To think of forces acting on an object we must first make one very important decision, and that is to define our point of observation. This is important because the frame of reference will tell us how an object is moving in relation to us and determine which one is to be viewed as an unbalancing force.

For example, one theory of the creation of our Moon is that about 4.6 billion years ago a protoplanet called Theia crashed into our ancient Earth. Both of these protoplanets were in orbit around the sun and in balanced motion. When the collision occurred it would depend on which one of the two, Earth or Theia, you happened to be standing on and observing what was happening to be able to form an opinion as to which one was the 'unbalanced force.' If you were on one, you would have most likely choosen the other.

For Newtonian physics, most things are a two body problem, that meaning that only two objects are considered at a time. If we consider that everything in the Universe is in constant motion, then we can look at all forces, if combined, are actually keeping things in balance.

Again, let me restate what I said earlier, an unbalanced force can only be determined if we have a point of reference and are talking about only two objects.

Is change an object's motion balanced or unbalanced force?

A change in an object's motion can be caused by both balanced and unbalanced forces. Balanced forces result in no change in motion, while unbalanced forces cause acceleration or deceleration in the object's motion.


How do unbalanced forces acting on an object its motion?

Balanced forces do not change its motion (no acceleration). Unbalanced forces changes the motion of the object (acceleration).


How do balanced forces acting on an object affect its motion. How do unbalanced forces acting on an object affect its motion?

Balanced forces do not change its motion (no acceleration). Unbalanced forces changes the motion of the object (acceleration).


What is true about the motion of an object if the forces are unbalanced?

If the forces acting on an object are unbalanced, the object will accelerate in the direction of the larger force. This acceleration will continue as long as the forces remain unbalanced. The object's velocity and direction will change in response to the unbalanced forces.


How do unbalanced forces acting on an object affects it's motions?

Balanced forces do not change its motion (no acceleration). Unbalanced forces changes the motion of the object (acceleration).


Will unbalanced forces acting on an object change its motion?

An unbalanced group of forces on an object causes the object to accelerate.Its acceleration is (the vector sum of all the forces)/(the object's mass) .


Is change in anobjet's motion anunbalanced force?

Not exactly. 'Motion' or 'change of motion' are not force. But the only way to change an object's motion is to cause the group of forces on it to be unbalanced. If the object's motion is changing, then you can be sure that the group of forces acting on it is unbalanced.


What motion does an object have if forces are unbalanced?

If forces are unbalanced on an object, the object will experience acceleration in the direction of the net force. The motion of the object will change depending on the direction and magnitude of the net force applied.


What does apply forces to object balanced vs unbalanced?

Applying balanced forces to an object means the forces are equal in size and opposite in direction, resulting in no change in the object's motion. Applying unbalanced forces means the forces are unequal, leading to a change in the object's motion, such as acceleration or deceleration.


Describe the difference between balanced and unbalanced forces?

Balanced forces have the same effect as not moving at all. The motion of the object does not change at allOnly unbalanced forces can change the motion of an object. It does not matter if the object was at rest or was already moving.


Which cause change in motion balanced forces or unbalanced forces?

Unbalanced forces cause a change in motion by accelerating an object in the direction of the greater force. Balanced forces result in no change in motion since they cancel each other out, resulting in a state of equilibrium.


What do unbalanced forces do to an object motion?

Unbalanced forces cause a change in an object's motion by either speeding it up, slowing it down, or changing its direction. The object will accelerate in the direction of the greater force.
