Period and frequency of a pendulum doesn't depend on mass??
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 mass m of the pendulum bob doesn't appear in the formulas for T and f of 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?
