There would have to be an unbalanced force put an object in motion but once in motion no force is necessary for it to remain in motion
the unbalanced force would be balance.
In principle, any force acting on an object is unbalanced, UNLESS there is a second force in the opposite direction, acting on the same object.
Unbalanced forces cause acceleration, not movement. An object can move at a constant speed with no net force acting on it. An example would be an object falling at terminal velocity.It would have to have been already moving. Newton's First law states that an object at rest will remain at rest and an object in motion will remain in motion with the same speed and direction unless it is acted upon by an unbalanced force. The second part of the law explains this.
-- An unbalanced group of forces on an object causes the object to accelerate in the direction of the net force. -- If an object is not moving, then the group of forces on it must be balanced, else it would be accelerated.
Yes, due to momentum. For example, an object traveling in space might have no forces acting on it but still be moving through space. However, the question might also be asked, how did this object start moving in the first place? If the object was created in a stationary state, then unbalanced forces would have to act upon it to get it moving. The object would have to have been created while moving in order to get it to move without unbalanced forces acting upon it.
coz if they werent, whatever they were acting on, would either stay sill, or move at a constant speed
If you doubled the force on a moving object you would double its acceleration.
If there are any forces acting on a stationary object, then they must be balanced, or it would no longer remain stationary.It is also possible that the object is already moving. In the forces are balanced on a moving object, the object would continue moving at the same speed and direction (velocity) that it already had.
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).
That means that there are one or more forces acting on an object, but the vector sum of these forces is not zero. That would cause the object to accelerate - in other words, its speed would change.
There's no such thing as "an unbalanced force".When the group of forces acting on an object is unbalanced, then the objectaccelerates, in the direction of the vector sum of the forces.
it is when an object has unbalanced forces and balanced is when an object has equal forces
