Acceleration due to gravity – how it changes with height and depth

Gravitational Attraction of the earth and Acceleration due to gravity In this post at first we will work on the expression of Acceleration due to gravity or gravitational acceleration (g) on the earth’s surface. We will take help of Newton’s Law of Gravitation as well as Newton’s second Law of Motion. Then we will explore how height or
