Newton's Law of Universal Gravitation states:
Every particle with mass in the universe attracts every other particle with a
force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centres.

# data[].attributes.body
WHERE:
F = force
m = mass
r = distance two objects are apart (distance between their centers)
G = Universal gravitational constant (Newton's constant) = 6.673×10⁻¹¹ N m² kg-2

Superman's strength must be partly attributed to the gravitational field of his home planet, Krypton.

The people of Krypton evolved to stand, walk, and lift ordinary objects in Krypton's strong gravitational field.

When Superman came to Earth, he found that his Kryptonian physique was sort of over-designed.

He could "leap over tall buildings in a single bound", for example. Let's see Superman in action:

At the point where the gravitational force on Apollo towards Earth is equal to the gravitational force on Apollo towards the Moon, the forces are equal but act in opposite directions and BALANCE. The resultant or net force on Apollo will then be the vector sum of the opposing forces which is zero.

In the vacuum of space on a spacewalk (with no air molecules or supportive surfaces), the astronaut is acted upon by the force of gravity only and are in free fall towards Earth (at the acceleration of gravity, together with the spacecraft) but continue to miss the earth. Since the astronaut is therefore in ORBIT he appears weightless.
