Car Design

• What type of energy do car engines convert to enable movement?

  Chemical energy to kinetic energy
• How does the engine contribute to the movement of a car?


  The engine does work on the car to move it forward
• What must the engine continually do to keep the car in motion?


  The engine must continually do work against resistive forces
• What are some resistive forces that oppose a car's motion?


  Friction, air resistance, and drag
• What happens to kinetic energy as work is done against friction and drag?


  Kinetic energy is converted into heat
• Why is driving force always needed in a car?


  To maintain speed and replace lost kinetic energy
• How can streamlining a car's body help in energy conservation?


  It reduces the work done against air resistance
• What causes air resistance when a car is moving?


  Collisions between the car and air particles
• How does streamlining affect energy loss in a car?


  It reduces energy lost to resistive forces and heat
• What is the goal of engine design in terms of energy efficiency?


  To be as energy efficient as possible
• What is the primary input to a car engine?

  Chemical energy from petrol
• What happens to some of the energy input into the engine?


  Some energy is lost to heat and sound
• How does lubrication affect the moving parts of a car?


  It reduces friction between moving parts
• What is the effect of reduced friction in the car's moving parts?


  It leads to less heat loss
• What is a benefit of electric vehicles compared to traditional cars?


  They are more energy efficient with fewer moving parts
• What are the key concepts related to car design and energy efficiency?


  • Energy changes in car engines
  • Dissipated energy and heat loss
  • Steps to reduce energy loss through heat and friction
• Is car design specifically mentioned in the exam specification?


  No, it is not specifically mentioned
