# Math Help - a sconds pendulum taks 1 s to move from one extreme to the other

1. ## a sconds pendulum taks 1 s to move from one extreme to the other

Hi
A sconds pendulum taks 1 s to move from one extreme to the other

what is time period ?
what is frequency ?

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

2. The period is the time it takes the pendulum to make one complete swing. If takes the pendulum 1 s to move from one extreme to the other, it take same time to come back- that total time is 2 s.

If you are expected to answer a question like this, you probably have a formula in your text or notes that connects the period with the length of the pendulum, l, and the gravitational acceleration, g. You probably are only expected to answer whether the time period increases or decreases. Is g in the numerator or denominator in that formula?

3. thanks but are this formula we use l/t ??

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

4. No, it is not. In fact, if l is a length and t is time, l/t will have units of "distance/time", say, meters per second", a "speed". You are asked about a "time period", with units of "seconds", not a speed. Now, what formulas are there in your book connected with pendulums?

5. what is the formula to use when found to time period and frequency the formula nor writen in our note

6. 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 ?

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