Study Plan

1
Day 1–2

Learn the Theory

Read the textbook chapter carefully. Note down definitions, formulas and key ideas. Focus on: 1. Historical background and Kepler’s laws, 2. Universal law of gravitation, 3. Gravitational constant and weighing the Earth.

2
Day 3

Practise

Solve the textbook exercises and extra practice questions. There are 155 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

  • Ptolemy's planetary model was geocentric.
  • Aryabhatta mentioned a heliocentric model.
  • Copernicus proposed a definitive heliocentric model.
  • Law of orbits is Kepler's first law.
  • Law of areas is Kepler's second law.
  • Law of periods is Kepler's third law.
  • Gravitational force varies as product of masses.
  • Gravitational force varies inversely as square of separation.
  • The force is attractive.

Common Mistakes to Avoid

Gravity becomes weaker only because the object is far away, so the same formula can be used with the same radius everywhere.

Weightlessness in orbit means gravity is almost zero there.

Linear momentum is conserved in the motion of a planet or satellite around Earth.

Memory Tips

Newton's universal law of gravitation

Kepler's first law of orbits

Kepler's second law of areas

Kepler's third law
