From where does the pole vaulter get the energy needed to bend the pole and then rise over the bar hurry plz
Transcribed Image Text:kinetic energy. It trau
he air and the kinetic energy became gravitational poten
che coin rose. At its peak, the coin stopped
momentarily. It now had no kinetic energy, but
did have gravitational potential energy. As the
coin began to fall, it gained kinetic energy as it
lost gravitational potential energy. At all points
during the rise and fall, the sum of the kinetic
energy and gravitational energy of the coin
was constant.
The pole vault is another wonderful example of
the law of conservation of energy. The forms of
energy are changed, or transformed, from one
to another during a vault, but, in principle, the
total amount of energy in the system of the
vaulter and the pole remains constant.
