What are the classifications of physics?
0:03
Definition. The classifications of
0:05
physics are the major branches into
0:07
which physics is divided based on the
0:10
type of physical phenomena being
0:12
studied. Explanation. Physics is a broad
0:15
subject. So, it is grouped into
0:17
different branches to make the study
0:18
easier and more organized. Each branch
0:22
focuses on a particular aspect of nature
0:25
such as motion, heat, electricity,
0:27
light, or the structure of matter. These
0:30
classifications help students and
0:32
scientists study physical laws in a
0:35
systematic way. Imagine, think of
0:37
physics as a big tree. The trunk is
0:39
physics itself, while the branches
0:41
represent different areas like
0:43
mechanics, electricity, optics, and
0:46
modern physics. Each branch studies a
0:49
specific part of nature. In simple
0:51
terms, classifications of physics are
0:54
the different areas of physics. Each
0:56
studying a particular kind of physical
0:59
behavior. Formula. There is no single
1:02
formula for the classification of
1:04
physics. Each branch has its own laws
1:06
and formulas. Key points. Physics is
1:09
divided to simplify learning and
1:11
research. Each branch studies a specific
1:14
type of physical phenomenon. The
1:16
branches are closely related to one
1:18
another. Classical physics deals with
1:21
everyday phenomena. Modern physics deals
1:23
with atomic and subatomic phenomena.
1:26
Main classifications of physics.
1:28
Mechanics. Study of motion, force, work,
1:32
and energy. Thermal physics. Heat. Study
1:35
of heat, temperature, and energy
1:37
transfer. Waves and sound. Study of
1:40
vibrations and wave motion. Optics.
1:43
Light. Study of light and its behavior.
1:46
Electricity and magnetism. Study of
1:49
electric charges, currents and magnetic
1:52
fields. Atomic physics. Study of atoms
1:55
and their structure. Nuclear physics.
1:57
Study of the nucleus of atoms. Quantum
2:00
physics. Study of matter and energy at
2:03
very small scales. Relativity. Study of
2:06
space, time, and high-speed motion.
2:09
Examples. Motion of a car. Mechanics.
2:13
Heating water on a stove. Thermal
2:15
physics. Reflection in a mirror. Optics.
2:18
Electric fan working. Electricity.
2:21
Radioactive DK. Nuclear physics.
2:24
Applications. Vehicle and machine
2:26
design. Heating and cooling systems.
2:29
Lighting and optical devices. Power
2:32
generation and transmission. Medical
2:34
imaging and radiation therapy. Question.
2:38
Why is physics divided into different
2:40
branches? Answer. Physics is divided
2:43
into branches to make the study of
2:45
natural phenomena easier, more
2:47
organized, and more detailed. Solved
2:50
problem question. Which branch of
2:52
physics explains the motion of planets
2:55
around the sun? Answer. The motion of
2:57
planets around the sun is explained by
3:00
mechanics, specifically celestial
3:02
mechanics, which deals with the motion
