Is Gravity Caused by Spin or Mass? Explaining the True Source of Gravity

Discover whether gravity is caused by spin or mass, based on Einstein's General Relativity and Earth's example.

33 views

Gravity is not due to spin. Gravity is the force of attraction between masses, described by Einstein's General Theory of Relativity as the curvature of spacetime caused by mass. Earth's gravity, for example, stems from its mass and energy, not its rotation. However, Earth's spin does cause centrifugal force, which slightly affects the apparent weight of objects.

FAQs & Answers

  1. What is the true cause of gravity? Gravity is caused by the curvature of spacetime due to mass and energy, as described by Einstein's General Theory of Relativity.
  2. Does the Earth's spin create gravity? No, Earth's spin does not create gravity. Gravity results from Earth's mass, while the spin produces centrifugal force that slightly affects apparent weight.
  3. How does centrifugal force affect gravity? Centrifugal force from Earth's rotation reduces the apparent weight of objects slightly but does not generate gravity itself.
