How much is gravity?

Answer
Earth's gravity is 9.8 m/s² or 9.8 N/kg at sea level. This means each kilogram of mass experiences 9.8 Newtons of gravitational force. The strength varies slightly by location—it's about 0.5% stronger at the poles than the euator, and decreases with altitude (about 0.03% less per kilometer above sea level). Other celestial bodies have different gravitational strengths: the Moon has 1.63 m/s², Mars has 3.71 m/s², and Jupiter has 24.79 m/s². In terms of gravitational constant, G = 6.674 × 10⁻¹¹ N⋅m²/kg², which is used for calculating gravitational forces between any two masses.
