A bob on a massless string released from rest at angle θ0. The motion is integrated with the full sin θ equation, so you can see where the small-angle period formula stops working. Angle is positive to the right.
t = 0.000 s
θ — angle vs t
ω — angular velocity vs t
KE PE Total — energy vs t
Data table
Try: record T for several lengths, then plot T2 vs L. Press D to record.
