Introduction to High School Physics: Modeling the Universe with Khan Academy

What is Physics?

• ⚛️ Physics is defined as the science of building models to explain how the universe works.
• 🔬 It involves taking observations, describing them with math, and using these models for prediction and understanding.

Course Topics Covered

• 🚗 We will begin by learning to describe motion, tracking positions, velocities, and accelerations.
• 💥 The course will then explore forces and Newton's laws as the causes of motion.
• 🛡️ Concepts like momentum and impulse will be covered, with applications in designing safety features like cushions and crumple zones.
• 🍎 A unified model for gravity will explain phenomena from falling apples to planetary orbits and astronauts floating.
• ⚡ Electricity and magnetism will be explored, including static charges, how they connect, and how motors and generators work.
• 🎢 Energy will be examined, focusing on its transformation, conservation, and its role in modeling systems from roller coasters to atoms.
• 💡 Electromagnetic waves, including light, will be studied, covering wave-like behaviors (bending, reflection) and particle-like behaviors for harnessing solar energy.

Learning Approach

• ✅ The course emphasizes more than just watching videos; it includes checking understanding, clearing misconceptions, and applying knowledge to real problems.
• 🎓 The goal is to build mastery and model the universe together.
