that constantly move. Since biology has
its foundation in physics, it applies physical natural laws to the
study of living organisms, according to Muskegon Community College. For
instance, physics helps explain how bats use sound waves to navigate in
the dark and how wings give insects the ability to move through the air.
The American Physical Society shares that many flowers arrange their
seeds or petals in a Fibonacci-like sequence to maximize exposure to
light and nutrients. In some cases, biology helps prove physical laws
and theories. Feynman states that biology helped scientists come up with
the law of conservation of energy.
