Topics in Gravitation
Universal Law of Gravitation
- Newton discovered that the same force causes apples to fall and moon to orbit Earth
- Every object in the universe attracts every other object with gravitational force
- Gravitational force is directly proportional to product of masses
Free Fall and Acceleration due to Gravity
- Free fall occurs when objects fall under gravity alone (no air resistance)
- All objects fall at same rate in vacuum regardless of mass
- Acceleration due to gravity (g) = 9.8 m/s² near Earth's surface
Mass and Weight
- Mass is measure of inertia and remains constant everywhere
- Mass is amount of matter in an object
- Weight is force with which Earth attracts an object
Thrust and Pressure
- Thrust is force acting perpendicular to surface
- Pressure is thrust per unit area (P = F/A)
- Same force on smaller area creates higher pressure
