Learning Objectives
- Understand the vector nature of momentum and impulse, and apply the impulse-momentum theorem to explain cushioning phenomena in daily life.
- Master the conditions under which the law of conservation of momentum holds, and solve one-dimensional collision problems.
- Use experimental data analysis (e.g., tape analysis) to verify the law of conservation of momentum and investigate energy transformations during collisions.
- Grasp the characteristics of simple harmonic motion: identify simple harmonic motion, understand the physical meaning of displacement-time graphs (x-t graphs), and perform quantitative calculations using relevant formulas.
- Understand dynamics and energy principles: clarify the concept of restoring force (F = -kx), and analyze energy transformations and mechanical energy conservation during oscillations.
- Application and experimental inquiry: master the period formula for a simple pendulum, learn how to measure gravitational acceleration through experiments, and understand the conditions for forced vibration and resonance and their applications in everyday life.
- Comprehension and modeling: explain the mechanism of mechanical wave formation, distinguish between particle vibration and wave propagation, and skillfully read and draw simple harmonic wave diagrams.
- Quantitative analysis: master the formula v = \lambda f = \frac{\lambda}{T}, and solve problems involving multiple solutions and wave speed calculations during wave propagation.
- Phenomenon explanation: identify and explain wave reflection, refraction, diffraction, and interference phenomena, and understand the causes and applications of the Doppler effect.
- Master Snell’s law and the concept of refractive index: measure the refractive index of glass experimentally and solve practical optical path calculation problems.
