Rolling is a movement technique where an object or person turns over and over along a surface. This can be seen in various activities, such as when a ball is thrown or when a person performs a somersault. The motion relies on gravity and momentum, allowing the object to continue moving until it encounters resistance. In sports, rolling is often used in games like soccer or basketball, where players may roll to avoid being tackled or to gain better positioning. Additionally, rolling is a fundamental skill in activities like gymnastics and parkour, where athletes use it to safely transition between movements.
