Nehru Nagar is a residential area made by Siddhant and Saurabh. Their document discusses projectile motion through defining its components, equations of path and motion, time of flight, maximum height, horizontal range, and examples like cannon balls. Projectile motion results from independent horizontal and vertical motions. The path is a parabola defined by equations combining the horizontal and vertical components. Time of flight, maximum height, and horizontal range can be calculated from initial velocity and launch angle.
