The Slinky, like all objects, tends to resist change in its motion. Because of this inertia, if placed at the top of stairs it stays at rest without moving at all. At this point it has potential or stored energy. But once it starts down the stairs and gravity affects it, the potential energy is converted to the energy of motion, or kinetic energy, and the Slinky gracefully tumbles coil by coil down the stairs.
