A sconds pendulum taks 1 s to move from one extreme to the other
what is time period ? what is frequency ? what is the formula to use when found to time period and frequency the formula not writen in our note

see... if you can define time period and frequency ... well, your problem would be solved!
You don't need formulas for everything... sometimes you gotta make them on your own...meaning every formula can't be stuffed into any book... many change according to the given problem.

what kinda english is that?
anyway, your time period is right and f=1/t

my language is not english
anyway, f=1/t that mean 1/1 = 1 but the unit should be what ? what happen to the time period if you take your pendulum to the moon ? please I want your help thanks

my answer is when we increase the pendulum the time period will decrease because there is inverse relation between time and acceleration of gravity help me

sorry i mean s^1 is this correct .
about (period of pendulum) will change because gravitational attraction on the Moon surface differs from the attraction on the Earth surface. here (period of pendulum) or (period of time )

s^{1} is correct. This unit has its own name  Hertz (Hz).
OK, period of pendulum will change  but will it get longer, or shorter?
