And this was my favorite rocking chair, said Woolly to no one.
He was standing on the porch, a little while after Duchess had gone to the general store. Giving the chair a push, he listened to the thwapping of its rockers as it rocked back and forth, noting how each individual thwap came closer and closer together as the back and forths became smaller and smaller, until they stopped altogether.

The loss of energy due to friction processes makes the amplitud of the oscillation of the rocking chair lesser and lesser. It´s like a tennis ball released from high. The ball is loosing height until stopping on the floor. With friction forces acting, the mechanical energy is being lost. When the armonic motion moves into the space, this is why the wave intensuty become lower when get away from focus
How many readers have read the whole paragraph? As it were a wave, the number of readers have been decreasing while I was inserting technical terms.
