What happens to the weight of body as we go higher above the surface of Earth?
The mass of a body or object is constant and does not change from place to place. But acceleration due to gravity is inversely proportional to the square of the distance from the centre of earth. Thus, as we go higher above the surface of the earth the weight of the body decreases.
What is the effect on weight of body if we goes down below the surface of Earth?
All pulling of gravity in every direction cancels itself out, and you experience zero gs. Thus, your weight decreases as you go below the surface of the earth.
Where will a body weight more one Kilometre above the surface of Earth or one Kilometre below the surface of Earth?
Therefore weight of the body will be more at depth of 1 km.
What happens to the weight of a person when he is deep inside the earth?
As you go deep to the Earth’s surface, in a mine shaft for example, the force of gravity lessens. Weight and gravitational pull continue to decrease as you get deepr to the Earth.
How would your weight on the surface of the earth compare to your weight at a point in space a distance r Earth’s radius above Earth’s surface?
If you are above the surface of the Earth, then r is greater than the Earth’s radius, so the gravitational force (and your weight) would be less. Your weight would be less because the gravitational field inside the Earth is less than the gravitational field at the surface.
Does your weight change as you move above or below Earth’s surface?
Travelling away from Earth As you travel away from the Earth’s surface, your mass stays the same but your weight reduces as gravitational pull decreases. For example, an astronaut orbiting the Earth and floating weightlessly in the cabin still has the same mass.
Where will the body weight more?
The weight of a body depends on the force with which it is attracted towards the centre of the Earth. But this force is greater at the pole on account of less distance from the centre of the Earth. Due to this, the body weighs more at the poles than at the equator.
Where will a body weigh more at Delhi or at Shimla Why?
At Delhi, a body weighs more as compared to shimla because at higher altitudes the value of g (acceleration due to gravity) decreases.
Why a person has less weight on top of a mountain?
Answer: This is because the peak of a mountain is higher and farther away from the center of the earth, so the pull of gravity in that spot is weaker than at the bottom of the mountain. Remember, even if you weigh less because of a change in gravity’s force on your body, your body’s mass is still the same.
