What is Physics? What is it all about?

Question

I don't mean to sound ignorant, but from this September, I'll be studying Physics, and this would be our first time.

I really don't know what it is about and I don't have any books.

I know it has got to do something with Mathematics, but not sure what it is exactly about.

Could you please explain the basics of the subject, and what it is all about?

I want to know what I'm gonna learn.

How difficult is it by the way?

Please rate the difficulty (your opinion) from 1 to 5

Thanks.

<:^_^:>

Have a Good Day!

Answer 1

Physics is the application of math to physical processes. In high school physics you&#039;ll mostly be dealing with the motion and energy of objects. For example you&#039;ll be finding out how fast a car is going if it&#039;s been accelerating for a certain period of time. You may also deal with the properties of light and waves as well as touch on modern physics such as the photoelectric effect and black bodies.

As far as difficulty goes, that depends on you. I would give high school physics a 2 on your scale. However, many people find it a 5. If you are someone who likes math and can think in a logical manner you&#039;ll do fine.

The biggest tip I can give to you is DO NOT TRY TO MEMORIZE. The people who think they can memorize how to do every specific problem are the ones who fail. Instead, you need to learn the processes and learn how to think your way out of a problem. Instead of memorizing individual problems you should build yourself a &quot;toolbox&quot; of methods to help you solve any problem.

Answer 2

Physics is about learning things that other people made up to explain things that normally cant be explain...

hehehehehhee

It&#039;s 1 to me. It&#039;s kinda easy.

Answer 3

Difficulty = 5

Physics is the study of the physical properties of the universe such as Light, Gravity, and Matter.

Answer 4

In the most broad of terms, physics is the study of how the physical world behaves.  Not people (that&#039;s psychology and anthropology) or animals (biology), but the things and objects in the world.  You will probably study the following:

* How things move or why they don&#039;t move (forces, momentum, friction, energy, work, etc.)

* How electricity and magnetism work (motors, circuits, magnetic poles and attractions, etc.)

* Basic fluid principles (buoyancy, hydrostatics, pressure, etc.)

Mathematics is not part of physics, but it&#039;s a key tool of physics.  Early physics courses use basic math to compute results of experiments and manipulate given equations of physics, so you&#039;ll need algebra.  More advanced high school level physics gets into deriving basic equations of motion and more advanced manipulation of systems of physics equations, so you&#039;ll need to be enrolled in calculus and probably have pre-calculus behind you.  In college, physics is generally taught using calculus to describe the physics principles, so you&#039;ll need good calculus skills.  Advanced physics deals with motion of objects at high speed (Einstein&#039;s equations, for example), and subatomic particle motion (quantum physics), and relies heavily on an advanced calculus sequence called differential equations.  But that&#039;s not something you&#039;ll need to worry about until senior year of a physics or engineering program at college, or graduate school.

In terms of difficulty at a high school level, physics is probably the hardest course you&#039;ll take.  AP Physics is about as hard as it gets in high school, in terms of grasping concepts and using other skills (like advanced math).  But it&#039;s also incredibly interesting, and you&#039;ll learn a lot about the world.  If you intend to go on to college for ANY science program (engineering, science teacher, physicist, chemist, biologist, or mathematician), take as much physics in high school as you can.  It gets 10x harder in college, when they start using calculus a lot and the pace of learning increases, so best to get a good introduction while you&#039;re in high school even if it means a couple extra hours of homework a week.

Good luck!

Here is the link to the website:

I would rate physics a 2 from 1 to 5.

Physics is the science of matter[1] and its motion,[2][3] as well as space and time.[4][5] It uses concepts such as energy, force, mass, and charge. Physics is an experimental science,[6] creating theories that are tested against observations. Broadly, it is the general scientific analysis of nature, with a goal of understanding how the universe behaves.[7]

Physics is one of the oldest academic disciplines, and through its modern subfield of astronomy, it may be the oldest of all.[8] Experimental physics began in the Middle Ages and eventually emerged as a modern science during the early modern period.[9] Those who work professionally in the field are known as physicists.

Advances in physics often translate to the technological sector, and sometimes influence the other sciences, as well as mathematics and philosophy. For example, advances in the understanding of electromagnetism have led to the widespread use of electrically driven devices (televisions, computers, home appliances etc.); advances in thermodynamics led to the development of motorized transport; and advances in mechanics motivated and benefitted from the development of calculus, quantum chemistry, and the use of instruments such as the electron microscope in microbiology. The &quot;Atomic Age&quot; is also an important concept in philosophy and historical analysis.

Today, physics is a broad and highly developed subject. Research is often divided into four subfields: condensed matter physics; atomic, molecular, and optical physics; high-energy physics; and astronomy and astrophysics. Most physicists also specialize in either theoretical or experimental research, the former dealing with the development of new theories, and the latter dealing with the experimental testing of theories and the discovery of new phenomena. Despite important discoveries during the last four centuries, there are a number of unsolved problems in physics, and many areas of active research.

Answer 6

Physics is the study of motion. Since everything that happens involves motion, then by extension, physics is the study of everything.

SC is wrong: physics is perfectly applicable to the study of humans and animals. Everything a human or animal does is in accordance with and due to the laws of physics that also hold for everything else in the universe.

hipp5 is wrong: physics need not involve the application of mathematics to anything, although in practical terms, we nearly always do use it. Mathematics is certainly not the central nature of physics; it is merely a tool that we use to arrive at quantitative preditions. Central to physics are the concepts of motion, energy, etc., not the math.
