Key Topics to Revise

1

1. Core ideas of gravitation

  • Gravitation is a universal force acting between any two objects in the universe.
  • Newton saw that an apple falls vertically downward and concluded that the earth attracts the apple towards its centre.
  • The force of gravitation acts between the earth and the moon, between planets and the Sun, and between every pair of masses.

2. Kepler’s laws and Newton’s connection

  • Johannes Kepler used Brahe’s observational data to discover three laws of planetary motion.
  • Kepler’s first law says that the orbit of a planet is an ellipse with the Sun at one of the foci.
  • Kepler’s second law says that the line joining the planet and the Sun sweeps equal areas in equal intervals of time.

3. Newton’s universal law of gravitation and the inverse square law

  • Every object in the universe attracts every other object with a definite force.
  • The force is directly proportional to the product of the masses and inversely proportional to the square of the distance between them.
  • If one mass is doubled, the force doubles.

4. Gravity near the earth: g and its variation

  • Acceleration due to gravity is the acceleration produced by the earth’s gravitational force on objects near it.
  • It is a vector quantity and is directed towards the centre of the earth.
  • The acceleration due to gravity is the same for all objects at a given place, regardless of their properties.
