identify the dependent and independent variables of the pendulum prac and JUSTIFY the use of these terms within this investigation

can someone help me ouuut?

ermmm ...

you know the formula T = 2pi√(l/g) right ?

√l is the independant variable, thats the length of the string, you can alter it throughout the experiment ...
T is the dependant variable (on √l) , because if √l changes, so does T.

a bit like y = 2 x +3 ... if x is 2 then y = 7, if x is 5 then y = 13 ...

as one mentioned earlier ...

Pendulum - what did you alter? The length of the string = independent variable because the change of the quantity is independent of everything else in the experiment because YOU did it.

What did you measure? Time/period = dependent variable because the change in this is completely dependent on the change you made.
