Answer:
Example Item Description of potential-kinetic energy conversion
Example Book The book had potential energy when it was on the table. Then as the book fell off the table, it was in motion and had kinetic energy.
1 ball The ball had potential energy because it was in one place. Then it rolled off the counter and it was kinetic energy.
2 Paper airplane The airplane was sitting on the table in had potential energy until I picked it up and threw it which made it kinetic energy.
3 Chips Chips were in the closet sitting on the shelf which is potential energy and one fell of the shelf which made it kinetic energy.
4 Clock I put my clock on the wall which is potential energy and then a few days later it fell off which is kinetic energy.
5 water I had water sitting in a cup which is potential energy the I grabbed it and spilled which makes the water kinetic energy.
