Transfers Between Different Types of Energy

• What is assumed about a closed system regarding energy transfer?

  The maximum amount of energy transfer can be predicted
• How can energy transfer in a closed system be predicted?

  By assuming the maximum amount of energy transfer
• If an object is raised against 500 J of energy, what is the maximum energy allowed to fall back to its starting position?

  500 J
• What happens to energy when an object is raised against a force?

  It is allowed to fall back to its starting position
• What is the maximum energy allowed for a spring when compressed?

  200 J
• How much energy is stored in a compressed spring?

  200 J of energy
• If a spring is compressed and stores 200 J of energy, how much energy can be used to propel an object?

  200 J
• What is the relationship between energy stored in a spring and the energy used to propel an object?

  The energy stored equals the energy used
• What are the implications of energy transfer in a closed system?

  • Maximum energy transfer can be predicted
  • Energy can be stored and released
  • Energy conservation principles apply
• What factors affect the energy transfer in a closed system?

  • The amount of energy input
  • The efficiency of the system
  • The type of energy being transferred
• How does the energy transfer process work in a closed system?

  1. Energy is input into the system
  2. Energy is stored in various forms
  3. Energy is released when needed
  4. Energy conservation is maintained
