How long to study physics?

Physics degree entry requirements – To study physics at university, it is likely that you’ll be required to have completed secondary-level qualifications (such as A-levels) in both physics and mathematics. An advanced mathematics qualification (such as ‘further’ or ‘higher’ mathematics) and an additional science, such as chemistry, may also aid your application.

  1. Those who study physics will graduate in three or four years with a Bachelor of Science (BSc).
  2. Some universities offer the option to continue studying for an additional one or two years, graduating with a Master of Physics (MPhys) or a Master of Science (MSci).
  3. Alternatively a separate master’s program may be applied for after completing the bachelor’s degree.

How hard is physics 12?

You know the old, “If I had a nickel” line? For instances like this, I wish it could come true, because if I had a nickel for every time someone asked me about grade 12 physics, I’m sure I could’ve paid my way through first-year university. Physics is notorious for being one of the more difficult courses in high school, and tends to be the first course that gets dropped when grade 12 rolls around.

  • The question of “should I take physics?” is the most frequent question I get asked, especially being someone who chose to pursue the life sciences.
  • So the question is: should you take grade 12 physics? Let’s start from the beginning.
  • Room (I mean list) of Requirements Before you go making any choices about taking/dropping any course, it’s important to look at the programs you’re applying to, and see what they’re looking for.

If you’re planning to go into an engineering, computer science, or physical sciences stream, most often physics is on the required list of courses. So, if you’re even considering entering one of those streams, physics is a must-have. This was one of the reasons I continued to take it: I’d applied to pursue both engineering and life science, so if I ended up wanting to become an engineer, I would’ve needed that course.

  • Another thing to consider (and one that can be overlooked by life science applicants) are the required courses for your first-year classes.
  • It’s possible that a first-year physics class may require grade 12 physics, and missing that credit would require you to make it up in university.
  • Often, universities will offer grade 12 equivalencies if you’re missing the credit, but taking those in first year can often make you feel like you’re being left behind.

So, make sure you check the course requirements — yes, even for life science — to see if you need it. If you don’t take 12U, at LEAST take 11U Okay, so you’ve checked your course requirements, and you’ve found that physics isn’t on the list. Huzzah! However, this doesn’t mean you can opt to take zero physics courses altogether.

Most of the time, grade 11 physics is a requirement for the physics classes in first-year, and not taking it can put you in a hard place. Again, having to make-up for high school courses in university can be challenging, since it means finishing up your required course list later in the year (and having less space for electives).

If you can, I highly recommend that you at least take grade 11 physics, even if it means taking it in grade 12. It makes your life so much easier. But honestly, there are actual reasons to take physics in high school. Physics is pretty cool! I’m a bit of an outlier when it comes to my love of physics.

While it may not seem like it, physics is one of my favourite topics. One of my passions is understanding how things work, and physics is one of the biggest ways you can do that. Fun story: we’d learned about coaxial cables in grade 12 physics, which are used in cords and wiring to ensure the fields generated from the current running through the wire (like in a laptop charger) don’t interfere with the technology surrounding it.

Driven by my curiosity, when I went to visit my friend at U of T, I made an interesting first impression on her roommate as I proceeded to excitedly strip the rubber away from her broken MacBook charger and look at the structure of the coaxial cable (I asked first, don’t worry).

Case and point, she may have thought I was the biggest- and weirdest- nerd on the whole planet, but to me, all that mattered was the fact that I got to see the physics theory I’d learned be put into practice. To me, that’s the coolest thing about physics: it really is a science that’s applicable (at least on the high school level) to everything that goes on around you.

You have the ability to break something down and fully understand it for what it is. Why things happen isn’t a mystery, but a puzzle that can be solved with known concepts and theories. Even the smallest things can change your world view: when I first learned about forces and free-body diagrams in grade 11, I was in shock for at least a week! The science behind everything, from rainbows to springs, can put a lot of the real world into a scientific context.

Isn’t it cool when things make sense? Learning the hard life lessons However, while physics is one of my favourite subjects, I’ll openly admit it was one of my least favourite subjects to be evaluated on (I only began to truly appreciate physics AFTER high school). While I was going through it, I definitely didn’t have the ideal classroom experience (this can vary depending on your instructor; most are really good): lessons tended to move through a lot of content at once, and we barely took time to explain the mechanics behind it.

Problems were thrown up on the board, and you were expected to know how to solve it “using your physics knowledge” (um miss, I don’t have that yet THAT’S WHY I’M IN THIS COURSE), and so on and so forth. I was so confused: in all of my other classes, everything was explained to me before I even attempted to solve a problem! Is this how physics was supposed to be? Why am I advocating for physics if this all happened? After weeks and weeks of this, I can say I learned a big life lesson during grade 12 physics, which I carry with me to this day: sometimes, you just need to persevere.

