A group of forces on an object is balanced when the sum-total of all the individual
forces ... their strength and their direction ... is zero. That means that they all
exactly cancel, and have the same effect on the object as if there were no force
on it at all.
Examples:
-- I push a shopping cart forward as hard as I can, while you use one pinky finger to
push it backward with exactly the same force. The result is that it doesn't move at all.
-- Two members of the varsity football team each pull one end of a rope toward
the north with a force of 200 pounds, while all 40 cheerleaders line up and pull the
other end of the rope toward the south with a force of 10 pounds each. Just like
the shopping cart, the rope doesn't move at all.

What does net force and balanced forces mean?
In the most general situation, net force on an object causes the object to accelerate in the direction of the net force. Under specialized conditions, net force might enable the sportsman to lift the exhausted fish gently out of the water, or it might reflect the inept serve back in the direction from which it arrived.
How can an object have forces acting on it but not accelerating?
If all forces in all direction on an object are equal then a box diagram would show that the forces (newtons, N) will cancel each other out, so it will stay fixed in it's positionIf the forces are imbalanced then you can achieve acceleration. So for a car to move it must overcome tyre friction, so heat and noise wastage, air resistance, and all the smaller forces trying to stop the engine moving (mostly friction). Once it produces more force than those require it can move.No. A balanced group of forces has the same effect on an object as no force at all.
Does newtons second law explain how an unbalanced force on an object causes it to accelerate?
Newton's secong law indicates that an object accelerates in the presence of a net force on it. But it doesn't mean that an object should accelerate when two forces act on it. It depends more on the orientation or direction of force. Say if 2 forces act in opposite directions then the net force would be 0 and thus no acceleration is caused. Hence take NET FORCE, not just force acting into consideration.
Which does not change when an unbalancd force acts on object?
If you mean an external force when you say unbalanced forces, yes. Newton's First Law of motion is also known as law of inertia. Inertia is the movement of mass with out any external forces or influences acting on that mass.
What effect will balanced force have on a book?
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).
To start or change the motion of an object do you need unbalanced force or balanced force?
Doesn't matter Balanced Force would mean the object is traveling at a constant velocity due to Newton's First Law of Motion (Law of Inertia) Unbalenced Force would mean the object is accelerating (or decellerating) due to Newton's Second Law of Motion
What happens when balanced forces act on an object that is at rest?
When an object is subjected to balanced forces, it will continue to maintain its state in motion or at rest. By balanced forces we mean forces that are equal in magnitude but opposite in direction so they cancel each other out. Understanding the concept of speed, velocity, displacement, vector diagram is very important to able to figure out the effect of balance/unbalanced forces on an object.
What are examples of balanced force and unbalanced force?
Examples: Balanced: Two kids are playing tug of war. They are both exerting 4 Newtons of force. (Balanced forces=0 Newtons) Unbalanced: Two kids are playing tug of war. One kid is exerting 6 Newtons of force, the other is exerting 7 Newtons of force. (Unbalanced forces=1 or more Newtons difference[7N-6N=1N) Just because the forces are balanced, doesn't mean that they have to be less than the unbalanced forces. N=Newton
What does an unbalanced force mean?
It means that the total force, when added as a vector, is not zero. Unbalanced forces will cause a mass to accelerate, while a balanced force will keep it at rest (or in motion at constant velocity) without acceleration.
What does unbalanced mean?
Ubalanced force: is when two forces are acting on an object results in a net force and causes a change in the object's motion.
What does Unbalanced force mean?
Ubalanced force: is when two forces are acting on an object results in a net force and causes a change in the object's motion.
What does the term balance mean?
If you add up all the forces acting on an object, they are balanced if they equal zero. (They cancel each other out). If the forces acting on a object are balanced, then the acceleration of that object is zero. It may still be moving, but it is not accelerating. An object that is not accelerating, (the sum of the forces acting on it is zero), is in equilibrium.
When a the net force is zero the forces on an object are balanced?
Correct, the vectors of all forces summed equaling zero mean the forces are balanced, though it could be argued that an object with no forces acting on it has zero net forces, but it's rather hard to balance nothing with more nothing,
How will you know whether the given applied force on an object is balanced or unbalanced?
You must firstly know it's physical details and it's conditions (The objects'). If you apply a balanced wave of force it will maintain those physical details and conditions but if you apply an unbalanced wave to the object it will suffer from maintaining it's physical details and conditions. Also when the object is not moving or when the object is moving at a constant velocity and if at it's moving it doesn't have any changing velocity (Acceleration) it will mean the applied force is balanced. Other than this, is unbalanced.
How do balanced and unbalanced forces effectThe direction forces act?
Balanced forces mean that the net force is 0, and so there is no net direction of the force. This results in no movement. When unbalanced forces are acting on an object, the net force points on the direction of the resulting vector that arises from vector addition and subtraction. Think of a game of tug of war for example. If one team has 10 men, and the other has only 5, then the rope will move towards the 10 men because they exert more force (unbalanced), and move the rope towards them. If there were 10 men on each side, the direction would be towards both simultaneously, and so no movement would occur.
Are net force and balanced forces the same?
Balanced forces mean the net force is zero, so they are not the same unless net force is zero. Net force is the vector sum of all forces on an object
What does forças desequilibradas mean?
Unbalanced forces.
