What is physics? Definition: Physics is
0:03
the branch of science that studies
0:05
matter, energy, motion, force, space,
0:08
and time, and how they interact with one
0:11
another. Explanation: Physics seeks to
0:14
understand how the universe works from
0:16
the smallest particles like atoms to the
0:18
largest objects like stars and galaxies.
0:22
It explains natural phenomena using
0:25
observations, experiments, measurements,
0:27
and mathematical laws.
0:30
Through physics, we learn why objects
0:32
fall, how electricity flows, how light
0:35
travels, and how machines work. Imagine.
0:39
Imagine throwing a ball. Why does it
0:41
move forward? Why does it slow down and
0:44
fall back to the ground? Physics
0:46
explains the motion of the ball, the
0:48
force from your hand, the pull of
0:50
gravity, and the resistance of air. In
0:53
simple terms, physics helps us
0:55
understand how and why things happen in
0:57
the natural world. formula. Physics does
1:00
not have one single formula. Instead, it
1:03
uses many formulas to describe different
1:06
physical situations such as motion,
1:09
force, energy, heat, electricity, and
1:12
waves. Key points: Physics deals with
1:15
matter and energy. It explains natural
1:18
laws governing the universe. It uses
1:20
experiments and mathematics. Physics
1:23
forms the foundation of other sciences.
1:26
It helps in understanding technology and
1:28
modern inventions. Examples motion of
1:31
cars on the road. Fulling objects due to
1:34
gravity. Flow of electric current in
1:37
wires. Reflection of light in mirrors.
1:40
Sound produced by musical instruments.
1:42
Applications. Transportation and vehicle
1:45
design. Electricity and power
1:48
generation. Electronics and
1:50
communication devices. medical equipment
1:53
like X-ray and MRI, space exploration
1:57
and satellite technology. Question, why
2:00
is physics important in everyday life?
2:03
Answer: Physics is important because it
2:05
helps us understand natural phenomena
2:08
and provides the principles behind
2:10
modern technology used in daily life.
2:13
Solved problem question. A ball is
2:16
thrown vertically upward and then falls
2:18
back to the ground. Which branch of
2:21
physics explains this motion? Answer.
2:24
The motion of the ball is explained by
2:26
mechanics, a branch of physics that
2:28
deals with motion and forces.
