Inqusitive: How exactly are the four laws of physics different and how is gravity even a 'force'? I read an intro on the four laws of physics and to me they seem like the same law of gravity/attraction... just on different size scales. For example; in electromagnetism, Isn't 'magnetism' a form of gravity since it is basically attraction between … [Read more...] about How exactly are the four laws of physics different and how is gravity even a ‘force’?

James T Phillips: What physics are involved in a typical pendulum experiment? I'm trying to design an experiment using a pendulum and am required to state the primary physical element that is involved in a pendulum. Of course, now, I'm having a brain relapse and can't remember anything about physics in regards to a pendulum except for energy and … [Read more...] about What physics are involved in a typical pendulum experiment?

xr0b0t: How important is it to take physics before attending college if you're majoring in biochemistry? I don't plan to take physics in high school next year, because I've been told we have a terrible teacher and he apparently gives a huge homework load that I definitely don't need this year. I am planning to take it over the summer at a local … [Read more...] about How important is it to take physics before attending college if you’re majoring in biochemistry?

Nightvision: How important is mathematical intuition in physics and other sciences? I just feel like I don't have that math "sense" that some people do, and I don't just get math like some of the really smart people in my school. However, I work really hard and I got top grades in Calculus AB and BC. In classes like AP Physics C, I can also get … [Read more...] about How important is mathematical intuition in physics and other sciences?

: How to show the physics behind a supernova in a presentation? My final project in physics is to demonstrate the physics behind something, and I picked supernovas! Except, there's so much to it and to explain, where should I center the info so it's not too long? Also, is there any way to actually physically demonstrate something similar to a … [Read more...] about How do I show the physics behind a supernova in a presentation?
