The force of gravity causes a book to fall, but someone has to push it to the edge of the desk, or off the desk so that the force of gravity is greater than the normal force acting on the book.

∙ 11y ago-- A book is not a force.
-- There's no such thing as "a balanced force".
-- If the book is accelerating, then the group of forces acting on it is unbalanced.
-- When the book falls from the table, it accelerates until it encounters the floor.
So while it's falling, the group of forces acting on it must be unbalanced.

∙ 7y agoEarth is pulling the book down, with the weight of the book.Since the book is pushing down on the table (same force as above), the table pushes back up (Newton's Third Law).
The two forces acting on the book - Earth downwards, table upwards - add up to zero.

A box is sitting on a table. The upward force exerted on the box that stops it from falling through the table is known as the force.?

Which of these would you include in a free body diagram of a coin balanced on its edge on a table?
The force of gravity acting on the coin.
To stop the table in your class falling through the floor what must the floor do against the force of gravity pulling the table down?
The floor must exert a force equal to that of the force exerted on the desk from gravity. This force is called a "normal force"
What is an example of a balanced force acting on an object?
Take the example of a book resting on a table. The downward force of the book's weight is matched exactly by the upward resistance of the table - hence the book remains where it is. (If the table was very flimsy, and unable to support the weight of the book, the book would accelerate towards the ground.)
Equal and opposite forces that do not produce an acceleration?
A book setting on the table. The force of gravity is balanced by the equal and opposite force of the table holding the bookk. No acceleration of the book due to those forces.
Is a textbook on a table a balanced force or an unbalanced force?
A textbook on a table is an example of balanced forces. The force of gravity pulling the book downward is balanced by the normal force exerted by the table in the upward direction, resulting in the book remaining stationary on the table.

What force stops a plate falling through the table?
The electromagnetic forces holding molecules together within the table provide a mesh like structure that prevents the molecules of other objects protruding (or falling) through it!
To stop a table falling through the floor in your classroom what must the floor do against the force of the gravity pulling th table down?
Push it up.
To stop a table in your classroom falling through the floor what must the floor do against the force of gravity pulling the table down?
Newton's third law of motion states that: "For applied force (A), exists some force (B) of equal magnitude acting in the opposite direction of the force applied.". The force of the weight (which is the mass of the table multiplied by gravity) [W=mg] pushing down on the floor is counterbalanced by an equal and opposite force of the floor pushing up on the table. This is why the table does not fall through the floor. The floor is able to provide this force without allowing the table to move through it because the bonds between its atoms are strong enough.
What are similarities between balanced forces and action reaction forces?
There is no such thing as a balanced force or an unbalanced force. A groupof two or more forces may be balanced or unbalanced. The group of forces isbalanced if the vector sum of all the forces in the group is zero.
Think Critically A book sliding across a table slows down and comes to a stop Explain whether the forces acting acting on the book are balanced or unbalanced.?
The forces are unbalanced. The force of Friction is obviously greater than whatever force is pushing the book in the direction of travel, if one is pushing it at all. If the forces on the book were balanced, the book would continue to slide with a constant velocity.
Why wont a book resting on a table fall to the ground What forces are acting on the book?
The book will not fall to the ground because of the force of gravity pulling it down and the normal force exerted by the table pushing it up. These two forces are equal and opposite, resulting in a balanced system where the book remains stationary.
