The forces at work are balanced. Gravity is pulling the book (and the rope) down, and the rope exerts an equal and opposite force to keep the book suspended.
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.
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 ?
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.
If the object doesn't accelerate, then the forces are balanced - meaning that the vector sum of forces is equal to zero. If the object does accelerate, then the forces are unbalanced - the sum of all forces is not equal to zero.What the force are really varies from case to case. In general, there usually is at least the gravitational force acting on an object, and if the object doesn't accelerate, that means there must be at least one other force acting on the object. Here are two examples:A book resting on a horizontal table. Gravity pulls it down. The table pushes the book up.Some object resting on an inclined surface. In this case, the forces to counteract gravity are a combination of gravity and friction forces.
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.
Balances forces revolve around prayers and positive thinking. Keep your private, public, and online life as separate as possible also secures proper balance. In terms on unbalances forces, the lack of inner happiness in countless people is becoming truly overwhelming. This is due to the the ongoing fiscal crisis, economic situation, and the belief that Satan has influenced the evil that has plagued the globe for the last 2-3 years.
My understanding that the unbalanced forces are the ones that push the object in one direction (cause motion), while the balanced forces simply cancel each other out. If I have a book sitting on the table, and equal forces pushing it to the right and the left, it will remain stationary. However, if I apply a third force pushing it down toward the edge of the table, there won't be anything to counterbalance it (except the frictional force from the table), so it will move towards the edge. - Cookie :)
If the forces are balanced, this implies that the net force on the book is 0. Therefore, using Newton's second law, F = ma, F = 0, and since the mass of the book is non-zero, a = 0. This means that the book is not accelerating in the direction of these forces. However, this DOES NOT mean that the book is stationary; it could be travelling at any CONSTANT velocity (since there is no 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.
2 forces are being pushed of pulled in the same direction. (Straight out of my physical science book)
A balanced force is the one in which if there is a force on one side of the object , on the other side there is a force of the same magnitude. example is a book kept on a table is at rest. 2 forces are acting on it. one is vertically downwards that is its weight(mg) while other is perpendicular to he surface(normal force exerted by the table) an unbalanced force is 2 forces acting in opposite directions have different magnitudes and the direction of the object is towards the direction of the dominant force. example is 2 children are pulling a rope one with a force of 100N and other with 50N. rope is pulled by the child applying a force of 100N.
