    Dimensional consistency problem, need help

    I think I understand what you're saying, but that doesn't really answer my question. Why were the constants put there in the first place if they were ultimately irrelevant in the conversion process? I mean, another conversion problem was posed on the website related to dimensional analysis...

    Dimensional consistency problem, need help

    This is hard for me to understand, and I probably need to enhance my mathematical skills as it relates to physics. However, during the entire time of trying to make sense of the equivalence, I kept thinking about multiplying 2 times 3.14 or something like that, and connect it to the rest of the...

    Dimensional consistency problem, need help

    Beginning student striving to learn. The problem was generated by people from the University of Winnipeg. Source: http://theory.uwinnipeg.ca/physics/ (this website was actually suggested by a user on the forums who suggested utilizing it as a learning source). Homework Statement Problem is...

    Confusing Students with Fractions

    Well in my opinion, this indicates either a tremendous misunderstanding, or miscommunication between the teacher and the student. If the students were properly taught, they would understand that the two fractions (or ratios) could not be added in that manner. Even the most contemporary teachers...

    Is there anything with a constant weight?

    Yes, you are probably right regarding the electron and proton decay, and how that relates to having weight. I'm not knowledgeable about these metric particles having 'weight'; and I was referring to elementary particles in gravity, and I thought that was what the OP was talking about. I was...

    Is there anything with a constant weight?

    OP: "Is there any measurable particle that is always the same mass "exactly" in vacuum? It seems to me that all particles have variable sizes and eventually some decay into other particles. Im looking for something that is stable and always has the same mass (no variance) in vacuum" I was...

    Is there anything with a constant weight?

    This is absolutely true; but it doesn't change the fact that it does have a force. Now, trying to talk about a "weight" given these weak gravitational forces because it is inversely squared as the distance increases, the vacuum particles do not have this "weight" that the OP was trying to refer...

    Is there anything with a constant weight?

    I think I get that, and I appreciate your post. However, if gravity is irrelevant, wouldn't that make weight irrelevant as well? Or aren't particles at these levels based on 'strong' and 'weak' fundamental forces, connected to the gravitational force as well related to weight? If that makes...

    Is there anything with a constant weight?

    I appreciate that and this site. And I will definitely refer to you in the future. But for a layman, attempting to understand these complicated physical questions, the equation that you've recently posted in my opinion, is "elementary' or a Newtonian understanding of the world. For instance...

    Is there anything with a constant weight?

    I have a BA in Sociology. However, physics has just recently grabbed my attention, which is why I asked for that elementary understanding of the equation, and respond to the original post to the best of my ability. I signed up on this site to give my understanding of the subject, and ask...

    Is there anything with a constant weight?

    Oh okay, and you are absolutely right. That's what I intended to say, as in the mass of an object related to weight, is subject to the gravitational force....so, you or I, would weigh much more on Jupiter or the Sun for instance. I understand the simple equation of F=mxg, but can you explain the...

    Is there anything with a constant weight?

    Oh I see. Please correct me if I'm wrong, but is this effect related to Einstein's theory of general relativity? Now that I think about it, maybe I was wrong by saying the effect of weight was necessary of having a greater massive object force. But, perhaps it's more dependent on the mass times...

    Is there anything with a constant weight?

    Care to elaborate on my mistake? Really interested. Thanks.

    Is there anything with a constant weight?

    Weight is directly dependent on the mass of X and the gravitational body of something even more massive. To technically answer your question, everyone on this planet has a constant weight, to some degree. So, your weight is directly dependent on the force of G. Therefore, I don't think there...

    Can anyone help with the perception of temperature difference?

    Oh, now I think I understand. Thanks for your response. So in a general sense, it's because the air surrounding me is at a lower temperature than the air coming from my body..which has the "cooler" perception of temperature. Am I accurate in this response? Wow, I never thought of that! Now it...

    Can anyone help with the perception of temperature difference?

    Okay, so you're saying that it has to do with the air around me? Is the lower pressure (generated by me blowing) causing the perception of cooler air then? I never considered the relationship between the air inside my body and the air around me. In addition I did put my finger closer to my...

    What is energy?

    I believe someone with more knowledge about quantum behavior will eventually answer your question. A sci adviser on this site who goes by the name of "bhobba" has answered my questions about quantum behavior related to light; I believe he can adequately answer your question on quantum energy if...

    What is energy?

    That's a very good question. Obviously, energy has some trasferential property, that is....observations have demonstrated that it could be converted from one thing to another. In the same way of how a car motor works. On a macroscopic level, heat seems to be commonly generated from this...

    Can anyone help with the perception of temperature difference?

    For some reason I'm having a difficult time understanding the reason why air 'feels' cold when you tighten your lips and blow air from your body, yet it 'feels' hot as you exhale with a widened mouth. Why is this so? The only reason why I'm having considerable difficulty is because I keep...

    Question about sound.

    That's interesting! This is why I love physics...so much to learn. Alright, I'll have a look at this article while simultaneously learn more about sound and give a response..thanks for the link!

    Question about sound.

    Conducted some brief research, so I think you're talking about the Pistol Shrimp. In this case, I'd think the claws would absolutely be moving faster than the speed of sound (supersonic like you pointed out) in order to produce a temperature hotter than the sun in the water. In fact, the force...

    Do the quantum effects we observe in visible light occur in all wave

    Hmm, I have to think about this more. However, that's extremely interesting and perhaps, that's the quandary that physicists are in at the moment I suppose? Nevertheless, I'll look at the link and learn more; while at the same time posing more questions if that's okay? Thanks for the response Bill.

    Question about sound.

    Okay, so I was listening to someone via tinychat explaining how our current understanding of sound was wrong in some sense. He claimed that the source of the propagation of sound waves HAD to be moving faster than the speed of sound (in air). One particular analogy he used in order to...

    Recommendations for Study Materials [QM]

    I'm starting from the very bottom of learning physics, and with my personal experience, I've found that mathematics and physics (including astrophysics) have an intricate relationship with each other. However, given your case, I'm not exactly sure why the mathematical understanding of quantum...

    Do the quantum effects we observe in visible light occur in all wave

    Wait, so after reading the post of the first link, is light actually a wave or a particle? Or it is possible for light to be both, given certain conditions?

    Man thanks for the links, I will look more into this.

    Do the quantum effects we observe in visible light occur in all wave

    Hello everyone, I'd like to start off by expressing my appreciation for the existence of this forum to begin with. I majored in Sociology, yet classical and quantum physics has grasped my attention to a whole new level. Basically, I have a very elementary understanding in the subject, which is...
