Energy is hard to define because it comes in various forms and can be transferred or transformed in many ways. Additionally, energy is a concept that is used to describe the capacity of a system to do work or produce heat, making it abstract and difficult to pin down with a single, universally agreed upon definition.
Scientist define energy as the ability to do work or to cause change. It is a scalar quantity that can be transferred between objects or converted into different forms. Energy exists in various forms such as kinetic, potential, thermal, chemical, nuclear, and electromagnetic.
Energy is the ability to do work or cause change. It exists in various forms such as kinetic energy (energy of motion), potential energy (stored energy), thermal energy (heat energy), and chemical energy (energy stored in the bonds of molecules).
My answer about heat is that heat is a form of energy which causes the sensation of hotness and coldness.And thermo dynamic is one of the characteristics resulting from the conversion of heat into other forms of energy.
In simplest terms, forms of energy.

Latent heat is the heat required to achieve a change of phase - for example, to melt ice and convert it to water. As to the relationship with potential energy, latent heat IS a type of potential energy.
Cold and heat are related in that they are both forms of thermal energy. Heat is the presence of thermal energy, while cold is the absence of heat. Cold can be defined as a lower level of thermal energy compared to heat.

Heat is referred to as the graveyard of kinetic energy in that once kinetic energy has been transformed into heat, it is no longer usable.
