👉 Physicalities in physics refers to the characteristics of an object or system that are directly observable and measurable. These characteristics include mass, length, width, height, density, temperature, pressure, and other properties that describe how a physical entity behaves under various conditions. In physics, physicalities can be categorized into two main types: static and dynamic. Static physicalities refer to the properties of an object or system without any external forces acting on it, while dynamic physicalities involve the interaction between a system and
