Study Plan

1
Day 1–2

Learn the Theory

Read the textbook chapter carefully. Note down definitions, formulas and key ideas. Focus on: Newton's Law of Gravitation, Gravitational Field and Potential Energy, Acceleration Due to Gravity (g).

2
Day 3

Practise

Solve the textbook exercises and extra practice questions. There are 54 questions available for this chapter.

3
Day 4

Revise & Test

Revise key points without looking at your notes. Take a practice quiz and mark weak areas for another pass.

Day 7

Spaced Revision

Come back to Gravitation after a week. Use flashcards for quick recall and try past exam questions on this chapter.

What to Focus On

  • Gravitational force is always attractive.
  • It acts along the line joining the centers of two masses.
  • The force is proportional to the product of the masses and inversely proportional to the square of the distance.
  • G was first measured by Henry Cavendish.
  • Value of G is $6.67 \times 10^{-11} \, \mathrm{Nm^2/kg^2}$.
  • Cavendish’s experiment used a torsion balance to measure extremely weak gravitational forces.
  • Gravitational field strength is force per unit mass.
  • It is a vector quantity directed towards the source mass.
  • Its magnitude decreases with the square of the distance from the source.

Common Mistakes to Avoid

Heavier objects fall faster than lighter ones because gravity pulls them more.

g is constant everywhere on Earth — same at poles, equator, and at height.

Mass and weight are the same thing and can be used interchangeably.

Memory Tips

Newton's Universal Law of Gravitation: F = G(m₁m₂)/r²

G is the Universal Gravitational Constant (6.67 × 10⁻¹¹ Nm²/kg²)

Gravitational force is always attractive
