SUGGESTED EXPERIMENTAL TECHNIQUE:
REQUIRED INVESTIGATIONS: (Error analysis required only for item 3)
Plot the measured period as a function of angular amplitude including a few error bars.
The accurate formula for period as a function of amplitude is:
where
and
is the angular amplitude.
The results follow:
Compare your plot (above) with values predicted from this table.
I. Plot period () versus length (
) and extend the curve to
.
Can you tell at a glance how
depends on
?
II. Plot vs L. What is the shape of this curve? What can you tell
from this curve about the dependence of
on
?
