Why acceleration due to gravity is maximum at poles and minimum at 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.

Why is acceleration due to gravity maximum at the polar region?

It is frequently stated that the value of the acceleration due to gravity at the pole is larger than at the equator because the poles are closer to the center of the earth due to the earth’s oblateness. The measured value is larger because the earth’s density is not uniform but increases toward the center.

Where the value of acceleration due to gravity will be minimum on earth?

the equator
The value of ‘g’ is minimum at the equator because earth is not a perfect sphere. Its radius is maximum at the equator. Hence, according to the equation g = GM/R2, the equator is the place where g will be minimum.

Why is weight minimum at the equator?

The equator is moving quickly as the earth’s spins, so it has a lot of centrifugal force. In contrast, the poles are not spinning at all, so they have zero centrifugal force. Since there is more centrifugal force at the equator to cancel gravity, your overall weight at the equator versus at the poles is even less.

Why is weight maximum at pole or equator?

So the acceleration due to gravity is minimum at the equator and maximum at the poles on the surface of the earth. So the weight of the body is maximum at the poles and minimum at the equator on the surface of the earth. So this is the required answer.

Why gravity is minimum at equator?

Gravity is often assumed to be the same everywhere on Earth, but it varies because the planet is not perfectly spherical or uniformly dense. In addition, gravity is weaker at the equator due to centrifugal forces produced by the planet’s rotation.

Why the value of g is maximum at pole and minimum at equator Class 9?

The value of acceleration due to gravity is maximum at poles and minimum at equator. This is because earth is flattened at poles and it is bluged out at equator.

Why is gravitational force minimum at the equator?

The distance of the equator from the center of the earth is greater than that of the poles. As a result, gravitational acceleration is lower at the equator as compared to the poles. Therefore, it is clear that the gravitational force is minimum at the equator and maximum at the poles.

Where is maximum gravity on Earth?

Mount Nevado Huascarán in Peru has the lowest gravitational acceleration, at 9.7639 m/s2, while the highest is at the surface of the Arctic Ocean, at 9.8337 m/s2.

Where on the surface of the earth is the radius minimum?

Regardless of the model, any radius falls between the polar minimum of about 6,357 km and the equatorial maximum of about 6,378 km (3,950 to 3,963 mi).

What is the acceleration due to gravity at the equator?

In combination, the equatorial bulge and the effects of the surface centrifugal force due to rotation mean that sea-level gravity increases from about 9.780 m/s2 at the Equator to about 9.832 m/s2 at the poles, so an object will weigh approximately 0.5\% more at the poles than at the Equator.

Why is the Equitorial radius greater than the polar radius?

Distance from center of earth : Equitorial radius is greater than the polar radius by 21 km because of spinning earth, gravitational effects of sun and moon, solar system being planar, etc. Since force is inversely proportional to the square of distance between objects, force decreases substantially.

What is the radius of the Earth’s axis?

The earth has a radius of 6380 km and turns around once on its axis in 24 h. 1)What is the radial acceleration of an object at the earth’s equator?

How far is the equator from the center of the Earth?

If you stand at sea level on the equator, you are 6378 km from the center of the earth. In contrast, at each pole, you are only 6357 km from the center of the earth. Since the strength of gravity weakens as you get farther away from a gravitational body, the points on the equator are farther and have weaker gravity than the poles.

Why does Earth have minimum gravity at equator and maximum at pole?

Mass: As Earth has more mass at equator (larger radius of equator compared to pole) , this particular factor increases the gravity at equator. Hence, the first two factor has larger contribution to the overall gravity. Thus, we have minimum gravity at equator and maximum at the pole.
