Suppose a particle of mass M is under gravitational attraction. The Newton's law of gravitation says that F=GMm/r^2, and the part Gm/r^2 is g (acceleration due to gravity how?)
At the surface of the earth, Gm/r^2= g using m= mass of the earth, r= radius of the earth.manimaran1605 said:Suppose a particle of mass M is under gravitational attraction. The Newton's law of gravitation says that F=GMm/r^2, and the part Gm/r^2 is g (acceleration due to gravity how?)

The gravitational acceleration g is a constant value that represents the acceleration due to Earth's gravity. It is approximately 9.8 meters per second squared (m/s²).
Gravitational acceleration g is calculated by dividing the force of Earth's gravity on an object by the object's mass. It can also be calculated by multiplying the universal gravitational constant (G) by the mass of Earth and dividing by the radius of Earth squared.
Yes, the gravitational acceleration g varies on different planets depending on their mass and radius. For example, the gravitational acceleration on Mars is approximately 3.7 m/s², while on Jupiter it is approximately 24.8 m/s².
The higher the altitude, the further an object is from Earth's center of mass, resulting in a decrease in gravitational acceleration g. This is because the force of gravity decreases with distance.
Gravitational acceleration g cannot be altered by humans. It is a natural constant determined by the mass and size of a planet. However, objects can experience a different acceleration due to other forces such as air resistance or the force of a rocket engine.
