So the particles defined by their spin, and not by whether they are matter particles or force particles?

So I read that fermions can be defined as "matter particles," while bosons can be defined as "force carrier particles." I read further that fermions can be divided into quarks and leptons. However, apparently mesons are considered bosons, as a consequence of their spins. Does that mean that...

I couldn't find an appropriate place for this; this was the closest. If this is in the wrong place, could someone let me know? So I'm a sophomore in high school, and I"ve finished self studying Physics C. I'm taking the class oficially for the credits next year, but my main question is, what to...

So, I was trying to figure out the physics of frisbees. When you throw a frisbee at the ground at an angle (such that the side to the left of you, assuming you are right handed, hits the ground first), then it will suddenly skip up and fly upwards (Youtube has some great videos of it, for anyone...

I wouldn't worry about it. I might be wrong, but I'm fairly sure that an English grade, even if it counts on your GPA, won't affect you with a physics background.

Why isn't it (1/kequivalent)=(1/75) + (1/75) kequivalent=75/2 Isn't that the equation for springs in series? Also, why are those in series? I was under the impression that two springs on either side of an object would be considered in parallel...could you explain when a spring is in...

But aren't all these in parallel? Which two springs are in series?

Homework Statement A spring system is set up as follows: a platform with a weight of 10 N is on top of two springs, each with spring constant 75 N/m. On top of the platform is a third spring with spring constant 75 N/m. If a ball with a weight of 5.0 N is then fastened to the top of the third...

As a third grader, I personally found the idea that heavier things don't fall faster fascinating. Mind you, I was a complete nerd, so others might not find it as interesting. Maybe make a simple motor with a coil or wire, or make a parallel plate capacitor and get some tiny sparks in the dark?

But why would it only be extracted from the sponge in an air leak? In the good one, nothing showed up.

THe one that I was using had the pain spray painted onto it. It was essentially a jar, with a metal top. The sponge was attached to the metal, and the outside bottom of the jar was spray painted black. Incidentally, I found out that one had air leaks. I made a new one with sheet metal and a...

I recently observed a liquid pooling at the bottom of my cloud chamber. It was purple in color and rather odd. It was certainly flammable, which leads me to believe that it was a result of solventing between the supersaturated alcohol and the canned air used for my chamber...

I'm clearly doing something wrong then, as I'm arriving at the correct answer with 0.5mr2. Could you explain why? I thought a hoop was given by 0.5m(a2+b2). If b goes to 0, or essentially 0, then wouldn't it simply be 0.5mr2. I did Ia/r = τ Plugging in what I thought I was equal to...

So with the parallel axis theorem it would be 0.5mr2+mr2 = 1.5 mr2? I initially took the moment of inertia about the center of mass to be mr2, but it would actually be 0.5mr2, correct? As the outer radius essentially goes to 0. I managed to do it this time, and I think that my essential...

Homework Statement A hollow cylinder with a very thin wall (like a toilet paper tube) and a block are placed at rest at the top of a plane with inclination θ above the horizontal. The cylinder rolls down the plane without slipping and the block slides down the plane; it is found that both...
