Overview: This unit covers the essence of physics as a discipline, its scientific spirit, and its applications in modern society. It introduces fundamental physical quantities used to describe object motion: time, displacement, and acceleration. By studying the definitions, measurement methods, and graphical representations of these parameters, students will develop a physical mindset that transitions from qualitative observation to quantitative description of motion.
Learning Outcomes:
- Understand the scientific spirit of physics and its social applications, recognizing the broad prospects for future development in physics.
- Distinguish between instants and time intervals, and between distance and displacement, and be able to quantitatively describe displacement in linear motion using a coordinate system.
- Master methods for measuring displacement and velocity using ticker timers, sensors, and satellite navigation systems.
Overview: This instructional unit covers the complete process from experimental investigation to theoretical derivation, aiming to guide students in mastering the core laws of uniformly accelerated linear motion. Starting with experiments using ticker timers to explore how velocity changes over time, the unit gradually establishes mathematical relationships between velocity-time, displacement-time, and velocity-displacement. These laws are then applied to a special case—free fall motion. Through a STSE perspective, students will understand the practical applications of these physical laws in transportation development and aerospace engineering.
