Chapter 2 section 2 Force, Mass, & Acceleration
Right side

1.  Newton's 2nd law of motion
    A.  The net force on an object is equal to the product of its acceleration and its mass.
    B.  formula
        Force = mass x acceleration
    C.  Units
        1.  acceleration = m/s2
        2.  mass = kg
        3.  force = 1 N
            a.  N = kg x m/s2
    D.  Newtons
        1.  named after Sir Issac Newton
2.  Another way to write the formula
    A.  acceleration = force/mass
    B.  mass = force x accleration

Chapter 2 section 4 Action and Reaction
Right side
    law of conservation of momemtum

1.  Newton's 3rd law of motion
    A.  If one object exerts a force on another object, then the second object exerts a force of equal strength in teh opposite direction on the first object.
    B.  example fig. 15, pg. 56
    C.  example fig. 17, pg 57

2.  Momentum
    A.  Formula
        momentum = mass x velocity
    B.  conservation of momentum
        1.  The total momentum of the objects that interact does not change.
        2.  The total momentum of objects remains teh same unless outside forces act on the objects.
