At four he is the highest, with the most potential energy, when he reaches 3 he will have the most kinetic energy as he is in the process of turning all the potential energy to kinetic, as he reaches 3 and 2 he loses all the kinetic energy, when he is at one, and not in motion ha has only potential nergy that is un-used.

The skater will have the maximum kinetic energy at POINT 3.

Conservation of energy.

  • The basic concept behind the question is the conservation of energy.
  • According to the law of conservation of energy, energy can neither be created nor be destroyed. It always remains constant.
  • Therefore, Kinetic energy + Potential energy = constant
  • The kinetic energy that is lost when a body slows down when ascending against the pull of gravity is turned into potential energy, or stored energy, which is then converted back into kinetic energy when the body accelerated upon returning to Earth.
  • When the skater is at the top (at position 1), all the energy is stored as potential energy and kinetic energy is zero at that point.
  • When the skater skates back to the lowest point (position 3), all of its potential energy is converted to kinetic energy. Kinetic energy is maximum at this point.
  • At every point in time, the sum of total energy remains constant.
