Why value of 'g' decreases when you go inside the earth?
Because the value of "g" varies directly with the sum of the masses of the two bodies acted upon by the force of gravity. If you go inside the earth, only part of the mass of the earth will be attracting you toward its center; the mass of the part of the earth that is farther from the center than you are will be attracting you away from the center. If it were possible to reach the center of the earth, the value of "g" would reach zero because the mass of the earth would be acting upon equally you in all directions.
'what is value of G on the surface of Mars'?
0.376 g
How do scientist calculate the weight of the earth?
First of all let us make a correction. It is not weight of the earth it is only MASS of the earth. By gravitational field concept we arrive at one expression for acceleration due to gravity as g = G M/ R2 G - universal gravitational constant. R-radius of the earth. g-of course measured by the simple pendulum experiment. Knowing g, G, R, we can compute M ie mass of the earth as M = gR2/G Cavendish was the first scientist who found the mass of the earth. But we say so colloquially that he was the first man who weighed the earth.
What is the effect of depth on the earth on the value of g?
As soon as you go below the surface, it will decrease (dont ask for the calculations) until at its centre where acceleration due to gravity will be 0.
The surface of the earth starts with g?
The Earth's surface, where it is not water, is called the ground.
Why value of 'g' decreases due to increase in length?
as we go far from earths surface the value of g decreases this is because g is inversely proportional to the value of r^2(which is the distance of the body from the center of the earth.
When you go deeper inside the earth the value of g increases or decreases?
it decreses
What will happen to the value of g if the compound pendulum is taken nearer to the centre of earth?
The acceleration of gravity (value of 'g') is maximum on the earth's surface, and it decreases from there in both directions ... up into the air or down into the earth.
What is the earth's gravity in terms of acceleration?
9.8 m/s2 ---------------------- Yes this is the average value of acceleration due to gravity near by the surface of the earth. As we go higher and higher level this g value decreases and becomes almost negligible. Same way as we go deeper and deeper the g value decreases and at the centre of the earth its value becomes zero.
If an object is moving away from earth what will be value of g?
For every 1% increase in the object's distance from the center of the earth,the value of 'g' in the vicinity of the object decreases almost 2%.
How would the time period of a simple pendulum clock be affected if it were on the moon instead of the earth?
The time period of a pendulum would increases it the pendulum were on the moon instead of the earth. The period of a simple pendulum is equal to 2*pi*√(L/g), where g is acceleration due to gravity. As gravity decreases, g decreases. Since the value of g would be smaller on the moon, the period of the pendulum would increase. The value of g on Earth is 9.8 m/s2, whereas the value of g on the moon is 1.624 m/s2. This makes the period of a pendulum on the moon about 2.47 times longer than the period would be on Earth.
The weight of an object due to?
The weight is due to the force exerted on the body by the gravitational pull by the earth. If no such gravitational pull on the body, then the body becomes weightless. In free space, very far away from the earth the astronauts experience weightlessness. So if M is the mass of the body, then Mg is the weight of the body. Hence weight depends on the value of 'g'. The value of g is the least at the equatorial region. It will be maximum at the poles. As we go at higher altitudes g value decreases. Same way as we go towards the centre of the earth ie as depth increases, g value decreases.
Why value of 'g' decreases when you go inside the earth?
Because the value of "g" varies directly with the sum of the masses of the two bodies acted upon by the force of gravity. If you go inside the earth, only part of the mass of the earth will be attracting you toward its center; the mass of the part of the earth that is farther from the center than you are will be attracting you away from the center. If it were possible to reach the center of the earth, the value of "g" would reach zero because the mass of the earth would be acting upon equally you in all directions.
What is the value of 'g' if the earth stops rotating?
i think value of g becomes zero
What will happen to value of g if compound pendulum is taken nearer to the centre of the earth?
The acceleration of gravity decreases as the observation point is taken deeper beneath the surface of the Earth, but it's not the location of the compound pendulum that's responsible for the decrease.
What is the value of G at center of earth?
Zero.
What is the value of 'g' at center of earth?
Zero.
