As the period increases, frequency...
|
DECREASES
|
|
|
Which factor(s) affect(s) the length of the period of a pendulum: amplitude, mass, string length?
|
STRING LENGTH
(not amplitude due to speed canceling distance; not mass due to acceleration due to gravity being constant for all masses) |
|
|
Which factor(s) affect(s) the length of the time for damping to occur with a pendulum: mass, string length?
|
MASS (because of momentum/inertia) and STRING LENGTH
|
