Books can be carried to school without changing the kinetic or potential energy of the books or doing any work: by moving the book without acceleration and keeping the height of the book constant.
<h3>What is potential energy?</h3>
Potential energy can be defined as a type of energy possessed by an object due to its height above the Earth.
In Science, the potential energy and the work done by an object such as a book is highly dependent on its height or position.
<h3>What is kinetic energy?</h3>
Kinetic energy can be defined as a type of energy possessed by an object due to its motion or change in velocity (acceleration).
This ultimately implies that, an object in motion or with an acceleration would possess kinetic energy.
In conclusion, books can only be carried to school without changing the kinetic or potential energy of the books or doing any work when they are moved without acceleration (velocity is constant) and their height is kept constant.
