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.)
Think Critically A book resting on a table slows down and comes to a stop Explain whether the forces acting acting on the book are balanced or unbalanced?
As long as the book's velocity changes, there is a net forces acting on it - in other words, the forces are unbalanced. By the way ... How exactly does a book that is resting on a table slow down and come to a stop ?
Why won't a book resting on a table fall to the ground?
Because the table is exerting an upward force on the book exactly equal and opposite to the force of gravity.
What acts perpendicular to the surface of a book resting on a table and balances the weight of the book?
Reaction force.
Would a book falling off a table be a balanced force?
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.
Does the book on the table have a force acting on it going upwards if no why or yes?
For example, if the book is resting on a table, gravity pulls the book down, and the table pushes the book up.

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.

Why wont a book resting on the table fall to the ground?
Apply Newton's third law of Universal Dynamics. 'To every force there is an equal and opposite force'. The book is applying a downward force., so the table is applying a resistant force upwards, which are equal forces , so the book does not fall.
If a book is placed on top of the table are there forces acting on the book?
Yes. For a start, gravity pulls it down. Also, the table pushes up on the book, thus canceling the force of gravity.
Is gravity the force applied up or down on an object?
Gravity pulls things downwards, so it is pointed downwards. If an object is resting on something (like a book resting on a table) an equal force will point upwards and that force is known as the normal force.
When a book falls off the table it changes into what?
When a book falls off the table, it changes from a state of rest to a state of motion. Gravity is the force acting on the book that causes it to fall.
