many people say that a vaulters run up is what is building there potintial energy which is sortof true but in reality however much the pole bends is the potintial energy of the vault
Potential you welcome bro troll
A pole vaulter has kinetic energy as they run with speed, potential energy as they use the pole to propel themselves upwards, and gravitational potential energy as they reach the peak of their jump.
In pole vaulting, the vaulter converts kinetic energy from their run into potential energy as they bend the pole and rise into the air. As the pole flexes, it stores elastic potential energy, which is then released to propel the vaulter upwards. At the peak of the vault, the potential energy is at its maximum before converting back into kinetic energy as the vaulter descends. Overall, the energy transformation is a dynamic interplay between kinetic, potential, and elastic energies throughout the vaulting process.
Elastic Potential Energy
When a pole vaulter's pole reaches its maximum bend point all the energy if the system is being stored as potential energy in the pole. Etotal = PE + KE. At this point KE is 0 so PE=Etotal. However, as the pole straightens out again, the stored PE is released as KE.
When the pole vaulter just passes over the bar, he/she is almost stationary, and certainly at the maximum height reached above the ground, so apart from a very small amount of kinetic energy as a result of passing over the bar, all the energy put into the vault is bound up in gravitational potential energy. During the approach, the jumper runs up so has acquired kinetic energy. Then during the vault he/she exerts force on the pole to gain height, and to convert the horizontal kinetic energy into a vertical direction. This force comes from the chemistry of the muscles of the body. So the overall conversion is from kinetic energy plus muscular chemical energy into gravitational potential energy, which is then converted back to kinetic energy on the descent.

The pole vaulter height model is a mathematical representation that predicts the maximum height a pole vaulter can achieve based on various factors, including their speed, the flexibility of the pole, and the technique used during the vault. It typically involves principles of physics, such as energy conservation and mechanics, to analyze the kinetic and potential energy transformations during the vault. This model helps coaches and athletes understand optimal performance parameters to enhance training and improve vaulting techniques.

Pole vaulter
The energy of the pole vaulter at a height of 4m above the ground will be in the form of potential energy. Using the formula for potential energy (PE = mgh), where m is the mass, g is the acceleration due to gravity (9.81 m/s^2), and h is the height, we can calculate the energy. The potential energy in this case would be 1960 J.
The vaulter may use a pole (under his/her wieght) to go over a cross bar. If the cross bar falls off before the vaulter is off the mat, it is counted as missed. A scratch is when a vaulter's pole hits the back of the box and the vaulter doesn't leave the ground. Besides that it's a unique event considering there are vaulter have many different techniques.
