Certainly it appears that gravity does so.
Presumably the most important force on an accelerating space shuttle is the force of the rocket engines (thrusters). Certainly other forces are present, including gravity and air friction.
almost as much as the shuttle's weight on Earth's surface
A space force is a military branch that prepares for or conducts space warfare. As of January 2020, the only nation with an independent space force is the United States, which established the United States Space Force in December 2019.
When a shuttle reaches outer space it can turn off its thrusters because the law of inertia states that an object in motion can stay at motion until a force acts upon it. And it can just fly without wasting gas/fuel.
It is a force called the thrust and it pushes it into space.
electromagnet
No - gravity acts across the vacuum of space - this is how the moon affects our tides.
time
Impulse - APEX ! =)
Strictly speaking, you would say that a force acts on a system and the impulse of that force corresponds to the change in momentum of the system due to the action of the force. More mathematically, the impulse of a force is defined as the integral of that force with respect to time over the time period that the force acts.
A force which acts continuously at specific intervals of time is called periodic force.
Neither. It's a force. A force of space that acts similar the the pressure of water exerted on an object when in deep waters. Space is the ultimate of deep waters.

Gravity acts upon any objects in space.
True
Yes, it does. Assuming a constant force, the impulse is equal to the force multiplied by the time the force acts. (If it isn't constant, you will of course use an integral instead.)
The force of gravity is the primary acting force. Air resistance acts in the opposite direction.
