There isn't just one "Fizika 9" book; different schools use different series depending on the curriculum: Fizika 9 Fizikos Vadovelis 9 Klasei.pdf

Vladas Valentinavičius and Zita Šliavaitė (Šviesa): This is one of the most widely used classic textbooks. It typically covers Heat (Šiluma) and Electricity (Elektra) in two main parts.

"Horizontai" Series (Baltos lankos Klett): This series is updated to follow the latest 2022 general education programs.

Part 1: Focuses on thermal phenomena, including internal energy and heat engines.

Part 2: Concentrates on mechanics, covering motion, forces, pressure, and energy.

"Spektras 9" (Briedis): Another modern alternative that includes digital content and experimental tasks. Typical Curriculum Content

If you are using the PDF for study, expect to encounter these core themes: Problem: How much heat is needed to warm

Thermal Phenomena: Internal energy, heat transfer (conduction, convection, radiation), and the states of matter.

Electric Current: Voltage, resistance, and Ohm's law, often including laboratory work on measuring current.

Mechanics: Linear and non-linear motion, Newton's laws, and the concepts of work, power, and efficiency. Where to Find it Digitally
