    Angular Frequency and In-Phase Motion: A Scientific Inquiry

    But the question ask: why for in-phase motion is the associated angular frequency the lowest, intermediate or highest (obviously there are 3 normal modes). The answer is the lowest angular frequency, but the question then asks; is this to be expected? ie why is the lowest angular frequency...

    Angular Frequency and In-Phase Motion: A Scientific Inquiry

    My question is; why for a system oscillating in a normal mode does the lowest angular frequency relate to the particles in that system oscillating in phase. I understand that the signs of the corresponding vector are the same,but what relation is it to the lowest angular frequency. Thanks for...

    Can the Dot Product Determine Maximum Distance from the Origin?

    Why if A'.A =0 is the distance a maximum? I too have a question on this, and I'm failing to see why if the position vector and the velocity vector are perpendicular then the distance is a maximum if the above holds true. Cheers in advance Smithy
