Define balanced force?
There's no such thing as one single balanced force. A group of two or more forces are balanced if they all add up to zero. Like if two people are pushing on the same shopping cart ... one in the back pushing it forward, and one on the front pushing it backward. They add up to zero, and the cart acts exactly as if there are no forces on it at all ... it stands still. Those two forces are balanced.
How does gravity affect the balanced and unbalanced force?
gravity is definitely a balanced force
If forces are unbalanced is there acceleration?
yes, since the forces are acting on just one body, the mass (m) in the equation F=ma is not changing, which would mean that the two accelerations (a) would have to be different. If the two accelerations are different then there is total acceleration in one direction (the resultant acceleration).
Does an object possess force?
When drawing a free body diagram, it is incorrect to draw any forces an object exerts on itself.There are several forces that can be confused with an object exerting force on itself, such as the force of gravity and the various forces involved in structural integrity.The various parts of a large machine or other physical thing certainly can exert force on each other.For example, a typical flashlight has a spring that presses against the batteries with some force, and the other end of the batteries press against a metal contact with roughly the same force.However, all such forces are balanced. The net force on the object as a whole is always zero, so the net acceleration to the center of mass caused by such forces is always zero.So when you only care about the object as a whole and how it interacts with external objects, you draw it as a single object in the free body diagram and ignore all such internal forces, since their total net force is zero.When you do care about internal forces of a large physical object, for example the structural integrity of a bridge, you draw each part you are concerned about as a separate object in the free body diagram.Perhaps you will draw each strut in a bridge truss as a separate object.With such a more detailed diagram, one can calculate the forces between parts of the bridge, and find the appropriate size strut and bolt to handle those forces.The extreme case of dividing up a large physical object into smaller parts on a diagram is called finite element analysis (FEA).People doing finite element analysis make free body drawings that show "objects" that correspond to small, in some cases microscopic, regions of a solid strut or bolt.Some science fiction writers describe spacecraft that somehow "pushes itself" from one place to another, using "reactionless propulsion".But as far as we know now, all such devices are purely fiction. All known methods of moving a person from one place to another require forces on some external object.Walking and taking the train push directly against the Earth; airplanes push air down and back to provide lift and thrust; rockets push propellant out the rearward-facing end of the rocket, etc.
Does a force always cause things to move?
You need to look at the net force... which is the resultant of all the forces... if there is a net force then there will be an acceleration and therefore the object will move.. however there can be many forces acting on a single object but as long as those are in equilibrium then the object will not move... so to answer your question: a force does not always cause things to move... also.. a thing can be moving without a force... see newtons first law..
What is the difference between balanced forces and action and reaction forces?
"Action and reaction" refers to Newton's Third Law. Forces always come in pairs; if object "A" pushes against object "B", then object "B" will push back against object "A". Which of these two forces is called the "action", and which the "reaction", is often arbitrary."Balanced forces" is unrelated to the above; when forces are "balanced", it means that the vector sum of all the forces that act on the same object are zero. Please note that "action and reaction" forces are forces that act on different objects, so the forces on a single object are not necessarily balanced.
Is pushing a box but it doesnt move a balanced or unbalanced force?
There's no such thing as a balanced force or an unbalanced force.If the entire group of all the forces on an object is unbalanced, then the objectundergoes acceleration, or its "motion changes". If the group of forces on it isbalanced, then its motion doesn't change.
Explain the difference between balanced forces and actionreaction forces?
Balanced forces do not change because each side is pushing the other with the same amount of force. Action Force is a force that exerts a force on another object.Reaction force is equal, and opposite of the first force. In response to the force applied.Hope that helps
Balance forces have what affect on an objects motion?
"Balanced forces" means a set of forces that add up to zero.This group of forces acting on a single object have no effect on its motion, because they add up to zero,and their effect is equivalent to zero force on the object.

Do unbalanced and balanced forces have directions in which they travel?
Every force has a direction. Two or more separate forces acting on the same object have thesame effect on the object as a single force. The strength and direction of the equivalent singleforce can easily be calculated, and may not be the same as the strength or direction of any of theindividual forces.

What really are balanced forces?
A balanced force is when two equal forces are applied on an object pushing both ways. Also they are equal forces acting on an object in opposite directions.When something isn't moving the forces are balanced, eg. Gravity pulls a table down but that table is pushed up by the floor or the ground it stands on so doesn't move.An UNbalanced force is needed for something to change movement or change direction, eg. a seesaw moving up and down because the forces aren't equal.A balanced force is a force equally opposed by another force in the opposite direction, meaning that they cancel out each other so the object does not move, unlike an unbalanced force, where the object will move because one force over powers the other.When something isn't moving the forces are balanced, eg. Gravity pulls a table down but that table is pushed up by the floor or the ground it stands on so doesn't move.An UNbalanced force is needed for something to change movement or change direction, eg. a seesaw moving up and down because the forces aren't equal.Unlike balanced forces, we say unbalanced forces when two forces acting on an object are not equal in size.When a number of forces act on a body simultaneously and the resultant of these forces is zero, then the forces are said to be balanced.Moment=distance from pivot to source of force x forceNm= m x NMoments on either side of an object must be equal for the object to balance.e.g on a see-saw someone who weighs 1000N sits 1m from the pivot, and someone who weighs 2000N sits 0.5m from the pivot on the other side of the see-saw will balance as in this situation, on both sides of the see- saw Nm=1000A balanced force is where forces on opposite sides of the object are the same net force (for example, 15 N and -15 N) which makes for the object being at rest. Balanced net force on an object makes for the object ALWAYS being at rest. Also it has to be even on both sides to be a balanced force -Keyaira PennieBalanced forces do not cause a change in motion. They are equal in size and opposite in direction.
What causes a change in motion a balanced or unbalanced force?
Forces on a moving object are balanced only when the object is moving at a constant velocity. Remember, acceleration is a force and a constant velocity is equivalent to zero acceleration. Think of a ping pong ball that you drop from a few meters above the ground: After a short acceleration the ball reaches "terminal velocity" when the air resistance balances the gravitational acceleration. After this, the forces on the ball are balanced (although it is moving, the velocity - speed & direction - of the ball is not changing)
What is the difference between a balanced force and an unbalanced force?
An example of a balanced force is two cards leaning against each other and not falling over, or two football players blocking each other but neither overpowering the other. An example of an unbalanced force is two cards leaning on each other then falling over, or two football players blocking each other, then one tackles the other.
A force that does not touch?
The only way a single force can fail to change an object's motion isif the magnitude of the force is zero.(Don't go off on a tale of a "balanced force". There's no such thing as a balanced force.Groups of forces can be balanced. The forces themselves can't.)
What is a single force that has the combined effect of all the forces acting on an object called?
Resultant