  1. Again, disclaimer: I realized all of this after grade 12.
  2. While I learned that my problems weren’t a result of the content, but of the presentation of the content, this course eventually taught me how to be resilient.
  3. I learned so much from taking on a course where I had to grit my teeth and bear it.
  4. I self-taught as best as I could.

I went and connected with friends who could help me understand more. While I may have taken the L on a couple of assignments/tests, I survived the course altogether. And in the end, I did leave with some pretty cool and relevant knowledge. When I got to university, I found myself very prepared for my first-year classes.

  • Physics in university was understandable, thanks to the knowledge that I had gained during high school.
  • But the most helpful part was my experience with resilience and stress; I could handle the workload, having had to juggle the three sciences — alongside calculus and english — before.
  • Physics taught me how to fail, but also how to pick myself up and keep going.

It’s up to you If you’re wondering if you’ll survive the course, I can easily answer that: yes, yes you will. And if you’re wondering if it gets better, I promise it does. I loved my university physics course, and I know part of that was because I understood a lot of it from grades 11 and 12.

  • I made it through grade 12 and half of my first year, and I can say with great confidence that, after taking a lot of time to reflect, the sequence of events that brought be here helped me so much (yes, including physics).
  • Choosing to take grade 12 physics comes down to what you want to do with your time.

In grade 12, you don’t have much time to spare, so making the most out of your courses, your day, and eventually your year, will always lead to a positive outcome on your end. If you know that physics isn’t for you, and that you would be sacrificing your own well-being to stay in the course, then you have every reason to choose something else.

Optics is the biggest unit of Class 12th Physics.

Is physics quantitative or qualitative?

30.26.1 Naive Physics – Classical physics is based on qualitative concepts that are then translated into quantitative mathematical models. Naive physics utilizes the same concepts but derives from them qualitative models. Work on naive physics has been described by Hayes (1979, 1985) Hayes (1979) Hayes (1985) and Hardt (1992),

The work on qualitative modeling by De Kleer and Brown (1984), Forbus (1984), and Kuipers (1984) also comes under this head. In naive physics, the physical situation is modeled formally but qualitatively. The modeling remains symbolic and the variables take a limited number of discrete states. Naive physics retains all the basic concepts of classical physics such as state, equilibrium, conservation of mass, momentum, and energy, but treats them in a qualitative way.

It follows the same sequence of model formulation, solution, and interpretation of the results. One way of looking at naive physics is that it is a formal encoding of common sense reasoning about physical situations. In many cases, particularly in mundane situations, it can be quite difficult to formulate a quantitative mathematical model, but it is feasible to derive a qualitative model.

In its own terms, the qualitative model can be made as rigorous as the quantitative one. A naive physics model can also be viewed from the opposite perspective as a reduction of a quantitative model to its essential qualitative form. In some work on naive physics models have been derived both by encoding of natural language statements and by reduction of the equations of a conventional mathematical model to qualitative model format.

The formalization of common sense reasoning about physical situations in a naive physics model is not easy. Common sense draws on large quantities of knowledge about the physical world and the forms of knowledge representation involved are often specialized.

Why qualitative method is best?

Conclusion – Qualitative research is very important in educational research as it addresses the “how” and “why” research questions and enables deeper understanding of experiences, phenomena, and context. Qualitative research allows you to ask questions that cannot be easily put into numbers to understand human experience.

What is the difference between qualitative and quantitative physics?

Conclusion – In conclusion, Qualitative Analysis is a theoretical analysis and involves establishing mathematical relations between various physical quantities whereas Quantitative Analysis is about verification of the formulation by the aid of data, readings and measurements.19,778 Views Published on December 17th, 2018 | by Abhishek Mandal

Which is the hardest chapter in physics class 11?

1. Heat and Thermodynamics – It is probably the most difficult yet one of the important topics for JEE Main Physics. Students who do not understand the application part of the topic often find it difficult to solve questions related to the topic. There are two main areas within heat and thermodynamics: conduction and convection (heat transfer).

These can be difficult concepts, even though they might seem like something that would come naturally when thinking about hot objects touching cold surfaces or heated air rising. Convection is a thermodynamics concept based on fluid dynamics and is vital for understanding the weather. In this case, you will be looking at how hot air rises from the ground due to lower pressure in certain areas, compared with high pressure beneath cold objects.

While studying these processes further, students should learn about entropy and its role when things heat up or cool down. That is where they need to start applying what they know about energy conservation and their knowledge of thermodynamic processes, such as evaporation vs.
