Energy of one type can be transformed into other types of energy. The pole vaulter makes an approach, bends the pole and "flies into the air". The chemical energy in his organism, which has well developed muscles, is transformed into mechanical energy as he runs, and this, in turn, is transformed  into elastic energy when he bends the pole; the energy of the bent pole communicates potential energy to the vaulter which permits him to overcome the obstacle, or not.
Which energy transformation is captured in the following picture?

Salto con pértiga
