Revision Notes — Gravitation
Key concepts, formulas, and definitions from Gravitation for NEET-UG Physics preparation.
Key Topics to Revise
Newton's Universal Law of Gravitation
- Every particle in the universe attracts every other particle with a force directly proportional to the product of their masses and inversely proportional to the square of distance between them
- The force is always attractive and acts along the line joining the centers of the two masses
- Universal gravitational constant G = 6.67 × 10⁻¹¹ N⋅m²⋅kg⁻²
Acceleration due to Gravity
- Acceleration produced in any body due to Earth's gravitational pull is called acceleration due to gravity (g)
- Standard value g = 9.8 m/s² at sea level
- Value of g is independent of mass, shape, or density of the falling object
Variation in Acceleration due to Gravity
- g varies with height above Earth's surface - decreases with increasing height
- g varies with depth below Earth's surface - decreases linearly with depth
- g varies due to Earth's elliptical shape - maximum at poles, minimum at equator
Gravitational Field and Potential
- Gravitational field intensity at a point is gravitational force per unit mass at that point
- Gravitational potential is work done per unit mass in bringing mass from infinity to that point
- Field intensity is vector quantity, potential is scalar quantity
