I hope that this will provide a possible answer theage old question that echos throughout classrooms: Whenwill I ever use this in the real world? some BackgroundSpringboardHorseRunwayPhysics inGymnasticsRachel LewisSome BackgroundForcesEnergyMomentumRotational MotionVaultingIVaulting is a component of both men s and women sgymnastics run with maximum speed toward the vaultand then drive their legs into a springboard.
