How to Calculate Time Period and Frequency?

AI Thread Summary
The discussion focuses on understanding the concepts of time period and frequency in the context of a seconds pendulum, which takes 1 second to swing from one extreme to another. The time period is identified as 2 seconds, while frequency is calculated using the formula f = 1/t, resulting in a frequency of 1 Hz. Participants explore how the time period of a pendulum would change if taken to the Moon, noting that gravitational differences would affect its period. The conversation highlights the importance of understanding the formulas and their applications, as well as the units involved, specifically Hertz (Hz) for frequency. Overall, the relationship between time period, frequency, and gravitational acceleration is central to the discussion.

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 written in our note
 
Physics news on Phys.org


see... if you can define time period and frequency ... well, your problem would be solved!

You don't need formulas for everything... sometimes you got to make them on your own...meaning every formula can't be stuffed into any book... many change according to the given problem.
 


I try ,,,,

what is time period ?

it's = 2s

what is frequency ?

but the solving frequency by formula

please hlep me .
 


what kinda english is that?

anyway, your time period is right and
f=1/t
 


The legend said:

Probably non-native.
 


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

What is unit of t? Take a look at the equation - what unit do you get from calculations?

what happen to the time period if you take your pendulum to the moon ?

Do you know any formula describing pendulum period?

i think the answe is 1s^-a are this uint and answe correct .

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

I think I told you I have a life outside PF? I am playing Fallout 3 if you are really interested.

s-a - I have no idea what you mean by a, so I have no idea whether you are right or not.

Question was not about "increasing the pendulum" (whatever it should mean), but about moving it to the Moon. There is a grain of truth in your thinking - period of pendulum will change because gravitational attraction on the Moon surface differs from the attraction on the Earth surface.

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?
 
  • #13


it will come shorter

^^ i don't think so...

What is the formula used for period calculation, which values are constant and which are changing when you move from the Earth to Moon?
