Question

Calculate the slope of the line in your graph of the square of the period of the pendulum vs. length of the string [slope = (y2 – y1)/(x2 – x1)]. Galileo figured out the equation that describes the behavior of a pendulum. If you square both sides of the equation, you will find that the slope of the line is related to the acceleration due to gravity (g). Specifically, slope = 42/g. Use your data to calculate g. How does it compare with the accepted value of 9.807 m/s2? @satellite73

Answer 3

@Astrophysics

Answer 4

What is the equation, and what does your graph represent?

Answer 5

g = 4π² / slope.

Answer 6

my slope?

Answer 7

No I'm asking, the formula you're testing is \[T =2 \pi \sqrt{\frac{ L }{ g }}\] correct

Answer 8

oh ok yeah and I can also use T² = 4π²L/g

Answer 9

Ok and what does your graph represent, (y as a function of x) state the variables

Answer 10

thats when I get lost sorry

Answer 11

Ok no worries, note that we are determining gravity right

Answer 12

yes

Answer 13

Ok so you gathered that data right in the table?

Answer 14

yes

Answer 15

Ok cool, so what do the table represent?
