### The gravitational field strength of Venus'?

Gravitational field strength varies from position to position on
a planet.
However, for the surface of Venus, the strength is about 8.87
m/s/s (meters per second per second). That value is for the
acceleration caused by the gravity.
This is slightly less than that experienced on the surface of
the Earth.
In fact it's about 90% of the Earth's.

###### Asked in Gravity

### Where the gravitational field strength is maximum?

value of acceleration due to gravity is maximum at the surface
of earth. So the gravitational field strength.
as g'=g(1-d/R)
at surface d=R
so d=R
so g'=g
at earth's centre g=0. Its value decrease with decrease or
increase in height.
as:
g'=g(1-2h/R) ......for height h
and
g'=g(1-d/R) .....for depth d

###### Asked in Physics, Earth Sciences, The Moon

### What is the effect of friction on the value of gravitational acceleration?

Gravitational acceleration is a constant value for a celestial
body, and doesn't depend on air resistance/friction. The value on
Earth is constant anywhere on Earth, just like the value on Mars is
constant anywhere on Mars. In practical,however, this is different.
Air resistance lowers the value of gravitational acceleration.

###### Asked in Physics

### What instrument measures the pull of gravity on an object?

the answer is spring scale
On Earth, you would use a scale to measure the weight.
A spring scale will give "the pull of gravity" irrespective of
the gravitational field & could be used on the earth or
moon.
A balance gives the mass, related, but it gives a constant value
independent of the gravitational field, and would only be accurate
for "the pull of gravity" with constant gravity.

###### Asked in Chemistry, Elements and Compounds

### Is mass the same as weight Why?

No, mass is the measure of matter. Weight is the strength of a
gravitational pull of an object . Answer: Weight = Mass x (g
local / g standard) It gets confusing on Earth where the
gravitational force (g) is the standard force making the numeric
mass value the same as the numeric weight value as (g local / g
standard)=1

###### Asked in Physics

### When climber reaches the top of the mountain his weight is?

Well weight is force exerted by gravitational field on an
object. So if 'g' is acceleration due to gravity and m is mass of
object then weight(W) of object is W=mg But gravitational
acceleration on earth is given as: g=GM/(R+h)^2 G:Gravitaional
Constant value 6.67*10^-11 Nm^2/kg^2 M:Mass of earth
value:6*10^24kg R:Radius of earth value:6.4*10^6km h:Height of
object above the surface of earth At surface of earth h=0 but at
peak of mountain h will have some finite value. So as h will
increase, g will decrease. Due to decrease in gravitational
acceleration at peak of mountain the "WEIGHT OF CLIMBER WILL
DECREASE"

###### Asked in The Moon, Numbers , Mathematical Constants

### Value of gravitational constant on earth and moon?

It's the same as that of Earth but the value of g varies from
one object to the other. The value of the gravitational constant or
the BIG "G" remains constant. I think you confused it with the
LITTLE "g" which is the gravitation of a object (one with mass) or
the acceleration due to gravity. The value of g on Earth and Moon
is 9.8m/s^2 and 1.6249m/s^2, respectively. I hope this answers you
all.

###### Asked in Planet Jupiter, Gravity

### What is Jupiter gravity surface?

Comparing the size of Jupiter to earth, it is 318 times bigger
than earth, and if the gravitational force of earth is 9.8, than
than it should be 318 times more, but its not that huge, because
gravitational force rely of certain factors that can change its
value. The gravitational force of Jupiter is 254% compared to the
earth. 2.54*9.8= 24.892.

###### Asked in Chemistry, Neutron Stars

### If you weighed 70 pounds on earth how many pounds would you weigh on a neutron star?

The gravitational field of the neutron star is about 2 x 10^11
times stronger than the gravitational field of earth. However, you
have provided a mass in the question and this would remain the same
if you were on a neutron star (mass is a scalar quantity - a common
mistake). Weight is a vector quantity obtained by mulitplying mass
in kg (70 pounds would be about 32kg) by the gravitational field
experienced - so a value of 32 x 9.8 = 313.6 N is your weight on
earth. Your weight on a neutron star is 2 x 10^11 times bigger than
this, so 627.2 x 10^11 N is your weight. Your mass is still
32kg!
