What is the difference between free fall acceleration and gravitational acceleration?
How do they relate to weightlessness in space?
In space, objects appear to be weightless because they are in a state of free fall. The object is still affected by the gravitational acceleration of the planet or object it is orbiting, but it is moving so fast that it continuously falls and misses the surface. This creates a sensation of weightlessness.
