Why Gravitational Acceleration g is 9.8 m/s²

WebApr 9, 2024 · Earth's gravity, in the universal sense, is entirely characterized by the mass of the planet, roughly 5.97 *10^(24) kg, To calculate acceleration, multiply that by the universal gravity constant G and divide by the square of the distance from the center of the planet. Only if you pick Earth's radius does that give the 9.8 m/s^2 value. The gravity of Earth, denoted by g, is the net acceleration that is imparted to objects due to the combined effect of gravitation (from mass distribution within Earth) and the centrifugal force (from the Earth's rotation). It is a vector quantity, whose direction coincides with a plumb bob and strength or magnitude is given by the norm . In SI units this acceleration is expressed in metres per second squared (in symbols, m/s or m·s ) o… WebNov 29, 2024 · It should be noted that the strength of gravity is not a constant – as you get farther from the centre of the Earth, gravity gets weaker. It is not even a constant at the surface, as it varies from ~9.83 at the poles to ~9.78 at the equator. This is why we use the average value of 9.8, or sometimes 9.81. flash cards animaux anglais cycle 2
