๐Ÿ“š Quick Study Guide

    ๐Ÿ” Horizontal projectile motion describes the movement of an object projected horizontally and only influenced by gravity. ๐ŸŽ The vertical motion is identical to free fall, with constant acceleration due to gravity ($g = 9.8 m/s^2$). ๐Ÿ“ The horizontal motion has constant velocity (assuming negligible air resistance). โฐ Time of flight depends only on the vertical distance and gravity: $t = \sqrt{\frac{2h}{g}}$, where $h$ is the vertical height. ๐Ÿ“ The range (horizontal distance) is calculated as $R = v_0t$, where $v_0$ is the initial horizontal velocity. ๐Ÿ’ก Key Assumption: Neglect air resistance for simplified calculations. ๐Ÿ“ Remember: Horizontal and vertical motions are independent of each other.
