DESCRIPTION

Computer and sensors are used to monitor and plot force on sensor and position of mass in real time.  One can plot x, v, a, F, K, U, K+U vs. t or x.

Overlay x vs t graphs for different masses to show that T is proportional to m^1/2.

NOTES

Use cage to protect motion sensor from falling masses.

Zero force sensor in vertical position before collecting data.

Check that force sensor # agrees with calibration file.
k = 3.2 N/m.
