A book is at rest on a flat table a person gives the book shelf and it’s nice across the table the book eventually comes to rest again near the edge of the table how does the potential of kinetic energy change during the process

Answer 1

When the book is at rest on the table, it has potential energy in the form of gravitational potential energy. As the person gives the book a gentle push, it begins to move and its potential energy is converted into kinetic energy, which is energy of motion.

As the book slides across the table, its kinetic energy increases and its potential energy decreases. When the book eventually comes to rest near the edge of the table, its kinetic energy decreases and its potential energy increases again, as it is now further from the ground and has the potential to fall off the table.

Overall, the potential and kinetic energy of the book change throughout the process of it being pushed across the table, but the total energy remains constant, as energy is conserved in the system.
