On Earth, the effective value of g, or acceleration due to gravity, is not influenced by temperature. Many factors go into determining the value of gravity, while temperature has no bearing in this sense.

Gravity is another influence due to the Earth’s rotation, which provides a centrifugal force that decreases the effective weight at the equator. This means that the Earth’s gravity is weaker at the equator than it is at the poles because the Earth rotates. Besides, Earth is not a perfect sphere; it is more like an oblate spheroid. The reason gravity is weak at high altitudes is because the distance from the Earth’s center is higher. On the other hand, temperature does not affect the value of gravitational force at the surface of the Earth. Although it can alter physical properties, including air density, it does not alter the mass of the Earth or the distance to its center. Hence, in terms of factors that will affect acceleration due to gravity, temperature can be ignored, meaning it is considered a constant when using the variation of gravity as a function at different points on Earth.
