Formula

T = 2π √(L / g)

Notice that changing mass does not change the period in this simplified model.

Try this

Make the pendulum period longer than 3 seconds.

A longer length or lower gravity increases the period.

Learning Objectives

  • Longer pendulum means longer period.
  • Stronger gravity means shorter period.
  • Mass does not affect period in this simplified case.
