Question 1169793: Hope this is the right topic. Sorry if it isn't!
The angle Φ represents the phase shift, determined by the initial conditions of the experiment or the position of the weight at t = 0. If the weight is at its maximum positive position (weight is above equilibrium) at t = 0, then Φ = 0. If the weight is at its maximum negative position (spring is stretched and weight is below equilibrium) at t = 0, then Φ=π. If the weight is traveling in the negative direction and passing through equilibrium at t = 0, then Φ=π/2. In the response box, describe the initial condition of our experiment; specifically, describe the position of the weight and the direction in which it was traveling.

            I want to make couple notices regarding this post. 


(1) It is WRONG to call the angle  Φ   "the phase shift", as the post makes it in its first sentence.


    Φ  is not phase shift - it is phase angle, instead.


    This one single fact shows me clearly that the "problem" is created by the person, who does not know base terminology 
    and base conceptions in full.




(2)  Now, the question asks to describe initial condition of the experiment.


     But they ARE JUST DESCRIBED in the text: the initial condition is WHAT HAPPENS at t= 0 ----- simply read your text.




(3)  Next, the question asks "describe the direction in which it was traveling".


     It is not absolutely clear to which time moment this request relates, but from the context, I may assume that
     the question relates to the time interval immediately following after t= 0.


     Again, the answer is clear from the text:  at t= 0 the weight was at its maximum positive position,

     so after t= 0 it moves down, obviously.


So,  my dear visitor,  I do not understand your panic:

    you simply do not want to read your own text or are not able to understand what is written in it.


The problem  ONLY  REQUIRES   __YOU__   read the text attentively and   __YOU__   find

    the answers to questions right  INSIDE  the  TEXT.



Have a nice day.

            "Hope this is the right topic. Sorry if it isn't!"


Surely, it is not a right topic for your post.


But at this forum NOBODY cares about the topic to which he (or she) places his (or her) post.


So, do not use these "introductory words" at all - they do not make sense and only IRRITATE.
