The second page focuses on power calculations, electrical principles, and motion measurements, providing essential formulas for practical physics applications.

Definition: Power (P) is defined as energy transferred per unit time, measured in Watts

Example: Using Ohm's Law: If a circuit has 12V and draws 2A, the resistance R = 12V/2A = 6Ω

Vocabulary: Resistance (R) - The measure of opposition that a circuit presents to electric current

Highlight: The relationship between power, voltage, and current $P = U × I$ is fundamental to understanding electrical systems

This page emphasizes practical applications in electrical systems and motion analysis, presenting formulas for power calculations, electrical relationships through Ohm's Law, and velocity measurements. Each formula includes proper unit specifications and clear variable definitions for accurate calculations.

This page introduces fundamental physical and chemical formulas essential for understanding matter and energy relationships. The content is organized into distinct categories for clarity and practical application.

Definition: Mass density (ρ) represents the mass per unit volume of a substance, measured in kg/m³

Example: Weight calculation: A 1kg object on Earth $g ≈ 9.81 N/kg$ has a weight of 9.81 Newtons

Vocabulary: Solubility $s$ - The maximum amount of solute that can dissolve in a given volume of solvent at specific conditions

Highlight: The mechanical energy formula (Em = Ec + Epp) demonstrates energy conservation by combining kinetic and potential energies

The page covers three main sections: matter organization (density and solubility), forces (weight), and energy calculations (kinetic, potential, and mechanical energy). Each formula is presented with its corresponding units and variables clearly defined.
