Page 1: Physical Quantities and Units

Page 1 introduces the concept of wielkości fizyczne (physical quantities) and their corresponding units. It covers fundamental physical quantities such as mass, length, temperature, volume, and surface area.

Vocabulary: Wielkości fizyczne refers to measurable properties of physical systems, such as mass, length, and temperature.

The page also presents a table of SI prefixes, including:

• Giga (G): 10^9
• Mega (M): 10^6
• Kilo (k): 10^3
• Hecto (h): 10^2
• Deka (da): 10^1
• Deci (d): 10^-1
• Centi (c): 10^-2
• Milli (m): 10^-3
• Micro (μ): 10^-6

Example: For length, units range from kilometers (km) to micrometers (μm), illustrating the wide range of scales in wielkości fizyczne.

The page distinguishes between scalar and vector quantities, which is crucial for understanding wielkości fizyczne i ich jednostki (physical quantities and their units).

Definition: Scalar quantities have only magnitude, while vector quantities have both magnitude and direction.

A comprehensive table is provided, listing various wielkości fizyczne with their corresponding units and symbols. This table serves as a valuable reference for students studying wielkości fizyczne klasa 7 (physical quantities for 7th grade).

Highlight: The table includes common units such as kilograms (kg) for mass, meters (m) for length, and Kelvin (K) for temperature, providing a clear overview of podstawowe wielkości fizyczne (basic physical quantities).
