2010年12月7日 · 'wt' is essentially angular displacement. But when it comes to trig functions if y=Bsinx or Bcosx the maximum value of both sine and cosine is 1, so that the maximum value …

Simple harmonic motion is repetitive. The period T is the time it takes the object to complete one oscillation and return to the starting position. The angular frequency ω is given by ω = 2π/T. …

2018年9月15日 · The graph will have the equation x = Asin(wt). Now I try to break this down in order to understand why this equation is true for SHM. Firstly, as I said the variation of x with t …

It means that the quantity y(x, t) y (x, t) depends on the position in space x x in the same way as it depends on time – so even at one moment, it looks like the cosine wave in space. There is a …

2021年1月14日 · I know that both have a phase difference of 90 ' , but , if an initial phase is given , how to determine that it is p for x = A sin (wt + p) or = A cos (wt+p). You can explain with the …

2010年2月12日 · I know w is the angular velocity, A is the Area, and t is time. but what are NB? is B the field strength? If that is so, then what is N? Hi lampshader! Number of turns? Number of …

2017年8月15日 · Let's investigate "downwards": The wave solution describes the disturbance of some quantity from its equilibrium solution. It may be a displacement of a section of string from …

Power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt, equal to one joule per second. Power is a scalar quantity.

2025年3月16日 · We define periodic motion to be any motion that repeats itself at regular time intervals, such as exhibited by the guitar string or by a child swinging on a swing. In this …
