Task: Story Composition
Input (English): Background Paragraph: There are two basic types of energy in the universe: potential energy and kinetic energy. Potential energy is stored energy that is available to do work, but it has not yet been released. The wood in a fireplace possesses potential energy. It is available for producing heat, but has not yet been ignited, so it is not releasing heat into the surrounding environment. Kinetic energy is the energy of motion. A waterfall is an example of kinetic energy. The moving water can erode the rocks in the stream, wearing them down into smaller particles. This same water motion can turn a turbine to generate electricity. In both cases, the movement of the material (water) causes work to be done.
Output (English): While out on a hiking trip Ricky stumbles upon a waterfall. While looking at it he notices that the rocks around and behind the waterfall as well as the rocks in the stream it flows into are smooth, When he is no longer near the waterfall the rocks are very jagged and cracked and sharp.
