At what condition does a body become weightless at the equator?

A body become weightless at the equator if force of gravity and centrifugal force of the earth become equal.

When the centrifugal force is equal to the gravitational force of the body in that condition the body experiences weightlessness at the equator. The weight of the body is due to the higher gravitational force of the earth than its centrifugal force so if both forces are equal to each other than the weight becomes zero.

If the earth start to spin faster about 17 times, then the centrifugal force would become equal to the gravitational force and an object would experience weightlessness so we can conclude that a body become weightless at the equator if force of gravity and centrifugal force of the earth become equal.

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
