  - - - Usage
        
        wireless devices/automobiles
        
        Industrial controls
        
        Cars-control headlights
      - Def: electromechanical switching device that opens and closes a circuit by receiving signals
        
        <- How it works
        
        device receive signal
        
        cause a current
        
        flow through coil of wire
        
        generate magnetic field

- - - - Galileo-forces are balanced, gravity+air resistance= cancel put(pisa tower experiment.)
        
        Newton's First Law of Motion-If the forces are balanced+moving, it will keep moving in a steady speed
- - - - Force Magnifier
        
        increase the force but decrease the effort (example: hammer, pliers, spaner)
      - Distance magnifier
        
        long distance but decreases the force (example:scissors)
  - - - balance between opposing forces reacted to a load
    - - for a object to be balanced, the clockwise moment=anticlockwise moment
- - - - so basically how hard you pull how much it extends.
- - - - the more dense, the lower the diffusion
