The intensity of the gravitational field is the force per unit mass at a point. It is a vector quantity. Class 11 Physics Gravitation Session 2024-25
The gravitational field is the region around a mass where another mass experiences a gravitational force of attraction. Class 11 Physics Gravitation CBSE Exam 2024-25
Factors include Earth’s shape, density variations, and local geological structures. Accurate g measurements aid geophysics, navigation, and mineral exploration. Class 11 Physics Gravitation CBSE Exam 2024-25
Acceleration due to gravity g increases linearly with distance r inside the Earth, peaks at the surface, then decreases inversely with r². Class 11 Physics Gravitation CBSE Exam 2024-25
The Earth’s rotation reduces gravity at a latitude due to centrifugal force, which is maximum at the equator and decreases poleward. Class 11 Physics Gravitation CBSE EXAM 2024-25
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
