    Mind boggling attempt to apply Newton's 3rd law

    In classical mechanics, it's pretty straight forward for me to apply it(sometimes...), and really intuitive to picture it. However, when I kick it up a notch... to apply Newton's 3rd law in electrodynamics, my brain malfunctions... Simplest example I can think of, a conductor carrying a wire...

    To which bodies can we apply the concept of torque?

    I am in introductory physics, and have just been introduced to the topic of toque. For forces in translational motion, I know that we idealize objects to be point particles. However, when it comes to torque, we don't deal with point particles, but with "lever arms." I guess essentially my...

    Why Does Bernoulli's Equation Apply to Wind Tunnels?

    I hope this question doesn't have too obvious of an answer. Basically, I still cannot grasp why Bernoulli's equation applies for wind tunnels and pitot-static probes. According to my textbook ("Introduction to Flight" by Anderson), Bernoulli's equation holds only when comparing two points...
