In physics, quadratic equations appear naturally in kinematics, especially in constant acceleration motion. The position equation x(t) = at² bt c describes projectile motion, free fall, and vertical motion under gravity. The parabolic trajectory of a thrown object is a direct result of quadratic relationships between position and time. Concepts like maximum height, time of flight, and range are found using the vertex of a quadratic function. Quadratics connect algebra to real-world physics appli
