Detailed explanation-1: -The book lying on a desk has potential energy; the book falling off a desk has kinetic energy.
Detailed explanation-2: -Explanation: Initially, the book has only potential energy. Right before it hits the ground, all the potential energy will have converted to kinetic energy.
Detailed explanation-3: -A book sitting on a shelf in the library is said to have potential energy because if it is nudged off the shelf, gravity will accelerate the book, giving the book kinetic energy.
Detailed explanation-4: -An object sitting on your desk would have potential energy. The object does not have kinetic energy until it moves in some form or fashion.
