How does physics serve to improve our understanding of physical systems?
Q. Want to help me out? Would be greatly appreciated. Here's all four: How does physics serve to improve our understanding of physical systems? How do the principles of physics effect your daily life? Describe something in nature that has become more compelling because of an understanding of physics principles Is it possible to describe the whole natural world (chemical and biological) with a small number of physical principles? If so, how? Is physics a redundant science? Do we now have a clear understanding of the interactions between matter and energy on all scales? Is technological application the main thrust of physics research today?

A. I could answer most of your questions with this: physics describes everything. It is the study of the natural world. But here goes: How does physics serve to improve our understanding of physical systems? Because physics tells us exactly what happens in these systems, it's more than just equations. Behind it all, physics can teach you everything you need to know about the system in question. How do the principles of physics effect your daily life? The most basic physical principles deal with particles and atoms and energy... that's pretty much everything in the known universe... so I think that accounts for ALL the events in your life. People underestimate how basic physics really is. All other sciences are built off of it, ALL of… [cont.]

A.

There are heaps of online High School level courses available from the cyber-schools but I'm guessing you'd probably get very bored, very quickly if you were to return to that level of simplicity.

Is it ok to take Physics (Calculus based) with a background of only College Algebra and Trigonometry?
Q. Hi guys, I just wanted to seek a little bit of your advice. I have not taken Pre-Calculus or Calculus before. But I have taken College Algebra and Trigonometry.

A. Depends on the difficulty of the University. If you're at MIT, University of Michigan, Virginia Tech or another top ranked science university then i would never go into a class under prepared. If it's in a community college there should be enough people that don't know what's going on anyway that you can get away with not knowing all of the calculus background for a calc based physics class

What can I do to go to a regular physics and calculus class?
Q. I'm currently in fundamental physics. I really dislike the class. We have gone over simple scalar and vector equations for two months. I taught myself up to integrational calculus, so I could keep up with a regular physics class. I'm working on a physics problem with finding the acceleration on top of a parabola. I need to use calculus for this. I also want to do a problem using Theory of Relativity and Loretz (sp?) Transformation equations. Is there anything else I can do to further my chances of going into a calculus and regular physics? I'm currently in Geometry for a math class and in 11th grade. Thanks for your input. It is greatly appreciated.

A. Talk to your teacher, especially if he/she teaches the other class. The point is learning the concept, rather than an equation, but your teacher should be able to help you, either learn the difference between classes (and whether you probably can jump or help focus your independent study). Then you might want to talk to your guidance counselor at school. If you are in geometry, you might want to add another math class at the semester to catch up with other college bound students at the semester. Or see if you can prove you can test out of the material (better have As). Another option might be taking a class by correspondence or at a local college.

What physics concept is responsible for the front wheels of a race car keeping it from nosing up?
Q. I'm studying for a physics exam and going through the problems at the end of the chapter. The question is: "The front wheels located far out in front of the racing vehicle help to keep the vehicle from nosing upward when it accelerates. What physics concepts play a role here?" My class is a conceptual physics class and the tests are centered around understanding the concepts. So if anyone could walk me through how to understand this problem that would be great! Thanks!

A. This is most definitely NOT a problem that have anything to do with what the said below people are suggesting. It's not an Acceleration OF gravity, but rather and Acceleration AND Gravity. The problem is actually taking two problems and mixing it into one. A common exam strategy. I haven't done the problem but I'm guessing that it's asking you to find out when the acceleration is no longer greater than the force of gravity.

A. It is called Droste Effect. But that is just the name of such artistic expression. Since you post this question under the physics category, perhaps you are looking for an explanation of the effect more than just the name. Basically the effect that you see in two mirrors facing each other or when you point your web-cam towards you computer monitor is a result of a feedback loop that goes on infinitely. When you include the computer monitor in the view of the camera and then the content of the compute monitor is again feed back into the monitor again. So it is a recursive loop of input going to the output and which again feed into the input again and the loop just go infinitely until resolution of the monitor cannot show any finer… [cont.]

