Key Topics to Revise

1

Kepler's Laws of Planetary Motion

  • Kepler's laws were derived from observations of planetary motion by Tycho Brahe
  • These laws laid the foundation for Newton's Universal Law of Gravitation
  • All three laws apply to any object orbiting another under gravitational force
2

Newton's Universal Law of Gravitation

  • Every particle in the universe attracts every other particle with a gravitational force
  • The force is directly proportional to the product of masses
  • The force is inversely proportional to the square of distance between them
3

Acceleration Due to Gravity

  • Acceleration due to gravity varies with height above Earth's surface
  • It also varies with depth below Earth's surface
  • Maximum value of g occurs at Earth's surface
4

Gravitational Potential Energy

  • Gravitational force is conservative, so potential energy can be defined
  • Potential energy is taken as zero at infinite distance
  • Gravitational potential energy is always negative for bound systems
