slope

simple pendulums

T²

slope = 4.05

intercept = 0.34

T represents period
L represents length
g represents gravity

Use the numerical value of the slope to determine the experimental value of acceleration due to gravity (g) in this experiment.

If the correct value for g is 9.8 m/sec², what is the accuracy, or percent error, for this experiment?

Use the equation of the line to interpolate the period of a pendulum that is 4 meters long.
