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
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.
Friction with the atmosphere counter acts the pull of gravity.
Certainly it appears that gravity does so.
force is mass x acceleration which for orbit is mass (m) x velocity squared (v^2)divided by radius (R) above center of earth. Since there is also acceleration of gravity (g) then g = v^2/R. You can now calculate velocity of satellite to stay in orbit - it is about 17.500 mph

Nothing accelerates unless/until force acts on it.This is exactly Newton's first law of motion.
When an unbalanced force acts on an object, the weight of the object decreases.
