Where does Earth have the strongest gravity and how will your mass and weight be affected when you travel from poles to the equator of the earth?
The strongest gravity on Earth is found at the poles, while the weakest gravity is at the equator. This is due to the Earth's shape and the distribution of its mass. The Earth is not a uniform sphere, and its mass is concentrated at the center. As a result, the gravitational force at the poles is slightly stronger than at the equator
Earth's Gravity is strongest on the ground, usually at sea level, and weaker as you move away from the core, eg the peak of Mt. Everest. The gravity at the poles is stronger than the equator, partly because the obloid earth is slightly wider, but only by a small ratio. The earth is an oblate spheroid, and that means it bulges out in the middle (the equator). That also means the poles end up a little closer to the centre of gravity. That is why on the surface of earth, at the poles the intensity of gravity is the maximum.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. Now the weight of the body is directly proportional to the acceleration due to the gravity 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. The centrifugal force at the poles is zero. Your total weight at sea level at the equator is therefore 9.764 m/s2 times your mass, whereas your weight is 9.863 m/s2 times your mass at the poles. So, from the above explanation we can say that the person will feel maximum weight at the poles as it is near to the center of the earth and at the equator the person will feel minimum weight because it is far from the center of the earth when compared to the poles. As we move away from the equator towards the poles, the intensity of sunlight received decreases. This is because the angle of incidence of the sun's rays becomes more inclined as it approaches the poles. An equator is an imaginary line around the middle of a planet or other celestial body. It is halfway between the North Pole and the South Pole, at 0 degrees latitude. An equator divides the planet into a northern hemisphere and a southern hemisphere. Earth is widest at its Equator.
