If we draw in the acceleration and velocity vectors of an orbiting body, you'll see why it acceleration due to gravity does not cause an orbiting body to fall towards an object. First, assume the orbit is circular. In any motion of an object, the velocity vector is tangent to the object's path. Because acceleration due to gravity is straight towards the ...

You're right - the objects are always accelerating while orbiting, and this acceleration is due to gravitational influence. However, force/acceleration don't always cause an increase in speed. For example, a force acting opposite to the velocity will slow an object, and a force acting perpendicular to the velocity will merely change its direction. In an ...

It does keep accelerating. It's velocity in the direction of the object being orbited keeps increasing. But this direction keeps changing. The reason the satellite's total speed doesn't increase, at least in the case of a circular orbit, is that while the it's velocity towards the object increases, it's tangential motion moves it forward so that that ...
