Hello,

I'm just confused on how you use the gradient with the formulas to find g and T. I know that the formulas T = 2π√(l/g) and g = 4π2l/T^2, but not sure how to sub in the gradient. Can somebody please help me?

Thank you,

Parrot

Don't you use rise over run

 

[Parrot]

Yeah I get the gradient value (rise/run) first, but then I don't know what to do with it.

Can they ask us to mathematically calculate the Period (T) using the gradient or just the g?

Yeah but highly unlikely, it's usually like sketch the line of best fit using the points then calculating g.

 

[Parrot]

I get how to find g using gradient, but how would you find T? (Just in case).

Time taken for 10 oscillations/10 = T

Is this the using "g" experiment?

 

[Parrot]

So T must be given?

You don't find T using the gradient because it's part of the gradient, so the only question they could ask to find T would be given 'g', 'l' and then all you have to do is sub into the formula.

Ahh. Alrighty. Thank you everyone! Much appreciated.
