Question

A book is sliding along a desktop. Because the book is in motion, you know that the forces acting on the book are ______? What is the force acting against the book?

Answer 1

Normal force, gravity and Friction.

Step-by-step explanation:

The forces acting on the book are normal formal force which act or exerts by the table on the book while on the other hand, gravity is a force that acts in the downward direction. Friction is the force that acts against the motion of the book and is responsible for lowering speed of the book that is sliding on the surface of the table. If the friction is low between the book and table then the book moves easily on the surface.
