Okay, I think I understand. Thank you for sharing your knowledge. Oh, I see. Thanks for the clarification.

If there appears to be observational/experimental evidence that quarks and leptons are not composite, and are indeed fundamental - shouldn't that dispel arguments for string theory? Or does the idea that such particles may be composed of more fundamental strings differ from the idea that quarks...

Thank you both for your responses. I'm not sure I understand what you mean, would you care to elaborate? It would be much appreciated. That's very interesting, I didn't know about the theorized preons. And thanks for the tidbit about the lepton colliders.

Centuries ago, Greek philosophers (such as Democritus) postulated that atoms were the fundamental building blocks of matter. Then, in the 1900s Rutherford along with others discovered that atoms consisted of electrons surrounding a nucleus made up of protons and neutrons. With the technological...

Yes, I was already planning on having some fun, and enjoying my summer but I also want it to get something valuable out of it. I will keep this in mind if I still have time after learning some Calculus. Yeah, I think this makes the most sense because I am fairly certain that my starting...

Hello all. I recently graduated from high school, and will be attending Penn State (not the Ivy League school, that's UPenn) in the fall. I plan to major in physics with the intent to pursue a PhD. During my senior year, I took an honors physics course and I received a B+ final average. However...

Oh okay, I see you what you mean now. The problem can be thought of as a Force of Tension problem, where the object is connected to a string. The. Spring mirrors the usual rope, and the force of the spring is akin to the tension force. Thanks for your help! And @haruspex, thanks for answering...

I am not sure I understand why you would balance the force of the spring and the force of gravity to find the final height of the mass.

I think I got it. Energy will generally always be conserved but never created or destroyed, with the possible exception of The Mass-Energy equivalence (E=mc^2). Then in a stricter sense, Mechanical energy is only conserved in the absence of forces which would release energy such as friction. Is...

Follow-up question: Could someone explain to me what the difference is between the Law of Conservation of Energy and Conservation of Mechanical Energy?

A spring with k= 53 N/m hangs vertically next to a ruler. The end of the spring is next to the 15-cm mark on the ruler. If a 2.5-kg mass is now attached to the end of the spring, where will the end of the spring line up with ruler marks? According to the book, the final reading will be 61 cm...

That was my question, for the purpose of making a schematic of an incline pane. I was going to label the base as "x" but then I questioned whether that was correct. In retrospect, it was somewhat of a dumb question because I don't really think this small matter would have affected any of the...

Does the distance traveled by an object sliding down an incline plane pertain to the base or the hypotenuse of the triangle? My guess is the hypotenuse, but I want to make sure in order to settle this matter once and for all.
