bungee

• What is meant by the conservation of energy?

  Energy cannot be created or destroyed
• How can energy be transferred within a system?

  Through various energy stores and transfers
• What happens when energy is dissipated?

  It is transformed into thermal energy
• What energy transfers occur when a pendulum swings?

  Gravitational potential energy to kinetic energy
• What energy transfer occurs during a bungee jump when the jumper falls?

  Gravitational potential energy to kinetic energy
• What happens to kinetic energy when the bungee rope starts to tighten?

  Kinetic energy is at its maximum
• What happens to kinetic energy when the bungee rope is fully extended?

  Kinetic energy store is zero
• What energy store is filled when the bungee rope is fully extended?

  Elastic potential energy store
• What happens to energy during the ascent of a bungee jumper?

  Energy transfers back to gravitational potential energy
• Why does the jumper never return to the original position?

  Energy is dissipated as thermal energy
• What causes energy dissipation during a bungee jump?

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

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

  All energy is in gravitational potential energy
