Answer:
Here is a free body diagram of a book falling off a table:
[Book]
|-------------------|
| |
| |
[Table]
The book is represented by the rectangle. The forces acting on the book are gravity, which is a downward force, and the normal force from the table, which is an upward force. The direction of these forces is indicated by the arrows.
Gravity is the force that pulls objects toward the center of the earth. It is always present and always acts downward. The normal force is the force exerted by the table on the book in the upward direction, in order to balance the force of gravity.
In this diagram, the forces acting on the book are shown as equal and opposite forces. This means that the book is in equilibrium, which means that it is not accelerating. If the book were accelerating, the forces would not be equal and opposite, and there would be an unbalanced force acting on the book.
