Heat is defined as a form of energy transfer between systems or bodies due to a temperature difference. Its unit, the joule (J), is expressed as kg·m²/s², which reflects the energy required to move one kilogram of mass at one meter per second squared. This relationship is crucial for understanding thermodynamics and energy conservation principles. The discussion emphasizes the importance of grasping both the definition and the unit to fully comprehend the concept of heat in physics.
