With the spring stretched, the system of two blocks and spring has elastic potential energy. When the blocks are released, the spring pulls them back together, converting the potential energy into kinetic energy. The blocks will continue past the equlibrium position and compress the spring, eventu...

We remain committed to bringing inflation back down to our 2 percent goal and to keeping longer-term inflation expectations well anchored. Reducing inflation is likely to require a period of below-potential growth and some softening of labor-market conditions. Restoring price stability is essential ...
