Chapter F, Problem A.5AST

Interpretation Introduction

Interpretation:

Gravitational potential energy of book has to be calculated.

Concept Introduction:

Potential energy is the energy that is possessed by an object due to the position of the object in field of force.  Potential energy is represented as ${\text{E}}_p$.  The expression for potential energy is given as shown below;

    ${\text{E}}_p=\text{mgh}$

Where,

    $\text{m}$ is the mass of body.

    $\text{g}$ is the acceleration due to gravity.

    $\text{h}$ is the height above the Earth surface.
