Looking at the Macro Level Universe (large objects):
1. Gravity
2. Magnetism
and in that order of effectiveness.
Objects start moving when a force is applied to them, such as a push or pull. Objects stop moving when the forces acting on them become balanced, resulting in equilibrium. This can happen when an external force is removed or when other opposing forces come into play.
False. Forces can also set stationary objects in motion.
Forces exist whether there are people, animals, and plants or not. Science just looks at how forces work, and how they relate to movement, acceleration, velocity, work, power, and so forth. So it is not a question of if 'we need scientific forces', at all.
YES
No, gravity and magnetic forces are not the same. Gravity is a force of attraction between objects with mass, while magnetic forces are due to the presence of moving electric charges. Gravity acts on all objects with mass, while magnetic forces act on objects with electric charge.
They are just sitting there, moving and changing according to the forces that are acting on them.
Forces don't move. Objects move. All moving objects have momentum as well as kinetic energy.
While there is some seemingly random movement, in general the objects are moving away from one another. In other words, the Universe is expanding.
Objects that move around other objects in the universe are said to be orbiting it, or in orbit.
When all forces are balanced, the object can either be moving at a constant velocity or be at rest. But because you asked for balanced forces on a moving object, it is moving at a constant velocity.
An object has a general tendency to keep moving - that's how our Universe works. No force is required to keep an object moving - unless there is another force that slows it down. Here on Earth, there are usually frictional forces that slow objects down, and therefore a force is required to counteract the frictional forces.

Red shift means that other objects in the universe are moving away and blue shift means they are moving toward you. This helps to tell where these objects came from, and this knowledge helps predict where they are going to.
