Projectile Motion: Trajectory Analysis

This lecture covers the analysis of projectile motion, focusing on the trajectory of objects in free fall. Starting with examples of uniformly accelerated motion, the instructor explains the parabolic path of projectiles and the key criteria for determining maximum height and horizontal distance. The lecture progresses to discuss the angle of launch for a projectile to reach a specific point, the time of flight, and the horizontal distance traveled. Special cases are examined, such as objects passing through a point with constant acceleration. The principles of inertia and the concept of inertial reference frames are also introduced, emphasizing the conditions for an object to move in a straight line at constant speed.
