Understanding Gravitation in Class 11 Physics
Gravitation is a fundamental force that governs the motion of celestial bodies and everyday objects. In the Class 11 Physics curriculum, the Gravitation chapter provides essential concepts that are critical for NEET preparation.
Key Concepts of Gravitation
- Universal Law of Gravitation:
- Every point mass attracts every other point mass with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
- Gravitational Force:
- The force of attraction between two masses is given by the formula:
- F = G * (m1 * m2) / r², where G is the gravitational constant.
- Acceleration due to Gravity (g):
- The acceleration experienced by an object due to the Earth's gravitational pull is approximately 9.81 m/s².
- Gravitational Potential Energy:
- The work done in bringing a mass from infinity to a point in a gravitational field is known as gravitational potential energy (U = -G * (m1 * m2) / r).
