Pendulum Period Dependence on Length

Pendulum Period Dependence on Length#

Part 1#

What is the effect on the period of a pendulum if you increase its length by a factor of 4?

Answer Section#

  • It increases by a factor of \(\sqrt(\)4\()\).

  • It increases by a factor of 4.

  • It increases by a factor of 4\(^2\).

  • It decreases by a factor of \(\sqrt(\)4\()\).

  • It decreases by a factor of 4.

  • It decreases by a factor of 4\(^2\).

  • It does not change.

Part 2#
