bungee jumper

• What is meant by the conservation of energy?

  Energy cannot be created or destroyed, only transformed from one form to another
• How is energy transferred within a system during a bungee jump?

  Energy is transferred from gravitational potential energy to kinetic energy, then to elastic potential energy, and back
• What happens to the energy of a bungee jumper when they fall?

  Gravitational potential energy is converted to kinetic energy
• What is the maximum state of the kinetic energy store during a bungee jump?

  When the bungee rope just starts to tighten
• What happens to the kinetic energy store when the bungee rope is fully extended?

  The kinetic energy store is zero because the jumper is not moving
• What happens to energy when the bungee rope recoils?

  Energy is transferred from the elastic potential energy store back to the kinetic energy store
• During the ascent of a bungee jumper, how is energy transferred?

  Energy transfers from the kinetic energy store back to the gravitational potential energy store
• What happens to all the energy at the top of the ascent in a bungee jump?

  All of the energy is now in the gravitational potential energy store
• Why does the bungee jumper never return to the original position?

  Because energy is dissipated as thermal energy due to friction and stretching effects
• What causes energy dissipation during a bungee jump?

  Friction with air particles and stretching effects in the bungee rope
• What type of energy is always dissipated during the bungee jump?

  Thermal energy
• What are the key energy transfers during a bungee jump?

  • Gravitational potential energy to kinetic energy during the fall
  • Kinetic energy to elastic potential energy when the rope tightens
  • Elastic potential energy back to kinetic energy when the rope recoils
  • Kinetic energy back to gravitational potential energy during ascent
• What are the effects of energy dissipation in a bungee jump?

  • Jumper never returns to the original position
  • Energy lost as thermal energy due to:
  • Friction with air particles
  • Stretching effects in the bungee rope
• Where can you find more questions on energy transfers like the bungee jump?

  In the Vision workbook
• What is the final state of energy at the top of the ascent in a bungee jump?

  All energy is in the gravitational potential energy store
