for a pendulum:

T = 2[itex]\pi[/itex][itex]\sqrt{}length/g[/itex]

and f = 1/2[itex]\pi[/itex] [itex]\sqrt{}g/length[/itex]

The massmof the pendulum bob doesn't appear in the formulas for T andfof a pendulum

where T = period

and f = frequency

How does this make sense? If you use a force to push a light child on a swing and use the same force to push a heavy child on a similar swing, the light child should swing faster, right?

bc F = mass x acceleration ... so the one with the lighter mass should accelerate faster therefore its frequency should be higher...?

but according to those equations, the mass doesn't play a role... why?/ how?
