Question

identify whether the bold - faced object described below possesses kinetic energy, gravitational potential energy, or elastic potential energy. select all that apply. a physics book is hanging from the ceiling of the room above a students desk. select all that apply. kinetic energy gravitational pe elastic pe

Explanation:

Kinetic energy is energy of motion. The book is hanging still, so it has no kinetic energy. Gravitational potential energy is given by $U = mgh$ (where $m$ is mass, $g$ is gravitational - acceleration, and $h$ is height). The book has mass, is at a height $h$ above the desk, so it has gravitational potential energy. Elastic potential energy is stored in a stretched or compressed elastic object. The book is not an elastic object being stretched or compressed, so it has no elastic potential energy.

Answer:

Gravitational PE
