This simulation show 11 pendulums with different initial angle(from [u][i]minimum angle[/i][/u] to [u][i]minimum angle+angle range[/i][/u])
It can be run in two different modes:
1. (equation for real pendulum)
2. (equation for small angle approximation :assume )
The damping factor b=0 is the default.
You can change it and find out what will happened.
For the second mode: the period and damping rate are the same for all pendulums. Do you know why?
