# Period of a Pendulum

Period of a Pendulum

### Recommended For You

You can see the second lighter ball, with the same length string, begin to not reach the same amplitude as the heavier ball. Is this why they use heavier weights in old clocks that use a pendulum? You get the same swing frequency with a lighter weight but it retards faster due to less momentum?

This is because the gravitational acceleration causing the pendulum to swing is independent of mass. For the same reason, two seperate masses will accelerate at the same rate when falling through a vacuum.

It depends on the gravity too. It depends on l/g , where l is the length and g the gravity

Source of video?

So surely a heavy pendulum mass is having to have bigger forces speeding it up and slowing it down again than a lighter one, where is that extra force coming from?

2pi.|(lenght/g)^2|

Wasn’t there a gif on here a few weeks back That had a pendulum designed to have the same period regardless of amplitude?

No shit, acceleration due to gravity is not affected by mass as long as mass is small.
