GRAPH CALCULATIONS:
AMPLITUDE: 0.1953 rad = PI/16 = 11.25 deg
AMPLITUDE: 0.3927 rad = PI/8 = 22.5 deg
AMPLITUDE: 0.5236 rad = PI/6 = 30.0 deg
AMPLITUDE: 0.7854 rad = PI/4= 45.0 deg
AMPLITUDE: 1.0472 rad = PI/3= 60.0 deg
AMPLITUDE: 1.5708 rad = PI/2= 90.0 deg
INTERACTIVE PHYSICS SIMULATION:
Pendulum length L = 0.7 m,
Mass m= 0.064 kg,
Fx (bottom trace) and Fy (top trace) are the horizontal and vertical components of the tension in the string.
