Energy often changes from one form to another. For example, the drummer transfers motion to sound energy. When the moving drumstick strikes the drum head, the drum starts to vibrate. The motion of the vibrating drum head creates the sound you hear. Any form of energy can change into any other form. Frequently, one form of energy changes into two or more different forms. Have you ever sat in front of a campfire? What are two things you notice? The fire creates light. It is also warm by the fire, meaning it creates heat. The energy of the fire comes from the stored energy in the wood. The wood contains chemical energy. As it burns, the chemical energy is changed into light and heat. Not all chemical energy changes produce light and heat. Our cars use gasoline as a fuel. Gasoline contains chemical energy. When our cars burn gasoline in their engines, it is converted into motion and heat. When energy changes forms, energy is conserved. 

Question: "How is burning wood in a campfire different from burning gasoline in a car?"

Response: "The chemical energy in wood burned in a campfire is converted to light and heat whereas in a car, the chemical energy in gasoline is converted to motion and heat"

 Late on the next Sunday afternoon Gifford had gone for a country walk which he had arranged to bring him round in time for the evening service at the little village church of Wynford standing just outside the park boundary.  His way took him by well-remembered field-paths which, although towards the end of his walk darkness had set in, he had no difficulty in tracing.  The last field he crossed brought him to a by-road joining the highway which ran through Wynford, the junction being about a quarter of a mile from the church.  As he neared the stile which admitted to the road he saw, on the other side of the hedge and showing just above it, the head of a man.  At the sound of his footsteps the man quickly turned, and, as for a moment the fitful moonlight caught his face, Gifford was sure he recognized Gervase Henshaw.  But he took no notice and kept on his way to the stile, which he crossed and gained the road.  As he did so he glanced back.  A horse and trap was waiting there with Henshaw in it.  He was now bending down, probably with the object of concealing his identity, and had moved on a few paces farther down the road. 

Question: "How far was the junction from the park boundary?"

Response: "The Junction was about a quarter of a mile from the park boundary"
