What you'll learn

Key ideas in The Secret Life of Energy

  • Energy is required to change an object from being still to moving
  • A push from a new direction changes the object's path
  • A change in speed is a visible sign that energy was transferred
  • Moving objects don't just stop when pushed sideways; they redirect
  • Recognizing that a change in motion is evidence of energy transfer
  • Predicting the result of a push from a different direction
  • The strength of a push determines how much energy is transferred
  • The direction of a push determines if an object speeds up or slows down
  • Mapping specific actions to their effect on an object's energy and motion
  • Heat energy always moves from the warmer object to the cooler one
  • Heat travels through solid materials via conduction
  • Energy transfer continues until both objects reach the same temperature
  • Energy moves from the hot end of an object toward the cooler end
  • Difference in temperature triggers energy movement
  • The direction of heat flow between objects of different temperatures
  • Heat flow stops once temperatures are balanced
