The cause of nationalist forces moving into Shanghai was to establish control over the city and consolidate their power. The effect was increased tension and conflict with the existing communist forces in the region, which eventually led to the Chinese Civil War.
Friction force
Two forces that can make an object move are external forces, such as pushing or pulling it, and gravitational forces acting on the object.
Yes, an object can move at a constant speed if the three forces acting on it are balanced, resulting in zero net force. The forces can cancel out each other's effects, allowing the object to maintain a constant speed.
The forces are said to be static.
Balanced forces
If the object doesn't move, the forces HAVE TO be balanced. There is no other way.
Nebulae can appear to move due to the effects of gas and dust within them being pushed and pulled by various forces such as gravity, radiation pressure, and stellar winds. However, their movement is relatively slow on human timescales.
All forces make things move only if it is bigger than friction or resistance. In a vacuum (e.g. space), all forces make things move. But this is not reality.
the forces move
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.
