Topics in Gravitation

1

Universal Law of Gravitation

  • Every object in the universe attracts every other object with a gravitational force
  • Gravitational force is always attractive, never repulsive
  • The force acts along the line joining the centers of two objects
2

Free Fall and Acceleration Due to Gravity

  • Free fall occurs when objects fall under gravity alone, without air resistance
  • All objects in free fall experience the same acceleration regardless of their mass
  • Acceleration due to gravity (g) is approximately 9.8 m/s² near Earth's surface
3

Mass and Weight

  • Mass is the measure of inertia and remains constant everywhere in the universe
  • Weight is the force with which Earth attracts an object
  • Weight varies from place to place but mass remains constant
4

Thrust and Pressure

  • Thrust is the force acting perpendicular to a surface
  • Pressure is thrust per unit area (Pressure = Thrust/Area)
  • Same force applied on smaller area creates greater pressure
