Physics Of Pole Vaulting By Caitlan Swyer
Linear Motion The more you accelerate the more speed you gain the more height you will gain to get over the top of the pole.
Newton’s First Law Newton’s First Law is defined as an object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. In laymen's terms, this means that anything that starts moving will keep moving until forces such as gravity, wind or friction interfere. Pole vaulters use the energy they create from sprinting into the energy required to overcome gravity and reach their desired height. Thus, the faster you sprint, the higher you should be able to vault.
Newton’s Second Law The greater the force the athlete exerts at take-off the greater the acceleration and height or distance achieved. Once the athlete has left the ground nothing he does will accelerate the body. When maximal forces are needed the muscles contract to generate this force and this is why injuries are more likely to occur in the acceleration or deceleration phases of a movement.
Newton’s Third Law "To every action there is an equal and opposite reaction.“
Impulse/momentum relationship (F∆t= m∆v)
Gravity - weight
Potential and Kinetic Energy Through the proper use of the pole vault, the energy of motion associated with the sprint is converted into the energy needed to overcome gravity and reach a certain height. The energy of motion is called "kinetic energy," while the energy associated with working against gravity is called "gravitational potential energy." The faster you can sprint toward the bar, the higher you can vault over the bar, again assuming a proper technique.
Energy conservation through conversions from one type to another Pole vaulters use the energy they create from sprinting into the energy required to overcome gravity and reach their desired height. Thus, the faster you sprint, the higher you should be able to vault.
