A book is pushed off a table,and it falls to the floor.Which of the following statements about the book is false?
A)Its potential energy is at a maximum just as it leaves the table
B)Its kinetic energy is at a maximum just before it hits the floor
C)Its kinetic energy is equal to its potential energy at a point halfway between the table and the floor
D)Its potential energy is reduced
E)All of the above are true

All the statements provided are true regarding the book's energy transition from potential to kinetic as it falls. At the start, when the book is on the edge, its potential energy is at its maximum because it's at its highest point relative to the floor. As it falls, this potential energy is converted into kinetic energy, which reaches its maximum just before the book hits the floor. Halfway down, the potential and kinetic energies are equal because the book has lost half of its potential energy to gain kinetic energy, and finally, the potential energy is indeed reduced as it is converted into kinetic energy during the fall.
