When coal is burned to produce electricity, the electrical energy produced is less than the chemical energy stored in the coal.  Which best explains the observations? 

• The amount of chemical energy in fuels is lost.
• Some of the chemical energy stored in coal is converted into forms of energy other than electricity.
• Some of the energy in coal is destroyed by the intense heat required to release its potential energy.
• As coal is heated, some of the molecules move so fast that they are destroyed.

Which student do you agree with more? (6-3A.1)

• Josh says that the little girl has more potential energy at point A because potential energy is greater when the height of the object is greater.
• Julie believes that the point B has more potential energy because that is the point that the little girl is moving the fastest.
• Jaime thinks that the little girl possess the most potential energy at in between points A and B because she is falling.
