- - - - if something isn't changing what it is doing we know that the forces acting upon it are balanced
      - the only way to change the motion of an object is to apply an unbalance force
    - - inertia: resisting changes in state of motion; resistance an object has to change in its state of motion,
        
        some objects have more of a tendency to resist, varies with mass, more mass, more inertia
        
        inertia: tendency of object to resist changes in velocity or could be tendency to resist acceleration
        
        state of motion of an object is defined by its velocity o
  - - - as force is increased, acceleration is increased, as mass increases, acceleration decreases
        
        whatever alteration is done with the net force, with mass constant, the same alteration will occur to the acceleration. whatever alteration is done with the mass, the opposite will happen to the acceleration
    - - second law provides explanation for behavior of objects when forces are not balanced
  - - - these two forces called action and reaction forces
        
        in every interaction there is a pair of forces acting on the two interacting objects
        
        the size of the forces on the first object equals the size of the force on the 2nd object
        
        the direction of the force on the first object is opposite to the direction of the force on the second object
        
        action and reaction pairs don't work on the same object
- - - - contact forces result when two interacting objects are physically contacting each other
      - Types of forces:
        
        applied force: applied to an object by a person or other object
        
        Normal force: support force exerted upon an object that is in contact with another stable object
        
        Friction force: exerted by surfaces as an object moves across it or makes an effort to move across it, two types: sliding and static friction
        
        air resistance: special type of frictional force, acts upon objects as they travel through air
        
        tension force: force that is transmitted through a string, rope, cable or wire when pulled tight by forces acting from opposite ends. directed along length of the wire and pulls equally on the objects on opposite end

        Sliding friction results when an object slides across a surface
        
        Fsf=μsf*Fnorm

        static friction results when the surfaces of two objects are rest relative to each other and a forces exists on one of the objects to set it into motion
        
        amount of static friction resulting from the adhesion of any two surfaces has an upper limit of Ffs ≤ μfs * Fnorm

        Gravity force: force of gravity directed downward towards center
    - - result when two interacting objects are not in physical contact but are able to exert a push or pull
- - - - an object is said to be acted upon by an unbalanced force only when there is an individual force that is not being balanced by a force of equal magnitude and a opposite direction
- - - - objects come to rest because of the presence of force not the absence
        
        sustaining motion does not require a motion
