So let's first go to the rod, then, and make a comparison between the rod and the pendulum. - 2
So if you look at the rod-- and we use the pendulum as our standard, l-- with length little l-- then you see the period will be the same if 1 1/2 R is little l... 所以如果你看杆子-,我们用摆作为标准，长度为-,你会发现如果,1，1/2，R等于l，周期相同。 - 3
When we make the rod shorter, the pendulum vibrates faster.
