Chapter 9 Gravitation — Concept Overview
The map in words
- Gravitation
- Universal Law
- F = GMm divided by d squared
- G = 6.674 x 10 power -11
- Applies universally
- Cavendish measured G
- Free Fall
- Only gravity acts
- g = 9.8 m per s squared
- g = GMₑ divided by Rₑ squared
- Independent of mass
- Equations of motion
- Mass and Weight
- Mass in kg constant
- Weight = mg in Newtons
- Weight varies with location
- Moon weight = Earth weight by 6
- Thrust and Pressure
- Thrust perpendicular force
- Pressure = Force by Area
- Unit Pascal
- Small area more pressure
- Buoyancy
- Upward force by fluid
- Float if density less than fluid
- Sink if density more than fluid
- Archimedes Principle
- Buoyancy = weight displaced
- Ships and submarines
- Lactometer and hydrometer
- Universal Law
