Personal Notes On Physics [Unofficial]

• Secondary Units 
• Depends on other units through equations 
• Not accurate - the equations were formed a long time ago and themselves are not accurate. 
• Examples
• Faraday's Laws
• Magnetic Flux [Unit - Weber] - Electromotive force [2]
• Other units are defined in terms of Fundamental Units [1].
• Inaccuracy in equations  
• => Propagates to (secondary) units.
• Equations are only approximations and we are inventing better and better approximations with time.
