If the Earth was spinning faster, depending on how much faster, the centrifugal force, perpendicular to the axis of the Earth would grow larger. This centrifugal force, most evident around the equator and responsible for the Earth bulging at the equator and not being completely spherical, acts parallel but in the opposite direction of gravity.

Currently at the rate the Earth rotates, the gravitational force at the equators is much stronger than that of the centrifugal force, resulting in a net positive force towards the centre of the planet at the equator. However, if the Earth’s rotational speed increased dramatically such that the gravitational and centrifugal forces cancelled out, the surface of the equator would essentially experience no net force, meaning gravity would appear to be 0… if you jumped straight up from the surface, you would never return to the ground. If the Earth was spinning fast enough that the centrifugal force became greater than the pull of gravity at the equator, things on the surface would start flying off into space, being flung off in tangents to their position on the equatorial circumference of the planet.

Remains constant as mass is point object
