units ??
This should be straightforward but I'm not sure what to do. If I make a graph and the Y axis is in cm, and the X is in g, does cm/g make sense?
I'm trying to find the spring constant 'k' by using the slope of my graph. When I do this I get a huge number so I'm playing with units to bring it down.
k = g/slope (g = 980 cm/s^2)
using the info. gathered my k = (980 cm/s^2) / 0.073 = 13520.55
this sounds extremely high. My slope units are what's throwing me I think. Does 0.073 cm/g make sense? Then, would the units be 13520.55 g/s^2 ?
I believe k is supposed to be in N m, so I'm not sure this is right ?!
