Unit 2 Objectives
Newton’s Laws, Statics, and Dynamics
1. Describe the method and logical conclusion of Galileo’s experiments on inertia; recall a definition of
the concept of inertia.
2. Recall from memory Newton’s First Law of Motion; demonstrate an understanding of this law
3. Define “force” ; Recall the SI unit of force, and the equivalent in fundamental units.
4. Define and give examples of the “normal force,” “friction force,” and “tension force” ; use conventional
variables to represent these forces.
5. Distinguish among mass, and weight, calculate the weight of an object on the earth’s surface.
6. Define “net force”; Demonstrate an understanding of “net Force”; use “free-body diagrams” to
graphically determine the net force on an object.
7. Determine/assume the magnitudes of unknown forces in conditions of equilibrium.
8. Explain how tension forces that suspend an object can be different depending on the angle made by
the rope (“clothesline” problems); use vector diagrams to estimate outcomes of “static equilibruim.”
9. Demonstrate an understanding of direct and inverse proportionalities; demonstrate an understanding
of the relationships among net force on, mass of, and acceleration of an object
10. Recall from memory Newton’s Second Law of Motion (in words and formula); solve basic acceleration
problems using Newton’s second Law
11. Describe the effect of frictional forces on stationary and moving objects; recognize which factors do
and which do not affect frictional forces; solve basic sliding (kinetic) friction problems
12. Explain why (in the absence of air resistance) the acceleration of an object in free-fall does not
depend upon its mass.
13. Identify which factors affect the force of air resistance; use diagrams to describe the magnitude of the
force of air resistance on an object.
14. Explain what “terminal velocity” is.
15. Recall from memory Newton’s Third Law of Motion and demonstrate an understanding of this law; for
any action force identify the reaction force.
16. Explain how action/reaction pairs of forces do not have to produce equal accelerations; explain why
action/reaction pairs cannot cancel each other; recognize how a limited reaction force will also limit
the action force
17. Identify the forces involved in an interaction; identify the “unbalanced” force that propels an object
18. Solve problems of objects in equilibrium.
19. Combine Newton’s 2nd law with the equations of kinematics to solve “Dynamic” problems
(unbalanced forces causing acceleration)
