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

.
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.
