... fall at the surface of the earth . If the earth were a sphere , and at rest , a body would be equally attracted , that is , it would have the same weight at every point of its surface , because the surface of a sphere is everywhere ...

... fall through in the first second of her descent to the earth , were she not prevented by the centrifugal force ( N. 18 ) arising from the velocity with which she moves in her orbit . The moon is thus retained in her orbit by a force ...

... fall to the sun by its gravity . Were the sun not to attract it , the planet would fly off in the tangent . Thus , when the planet is at the point of its orbit farthest from the sun , his action overcomes the planet's velocity , and ...
