Which of these is NOT a form of energy discussed in the context of motion?

Latent heat is the form of energy that is associated with changes in the state of a substance, such as when ice melts into water or when water evaporates into steam. It is specifically the energy that is absorbed or released during these phase changes, rather than during motion. In the context of discussing forms of energy associated with motion, latent heat does not fit the category, as it does not involve the kinetic activity of an object or system.

In contrast, kinetic energy relates directly to the motion of an object; it is the energy that an object possesses due to its velocity. Potential energy refers to the energy stored in an object due to its position or configuration, such as an object raised to a height which has gravitational potential energy. Thermal energy is related to the temperature of a system and is associated with the random motion of particles within an object, connecting it to the concept of thermal motion. Hence, latent heat stands apart from these forms of energy that are directly linked to motion.
