The value of g is independent of the mass of the object and only dependent upon location – the planet the object is on and the distance from the center of that planet.
How does g vary with mass?
The value of gravitational acceleration changes according to the altitude of a place . In this way the weight also changes according to the altitude of a place. But,mass is constant untill we physically reduce the mass of an object. And the mass is not dependent on the amount of gravitational acceleration.
How is G different from G?
| Acceleration due to gravity ( g ) Universal Gravitation Constant ( G ) | It will change from place to place. Constant at any place in the universe. | Value of g=9.8 m/s 2 Value of G=6.673×10-11 Nm 2 /kg 2 |

What is value of G and G at the Centre of Earth?
| Location Distance from Earth’s center (m) Value of g (m/s 2 ) | Earth’s surface 6.38 x 10 6 m 9.8 | 1000 km above surface 7.38 x 10 6 m 7.33 |

Why is g independent of mass?
Mass is intrinsic to matter, but weight is the force of gravity on that mass. ... The acceleration due to gravity does not depend on the mass of the object falling, but the force it feels , and thus the object’s weight, does.
Do heavier objects fall faster?
Acceleration of Falling Objects
Heavier things have a greater gravitational force AND heavier things have a lower acceleration. It turns out that these two effects exactly cancel to make falling objects have the same acceleration regardless of mass.
Where is the value of g is maximum?
The value of G is maximum at the poles . This is due to the closeness between the poles and the center of the earth.
How would the value of g and g be affected if the mass of Earth becomes four times?
Gravity is in g is equal to earth masses/earth radius^2. By increasing mass, we proportionally increase volume (assuming constant density). This means that 4 Earth would have a radius that is cube root 4 bigger than Earth. So due to the mass, the gravity increases by a factor of 4 .
What is relation between g and g Class 9?
Relationship Between G and g
g is the acceleration due to the gravity measured in m/s 2 . G is the universal gravitational constant measured in Nm 2 /kg 2 . R is the radius of the massive body measured in km. M is the mass of the massive body measured in Kg.
What is the difference between Big g and small g?
Colloquially, the gravitational constant is also called “Big G”, distinct from “small g” (g), which is the local gravitational field of Earth (equivalent to the free-fall acceleration). Where M ⊕ is the mass of the Earth and r ⊕ is the radius of the Earth, the two quantities are related by: g = GM ⊕ r ⊕ 2 .
What are the difference between g and g are both of them universal constant?
| Gravitational constant (G) Acceleration due to gravity (g) | Universal constant and its value is 6.673×10 – 11 Nm 2 kg – 2 . Constant at a given place and its value changes from place to place. Mean value of g on surface of earth is 9.8 ms – 2 . |

How do I calculate g?
The acceleration g=F/m 1 due to gravity on the Earth can be calculated by substituting the mass and radii of the Earth into the above equation and hence g= 9.81 m s – 2 .
At what height value of g is zero?
Near the surface of the Earth (sea level), gravity decreases with height such that linear extrapolation would give zero gravity at a height of one half of the Earth’s radius – (9.8 m. s − 2 per 3,200 km.)
What is value of g’on moon?
The acceleration due to gravity on the surface of the Moon is approximately 1.625 m/s 2 , about 16.6% that on Earth’s surface or 0.166 ɡ. Over the entire surface, the variation in gravitational acceleration is about 0.0253 m/s 2 (1.6% of the acceleration due to gravity).
What falls faster a feather or a rock?
Galileo discovered that objects that are more dense, or have more mass , fall at a faster rate than less dense objects, due to this air resistance. A feather and brick dropped together. Air resistance causes the feather to fall more slowly.
Does mass affect speed?
The mass of an object does not change with speed ; it changes only if we cut off or add a piece to the object. ... Since mass doesn’t change, when the kinetic energy of an object changes, its speed must be changing. Special Relativity (one of Einstein’s 1905 theories) deals with faster-moving objects.
