Types of Forces, Resultant Force, Friction, Buoyancy, Buoyant tell us the…

- - - - It is a force that pull towards the
        center of Earth, it cause all objects to have weight
    - - It is a force that attracts or Repels charged objects
        
        Same charge=repel
        Different charge=attract
    - - Force that attract or repel metal
    - - Force that acts when two
        surface are in contract
        
        -Always opposite
        direction to movement
        -Parallel to the surface
        
        Slow down or stop the object
- - - - We ADD the force
      - If vector go on opposite
        
        We SUBTRACT the force
        
        If it 90 °angle between 2 vector
        
        We use Pythagoras method
- - - - If it rough it have much but if it smooth it have less friction
