Latitude at a place is the angular distance of that location from the Earth’s equator, measured in degrees north or south. Class 11 Physics Gravitation CBSE Exam 2024-25
The Earth’s oblate shape causes gravitational acceleration to be slightly stronger at the poles than at the equator, increasing a body’s weight when moved poleward. Class 11 Physics Gravitation CBSE EXAM 2024-25
For the same change in gravitational acceleration (g), height (h) and depth (d) are related by h = 2d. Class 11 Physics Gravitation CBSE EXAM 2024-25
At the Earth’s center, the weight of a body is zero because gravitational forces from all directions cancel out. Class 11 Physics Gravitation CBSE EXAM 2024-25
