WebGravitational Acceleration The acceleration due to the Earth's gravity at any height h above the surface of the Earth is given by the equation g = −G(R+h)2M where G is the gravitational constant (6.672× 10−11 N m2/kg2),M is the mass of the earth (5.98 ×1024 kg),R is the mean radius of the Earth (6371 km), and h is the height above the ... WebJan 30, 2024 · Acceleration due to Gravity: Value of g, Escape Velocity. A free-falling object is an object that is falling solely under the influence of gravity. Such an object has an acceleration of 9.8 m/s/s, downward (on Earth). This numerical value is so important that it is given a special name. It is known as acceleration due to gravity. flower dab a dot
