Topics Covered in Gravitation in ONE SHOT for NEET 2026

This ONE SHOT session is designed to cover the Gravitation syllabus for NEET 2026 in a structured and exam-oriented manner.

1. Newton’s Law of Gravitation & Superposition Principle

This section builds the foundation of the chapter with the universal law of gravitation:

F = Gm₁m₂ / r²

• Explains properties like inverse square law, always attractive nature, and long-range force

• Introduces universal gravitational constant (G = 6.67 × 10⁻¹¹ Nm²/kg²)

• Covers superposition principle for multi-mass systems

• Important for vector-based numericals and equilibrium questions

2. Acceleration Due to Gravity (g) & Its Variations

This section focuses on one of the most frequently asked NEET concepts:

g = GM/R²

• Concept of free fall acceleration near Earth

• Variation of g with:

• Height (h)

• Depth (d)

• Graph-based questions and approximations like g′ ≈ g(1 − 2h/R)

• Key insight: g is maximum at Earth’s surface

3. Escape Velocity & Kepler’s Laws of Planetary Motion

This section explains motion beyond Earth and planetary dynamics:

ve = √(2GM/R)

• Escape velocity concept and dependence on mass and radius

• Independence from angle of projection

• Kepler’s Laws:

• Elliptical orbits

• Equal areas in equal time

• T² ∝ a³ relationship

• Important for conceptual + numerical questions

4. Satellite Motion, Orbital Mechanics & Energy

This section connects gravitation with circular motion and energy:

v = √(GM/r)

• Orbital speed and time period

• Energy relations:

• Kinetic Energy

• Potential Energy

• Total Energy (negative → bound system)

• Types of satellites:

• Geostationary (24 hours, ~35,800 km)

• Polar (~100 min, weather use)

• Concept of weightlessness (free fall condition)

5. Gravitational Field, Potential & Advanced Concepts

This advanced section is crucial for high-level NEET questions:

V = -GM/r

• Gravitational field intensity and potential

• Relation: g = −dV/dr

• Concepts of:

• Hollow and solid spheres

• Binding energy

• Ring system field and potential

• Important distinction between scalar (V) and vector (g) quantities
