i don't understand physics reddit

Actually, that’s a bit of an understatement. I know engineering would be an option, but what do you think specifically, and any other degrees outside engineering, such as another science like geology for example? So, when you are thinking about the ideas, think from a mathematical standpoint. Physics is an unnatural act. we define it by defining how it acts on other particles. DonPedro. Suggestion: email the same plea to the chair of the physics department and ask her to recommend a professor you can discuss this with. Don't worry, at first E&M is very difficult, but after a while you get used to it and it becomes more natural. -/u/fineillmakeausername ~reddit bot So for example, I understand my electromagnetic fields classes way more than I ever understood physics II and the problems are way more involved than physics II . Any tips to get better at physics? I am a freshman in college level physics, studying to become an engineer. Or the concept of an electric field - the book says to envision that a body "somehow modifies the space around it". Naked Science Forum GOD! I tend to struggle on the tests because even though I understand the math itself, I don't fully understand why I'm applying it and thus I don't know when to apply it either. Showerthought: "Animals don’t understand the concept of an accident. is very well expressed and shows you have exceptionally curiosity...that will be valuable if you become a professional physicist. You know that equal charges reppel and different charges attract. How to Study Physics: 5 Techniques to Improve your Memory 1. Now I'm doing Physics since I'm in 12th grade. If the electric force is negative, the two objects attract. The koans are of his own imagination, so they don’t function as a nonsensical alternative history of physics. Is an electron more than its behaviors? Try to Understand the Situation. like what more is there to a number. I understand that charged particles behave a certain way, but why? I can understand Calculus II but damn physics just doesn’t like my brain and vice versa. Posts should be pertinent, meme-free, and generate a discussion about physics. I can't seem to see the problems as anything beyond solving for some value, whether it's the current, or the magnetic field, or whatever else. In order to measure the potential difference across a resistor, should a multimeter be connected in series or in parallel with the resistor? Understanding the answers doesn't matter if you don't understand why they are the answers. Usually because they remember material for a class they are taking, but when the class is over it is forgotten next semester. I have to constantly ask stupid questions and I feel like I’m the least popular in my class because of it. Well, that one explains that the electric force between two things is defined by the product of their charges, times the constant K (someone discovered it), divided by the square of the distance between them. I sometimes scroll through popular to discover new subs. New comments cannot be posted and votes cannot be cast. In so many videos I get people leaving a sweeping comment "You don't understand physics." Although this test is quite comprehensive, there are a couple of things you don’t need to fret about. Please report trolls and intentionally misleading comments. Physics is about explaining the behaviors we see around us using mathematics. In my final year, I realised that the only thing that separated me and the people who could was the amount of work we put in. Your question "OK, but what is it?" what's a number? I don't understand why affirmative action would be a problem for physics departments. Maybe intelligence determines whether or not one remembers things from one class to the next, but I think it has more to do with motivations and incentives (e.g. When we use vectorial quantities the negative sign stands for an opposite direction. As an outsider, I'll say that I see the jobs of a physics department as a) making physics b) making physicists c) teaching physics d) funding making physics. The easiest way is always to ask yourself "For every action, there's a reaction. Think a little bit like Isaac Newton. You can be an engineer, but not a good one and the same goes for all other scientific fields. Ask Question Asked 1 month ago. I don't understand physics? 3. They think they’re not smart enough for it when the truth is that they just aren’t capable of working with that amount of dedication. You've asked a deep, sweeping, historic question...no need to wrestle with it alone. Others struggled, and had to work hard, but eventually figured out the material. Engineering is still fairly heavy mathematically though just not as intense as Physics. The reason there are so many examples of bad engineers is because engineering attracts people who aren't capable of doing the work but want the job security while physics has no such job security. This is what he has to say when students tell him they just don't understand physics. Now why does this happen, we don't know. This suggests two approaches to take. i think you're not realizing how undefined things can be. We often reject "phenomenological" models as not being appropriately ground in more foundational theories (so there's clearly an explanatory hierarchy), etc. The sings + and - were assigned by humans, you don't need to overthink it; it's just a way to tell us the behaviour of the force. A positive charge will have the vectors point away from the charge, and a negative charge will have the vectors point towards it. If you do not understand the physics and the mathematics, you may wish to engage the services of a one-on-one tutor who can help you through the course. And don't be fooled into thinking engineering will be any easier. My E&M professor showed us these and I feel they really do help you attach the concepts to the math and equations. Right now I'm learning about kinetic and potential energy along with springs. I've seen many 'smart people' crash and burn and many 'dumb people' succeed. Pushing it further sends you straight to metaphysics and philosophy. If you go further into physics, you will learn that, basically, all elementary particles each have their own field, and a particle is just an oscillation of this field at a given point in space. I've enjoyed my course more, been less stressed, and in my second year I held a part time Job at an industry leader in town. HW Help. So, whenever a new theoretical concept is introduced, an new equation is also, (in most cases). I hate physics, I don't understand! 