Wasted Energy

• What is the efficiency of energy transfer in real-life systems?

  Not 100% efficient
• Why is some energy always lost in systems?

  Because it is transformed into less useful forms
• What term describes energy that is lost in systems?

  Wasted energy
• What happens to energy when moving objects interact in a system?

  Energy is transferred to heat
• How does energy transfer relate to heat loss in systems?

  Energy is transferred and eventually lost as heat
• What can energy loss in systems be reduced by?

  Lubricating components
• How does insulation affect energy loss in systems?

  It helps avoid heat loss
• What methods can be used to reduce energy loss in systems?

  • Lubrication of moving parts
  • Insulation of the system
  • Reducing friction in components
• What is the ultimate fate of energy in a system?

  It is lost to the surroundings
• Why is it important to consider energy loss in systems?

  To improve efficiency and reduce waste
• What role does friction play in energy loss within systems?

  Friction increases energy loss as heat
• How can reducing friction affect the performance of a system?

  It can enhance efficiency and reduce heat loss
