Why the acceleration due to gravity decreases on going inside the earth?
Acceleration due to gravity decreases because the surrounding mass that attracts the object decreases.
When we go inside the earth the acceleration due to gravity?
Acceleration due to gravity is represented by g. The standard value of g on the surface of the earth at sea level is 9.8 m/s2….
| Acceleration Due to Gravity (g) | |
|---|---|
| Symbol | g |
| SI Unit | ms-2 |
| Formula | g = GM/r2 |
| Values of g in SI | 9.806 ms-2 |
How does acceleration due to gravity change when we go from equator to the pole?
So, as we go from the equator to poles, the value of g increases. Since the distance at the poles is smaller than that of the equator hence we can say that person has more acceleration due to gravity on the poles than the equator. The value of acceleration due to gravity increases as we move from equator to pole.
Does gravity decrease towards the center of the earth?
As you move towards the center, there is less and less of the Earth closer to the center than you are, so the gravitational field gets weaker and your weight decreases. At the exact center of the Earth, the gravitational field is actually zero.
Why acceleration due to gravity of Earth is less at equator than at poles?
Answer: Because the force due to gravitational attraction between two bodies (the Earth and the object being weighed) varies inversely with the square of the distance between them, an object at the Equator experiences a weaker gravitational pull than an object at the poles.
Why is the acceleration due to gravity minimum at the equator?
As the radius decreases, the acceleration due to gravity increases. As the radius increases, the acceleration due to gravity decreases. So, the acceleration due to gravity is minimum at the equator and maximum at poles.
Does gravity decreases as we go up?
When you go up (away from the surface of the earth) the total distance to all mass is increased; in fact you can consider all mass to be at the center of the earth, and the gravitational force will decrease with the inverse square of the distance to the center.
What happens to gravity at the center of the Earth?
At the very center, the gravitational force is zero because there’s equal mass pulling on you from all sides, and it all cancels. If you built a room there, you could float around freely. That’s what it means to say that gravity is zero at the center of Earth. However, the gravitational well is a different story.
