Gravitational acceleration on Earth: 9.8195 m/s^2

  • Gravity here is 100.1% of Earth's surface gravity. You would feel significantly heavier.
  • A falling object gains this much speed every second, ignoring air resistance.

Next stepTry entering an altitude to see how gravity weakens with height, such as 408,000 m for the ISS orbit.
