| Topic | Practice Focus | |-----------|--------------------| | Mechanics | Solve motion graph problems, Newton’s law exercises | | Energy | Conservation of energy problems (roller coaster type) | | Waves | Wave equation v = λ·f, sound reflection distance problems | | Electricity | Build simple circuits on paper, use Ohm’s law in series/parallel | | Heat | Use Q = m·c·ΔT and calorimetry problems | | Nuclear | Half-life calculation exercises (e.g., carbon dating basics) | The 9th-grade physics curriculum in Lithuania focuses on
Key Concepts:
Example problem:
A crane lifts a 200 kg load 10 m in 8 s. Calculate work done and power. Key Concepts:
V = I × R
Think: “Voltage pushes current through resistance. More push = more flow. More resistance = less flow.”
