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
