   Yeah Kevin, he is the same person that coined the term “cell”

   Does anyone know the formula to find frequency?

   hey what did everyone get for their spring constants? we got around 19 and 23

   Jordan: Our group got like 24 and 28 for the spring constant

   Does “damping” eliminate the impact of the maximum displacements?

   Did everyone’s spring constant decrease as their mass increased?

   To Richard: You mean for the experiment? It *should* be the same since it’s a constant, but it’ll be a little off because of the quick measuring. But for my group, the spring constant did decrease a little bit as our mass increased.

    hey ms. skinner sry i am not posting till today. i just got back into town last night from union’s scholarship thing then i had church this morning…anywho, can someone explain what we are talking about when yall say spring constants and so forth? i have been gone 2 days now and i am kinda confused. did we do a lab friday?

    sara-
    we found a point on the bottom of the spring to use as the starting point and we measured where it was on the meter stick. then we hung a weight on in and held it in the natural position that the spring is in. then we dropped it and measured how far down the spring was stretched. we did that a few times and then took the average of all of them. we subtracted the start position from the average of the others and got d. then we converted the mass hanger to kilograms and multiplied it by g to get Fw. then we converted d to meters and divided Fw by d. I hope that made sense… if it didnt let me know and i will try to explain better…