Help with my physics course work, how does length affect the resistance of a wire?

I have done a piece of course work for physics, which is titled how does length affect the resistance of wire? i have done the aim, method, collection of data, conclusion etc now i need to do the evaluation, i have already commented on how i collected data safely, and the limitations. i have also wrote improvements. on my help sheet it says; note the presence or absence of results that are beyond the range of experimental error idk what that means! help :S note the presence or absence of results that are beyond the range of experimental error<<
A. When you do an experiment there is always some chance of error. Your ohm-meter cannot be 100% accurate. Perhaps it is very accurate, and has an inaccuracy of 0.01 % but it will never be perfect. There are all sorts of tiny variables, like the heat of the meter leads and the resistance of the wire in them. And so, whatever experiments you do will give you imperfect results. So if I measure what I think will be a 100 ohm resistor and get 99.9, I will probably be satisfied. I would feel that my results were within the range of experimental error: my 'set up' was anyway not more accurate than that. If, however, I got one reading that said that it was a 32 ohm resistor, I would know that that was not just 'experimental error', not just a… [cont.]

Asked by Pennsy Dutch - Sun Oct 26 14:56:51 2008 - - 1 Answers - 0 Comments
A. Depends what he or she meant by fully. The first equation would be working out how long it takes to reach the ground, and how fast it's going when it arrives. This is actually going to be a differential equation since the air resistance on the leaf will cause it to reach terminal velocity very quickly, and will have the form: F = mg - k(dx^2/dt^2). Terminal velocity will be reached when the net force is zero, i.e. the leaf is not accelerating but falling at a steady speed. Secondly, you may want to consider how the leaf rotates. This would call for an angular momentum equation. I can't think why it would be useful to do this, but you could come up with an equation describing the leaf's rotation by considering the position of its centre… [cont.]

Terminal velocity will be reached when the net force is zero, i.e. the leaf is not accelerating but falling at a steady speed. Secondly, you may want to consider how the leaf rotates. This would call for an angular momentum equation. I can't think why it would be useful to do this, but you could come up with an equation describing the leaf's rotation by considering the position of its centre… [cont.]

What math is generally needed for a regular high school physics course?
Q. At my school, you can take your science in any order you want, but all honours and AP courses require one year in that science. I have to take Biology, Chemistry, and Physics. I am currently taking Biology, and I can take physics next year and then chemistry after that. I was wondering what math courses are recommended for Physics? By next year, I'll have taken Algebra I and Geometry.

A. That question is really best answered by your counselor or the physics teacher at your school, since they know the requirements of your particular course. I can tell you that any physics course except a basic concepts-only course (which yours probably isn't) will require you to be able to solve basic equations routinely. You may also need to solve some quadratics using the quadratic formula. Most physics courses will also require some right triangle trigonometry, which is usually taught in geometry, as well as some knowledge of exponential equations (for radioactive decay) and logarithms (for relative intensity level of sound). The physics course that I teach, for example, requires that students at the very least take Algebra II… [cont.]

What work experience would help me get a career in Physics?
Q. I love physics and astronomy and I want to have a career in physics in my later life (possibly theoretical physics). What sort of work experience could I do to help me achieve this?
Asked by jasminegrosso - Thu Oct 22 17:03:01 2009 - - 3 Answers - 0 Comments
A. there are no "careers" in physics you can study physics at doctorate and post doc level but most of it will be theoretical, the only career in astronomy is as an astronomer and that is overpopulated

How much physics is involved in computer science?
Q. I am really good at math and really enjoy it, but for whatever reason, I hate physics with passion. Its by far my least favorite subject. How much physics is involved in getting a computer science degree and being a programmer or whatever? Thanks guys.

A. almost nothing. physics can help you to understand the hardware, but you can do high level programming disregarding hardware. unless you plan to code a physics engine for a game or for simulations, or to program physics simulations... you won't need physics
