Q: If the world were to stop spinning, would the people and everything on it be considered ‘lighter’ or ‘heavier’? Would any change take place? And does centrifugal force have an effect on gravity?

Physicist: Centrifugal force* due to the spinning of the Earth is certainly a measurable effect, but it’s a small effect. At the north and south poles objects weigh exactly what they should, and at the equator things weigh slightly less. Centrifugal force always points out from the Earth’s axis, whereas gravity always points toward the Earth’s center. The economy would take a real hit if the Earth suddenly came to a stop. *Any time that centrifugal forces are mentioned in the vast crucible that is the internet, a small but vocal cadre makes it known that the centrifugal force isn’t really a force.
