To calculate the speed of a falling object in water, use the formula: Speed = √(2 × gravity × height), where gravity is approximately 9.8 m/s². This formula estimates the speed when air resistance is negligible. The height refers to the distance the object falls from. Keep in mind that real-world conditions like water resistance may impact the actual speed.
