Potential energy converts to what type of energy when allowed to move?

When potential energy is allowed to move or is released, it converts to kinetic energy. This transformation occurs because potential energy is stored energy based on an object's position or state, and when that energy is released, it results in the motion of the object.

Kinetic energy is the energy of motion, and as the object moves, the stored potential energy is converted into kinetic energy. For example, a rock at the top of a hill has gravitational potential energy due to its height. When it rolls down the hill, that potential energy converts into kinetic energy as the rock gains speed.

The other forms of energy listed, such as gravitational, electrical, and chemical energy, do not directly result from the conversion of potential energy in the context of the question. Gravitational energy is essentially a category of potential energy itself, electrical energy pertains to the energy of charged particles, and chemical energy relates to the energy stored in the bonds of molecules. Hence, the correct and most relevant conversion for this scenario is indeed to kinetic energy.
