No grade for this. However you should keep a pencil and paper nearby to record topics that you will need help with. Plan to ask those questions between now and the exam.

1. Acceleration is of course the rate of change of velocity -- expressed as the ratio "delta" v over t. Since V is in m/s and t in s, what is the correct expression for the units of acceleration?

2. Net force is the rate of change of momentum: the ratio "delta" p over t. Express the fundamental units (abbreviated) for force.

6. Newton's First Law

   1.   ?    When a net force acts on a system it must accelerate and the acceleration that results will be directly proportional to the magnitude of the net force and inversely proportional to the mass of the system that the force is acting against. The resulting acceleration will have exactly the same direction as the net force that produces it.
   2.   ?    Acceleration cannot occur to a system unless a net force from outside that system acts on the system.
   3.   ?    If A exerts a force against B, B must exert a force of equal magnitude and opposite direction against A.

7. What do we call the force exerted by gravity on a mass?

   1.   ?    Weight
   2.   ?    Inertia
   3.   ?    Momentum
   4.   ?    Acceleration

8. Newton's Second Law

   1.   ?    When a net force acts on a system it must accelerate and the acceleration that results will be directly proportional to the magnitude of the net force and inversely proportional to the mass of the system that the force is acting against. The resulting acceleration will have exactly the same direction as the net force that produces it.
   2.   ?    Acceleration cannot occur to a system unless a net force from outside that system acts on the system.
   3.   ?    If A exerts a force against B, B must exert a force of equal magnitude and opposite direction against A.

9. Newton's Third Law

   1.   ?    When a net force acts on a system it must accelerate and the acceleration that results will be directly proportional to the magnitude of the net force and inversely proportional to the mass of the system that the force is acting against. The resulting acceleration will have exactly the same direction as the net force that produces it.
   2.   ?    Acceleration cannot occur to a system unless a net force from outside that system acts on the system.
   3.   ?    If A exerts a force against B, B must exert a force of equal magnitude and opposite direction against A.

10. What causes acceleration?

    1.   ?    force
    2.   ?    net force
    3.   ?    mass
    4.   ?    inertia
