How Momentum Play A Role In A Gymnast

In gymnastics, both men and women compete in the vault. This is an event where a gymnast runs full speed towards a springboard on the ground, is then propelled through the air onto a table (sometimes referred to as a horse), and then through the air again before landing on a mat. The vault is one of the most difficult events in gymnastics because it requires a great deal of force created by the gymnasts in a short period of time. In this paper, I will be analyzing the physics behind the vault. I will discuss the energy used through the event and also how momentum plays a role in a gymnast’s success.
Energy
The first thing a gymnast does during the vault is run 25 meters down the runway towards the springboard. During this time, the gymnast …show more content…

The more the gymnast can get the springboard to compress, the more potential spring energy they will produce. This is important because this potential energy is needed to push the gymnast up onto the table. This can be further explained through the work-energy theorem. This theorem explains how the work the gymnast does on the springboard is equal to the change in kinetic energy. In summary, the more the gymnast is able to compress the spring, the more kinetic energy is transferred back into the gymnast as they leave the …show more content…

This is important because due to the conservation of momentum, as soon as the gymnast is launched into the air, they are unable to gain anymore angular momentum. A large angular momentum is needed for a gymnast to produce more twists and spins in the air.
A way for a gymnast to maximize the amount of angular momentum they have is by decreasing the distance of their body from their axis of rotation while in the air. A gymnast’s axis of rotation is near their hips so to decrease the distance of their body from their hips, they have to tuck their body into a ball. This positioning of their body allows them to spin faster, increasing their angular velocity, while they are in the air. This also increases the amount of torque on the gymnast’s body. The more torque that the gymnast has, then the more rotation they will be able to achieve thus also increasing their angular velocity. When the gymnast is ready to land, they extend their body so that they slow down making it easier to land on their
