Things that happen internally can make an object turn in place,
but they can't make it move from one place to another.
Two forces that can make an object move are external forces, such as pushing or pulling it, and gravitational forces acting on the object.
Friction force
A balanced force acting on an object at rest does not cause any motion because the forces cancel each other out. On the other hand, an unbalanced force on an object at rest will cause the object to start moving in the direction of the greater force.
If the object doesn't move, the forces HAVE TO be balanced. There is no other way.
The forces are said to be static.
I suppose the forces may crush the object, but they won't move it.
the forces move
-- An object may be in motion even without any forces on it.-- An object will accelerate if the forces on it are unbalanced.
An object can still move even if the action and reaction forces are equal because they act on different objects. The equal forces produce opposite accelerations on the two objects, causing them to move in opposite directions. This is described by Newton's third law of motion.
If forces act on an object but it does not move, then these forces are said to be balanced. This means that the forces are equal in magnitude and opposite in direction, resulting in no net force acting on the object.
Complementary forces are pairs of forces that have equal magnitude but act in opposite directions. These forces balance each other out and do not cause the object to accelerate. An example is tension and gravitational force acting on a hanging object.
True. If two forces are acting on an object in the same direction, they will combine to produce a greater force, causing the object to move in that direction. If the forces are in opposite directions but not balanced, the object will still move in the direction of the greater force.
