Overview of JEE Physics Gravitation

This chapter focuses on:

• Understanding the universal law of gravitation

• Studying motion of planets and Kepler’s laws

• Analyzing gravitational field, potential, and energy

• Solving satellite motion problems

• Applying gravitation concepts to JEE-level numericals

Gravitation connects mechanics with astronomy and deepens understanding of natural forces.

Importance of Gravitation for JEE

Gravitation is important because:

• It has direct weightage in JEE Main & Advanced

• Many problems test conceptual clarity and derivations

• It strengthens understanding of central forces

• It is essential for satellite motion and orbital mechanics

• It builds foundation for higher-level physics topics

Universal Law of Gravitation

The universal law of gravitation states that:

• Every two masses attract each other

• Force is directly proportional to the product of masses

• Force is inversely proportional to the square of distance between them

This law explains phenomena from falling objects to planetary motion.

Gravitational Constant and Field

• Gravitational constant is universal

• Gravitational field represents force per unit mass

• Direction is always towards the attracting mass

These concepts are essential for solving field-based numerical problems.

Gravitational Potential and Potential Energy

• Gravitational potential is work done per unit mass

• Potential energy is energy due to position in gravitational field

• Important for energy-based problem-solving

These topics simplify calculations in orbital motion problems.

Motion of Planets and Kepler’s Laws

Kepler’s laws describe planetary motion:

1. Law of orbits

2. Law of areas

3. Law of periods

These laws form the basis of astronomical mechanics and are frequently tested conceptually.

Satellites and Orbital Motion

Satellite motion involves:

• Orbital velocity

• Time period of revolution

• Geostationary satellites

• Energy of satellites

Satellite-based questions are common in JEE Main.

Acceleration Due to Gravity

Acceleration due to gravity:

• Varies with altitude, depth, and latitude

• Determines weight of objects

• Plays a key role in free fall problems

Understanding its variation helps in solving advanced numericals.

Numerical Problems in Gravitation

Common numerical problems include:

• Force between masses

• Satellite motion calculations

• Escape velocity

• Energy of orbits

• Variation of gravity

Regular practice improves speed and confidence.

Stepwise Problem-Solving Approach

1. Identify given quantities

2. Choose correct gravitation formula

3. Apply energy or force equations

4. Solve step by step
