A spring is characterized by a spring constant k (in N/m) which gives the stiffness of the spring, or how hard you have to pull to stretch it. If you connect a mass m on one end, and connect the other end to a fixed wall or ceiling, then the resulting system will vibrate. This vibration has period T given by
The frequency of the vibration is defined as
f = 1/T
In two trials, two masses are attached to a spring and the periods recorded. Mass P resulted in a period 36 times larger than the period of mass Q. What can be concluded?
