Скачать или смотреть 2.1 Projectile motion Part 2: Physics Grade 12

Welcome to our Grade 12 Physics series! 📝
This video is your in-depth guide to Chapter 2.1, which focuses on Projectile Motion: The Basics. This essential mechanics topic is key to developing a unified understanding of two-dimensional motion under the influence of gravity alone. We will break down the definition and characteristics of projectile motion, introduce the key assumption of negligible air resistance, and explain the crucial concept of independent motion—how the constant velocity in the horizontal (x) direction and the uniformly accelerated motion in the vertical (y) direction are analyzed separately. Mastering this unit will significantly improve your ability to model and predict the path of objects like thrown balls or launched rockets!
What You'll Learn
Understanding Projectile Motion is a vital step toward achieving a more sophisticated physical analysis. By the end of this lesson, you will be able to:
• Define Projectile Motion and identify real-world examples (e.g., objects launched into the air).
• Identify and practice listing the key assumptions made when analyzing projectile motion (e.g., constant acceleration due to gravity, flat Earth).
• Apply the concept of Independence of Motion to resolve the initial velocity ($\mathbf{v}_0$) into its horizontal ($v_{0x}$) and vertical ($v_{0y}$) components using trigonometry.
• Discuss the essential characteristics of motion in the horizontal direction ($\mathbf{a}_x = 0$ and constant velocity).
• Use the principles of kinematic equations to describe the position and velocity of a projectile at any time ($t$), setting the stage for calculating range and maximum height.
This video is perfectly aligned with the Grade 12 Physics curriculum for Ethiopian students preparing for university-level science and engineering.
