So far I've been doing pretty well this year. Managing at a 3.5 and currently only struggling in math because math just sucks. Gonna take the SAT soon and after getting a 1250 on the latest PSAT, I think everything has been going well so far. Not too worried about not doing well in math since i'm looking at becoming a registered nurse and math isn't exactly too much of a need for it.

How do you find the period of a swinging pendulum given its length? Do you have to know the gravitational acceleration, and is that always just 9.8 on Earth?

You would use the formula T=2πsqrt(l/g). Where l and T are the length and period of the pendulum respectively.

Is G always 9.8, or does the weight of the pendulum matter?

I know you did, but I wasn't sure if the weight of the pendulum was useful information or if it wasn't necessary

G (capitalized) is Newton's Gravitational constant and is equal to 6.67*10^-11, g (lowercase) however is the acceleration due to gravity and has the value 9.8. In this case g is the constant you want.

If you get really technical about it, it should actually be g (cursive), to avoid confusion with grams. That is just really nitpicky though.
