Yates says Atlanta has come a long way since the '70s. But Silicon Valley has several key advantages: easy access to capital and a network of seasoned entrepreneurs. And, Yates says: Maybe this is a cultural difference in the rest of the world versus the Valley, but it's the idea that in the Valley, it's OK to fail.
The angular frequency is measured in radians per second. The inverse of the period is the frequency f = 1/T. The frequency f = 1/T = Ï/2Ï of the motion gives the number of complete oscillations per unit time. It is measured in units of Hertz, (1 Hz = 1/s).
So-when velocity is maximum, displacement is zero, and when displacement is maximum, velocity is zero. The period of oscillation is the same, but the plots for displacement and velocity do not 'line-up' in time...one is shifted along compared to the other. This shift along in time is called a phase angle, which is an idea we'll come back to later.
