springboard
A "springboard" is a flexible board used in diving and gymnastics that allows athletes to gain height and propel themselves into the air. It is typically made of wood or fiberglass and is mounted on a pivot, enabling it to bend when weight is applied. This bending action provides the necessary force for performers to execute various aerial maneuvers.
In a broader context, the term "springboard" can also refer to any tool or opportunity that helps someone launch into a new phase or endeavor. For example, a scholarship can serve as a springboard for students to pursue higher education, while a mentorship can provide guidance and support for career advancement.