36 0. I don't understand this physics problem? The force on a charge in an electric field is qE, or the charge the force is acting upon times the electric field at that point. The math part of it is no problem to me. I've failed physics II twice before understanding that I had to get away from it in order to move on and graduate. When we talk about charges, we are talking about the amount of atomic particles in something ('+' is for protons and '-' is for electrons, yeah we chose the signs for both). it's defined by its operations and relationships with other numbers. The problem is the actual physics. This cannot be exactly right. It makes sense to me that in a series circuit that voltage changes as it goes through a resistor. I don't see that in many people. I think some people just may not be cut out for it. what else could be possibly be defined about it? Because the phrase connects research, teaching, and learning, it seemed the right approach for the talk I gave to the AAPT on receiving the 2013 J.D. Many people just try to jump to advanced concepts without having a deep understanding of the basics. Your original question (plea?) Whilst computer science may not be for you, necessarily, don't feel like you can't change degrees, or that you're not intelligent enough for a degree. If it wasn’t that they calculate Physics marks in conjunction with Chemistry marks I would never have been able to pass Science at school. I'm just an amateur in physics, but my understanding is that concepts like "electric field", "positive charge", "electron" are abstractions that help us understand and predict behaviors. Search engine: XenForo Search; Threadloom Search; Search titles only By: Search Advanced search… Search engine: XenForo Search; Threadloom Search; Search titles only By: Search Advanced… Hi Guest, check out the latest SDN … Eventually you'll have to come to grips with the fact that this is the universe we happen to live in, and the only way to learn about it is through empirical observations. Physics sounds horribly complicated, but most of its basic level questions are similar – once you get the concept, you get the solution. 8 0. Can't understand physics Thread starter piisexactly3; Start date Feb 12, 2014; Feb 12, 2014 #1 piisexactly3 . Physics and Mathematics are extremely important subjects. We discuss some top tips below to help you gain an understanding of physics and achieve good exam results in this subject. I imagine you appreciate the theory much more. They explain it in a way that might be easier to grasp than your textbook or lectures. Posted by just now. We continue our “How to Study…” blog series where we share the best tips and techniques for improving your study of different subjects. This is likely the last physics class that I will take, but I still want a good grade. Introductory Physics Homework Help. So, at this point at least, don't worry about why something happens. Nobody knows why there are protons and electrons. If I realize that I’m just not cut out for the heavy physics/math in a physics degree, what are other degrees somewhat related to physics do you think i should pursue? Think about if you’re cut out for a PhD, I definitely am not so I’ve decided to just do a masters. 145 11. :), You gotta strike a fine balance between having a physical intuition and understand of the content while also deeply understanding the math. What matters is how much you are willing to put in your best effort. Our university is famous(lost accreditation) for a bad physics department though. Press question mark to learn the rest of the keyboard shortcuts. I actually switched from physics to engineering (my degree is in EE) and I want to second this. Also, you are going to be in a position to decide to contact an idea with the way to translate percentages into the numerical grade point common. Yeah, I'm not so sure about this really. HELP! Beyond this, though, we don't know why this happens, it just happens and we are able to explain it using math. It is not a sudden revelation, but a journey. But something you should keep in mind is that people underestimate the need for struggle and hard work. This is a fantastic way of learning things, good job. my guess is your looking at its other properties and thinking it's more complicated than being described by a single number. In physics (and most other courses), everything is built up gradually from the ground up. I don't understand the articles about texture mapping. I am currently a sophomore in college working on a math major. The truth is that no one “just understands” physics. That and, well, the salary.In basic physics – material covered in high school and low level university courses – the methodology is straightforward. For example, just what exactly is a positive and negative charge? it changes too. that's all you need to know. Relevant Equations: See attachment solution. The phrase “I don’t understand my physics class. The battle for Bengal, to be fought in polling booths in a couple of months from now, is today being fought in Kolkata over the legacy of iconic freedom fighter Netaji Subhash Chandra Bose. If the football has a mass of .58kg, & the time of contact with the ball is .013s, what is the force exerted by teh ball on the kicker's foot?
