A. A push or pull expressed as units of mass times units of length divided by units of
time squared or as newton in SI; a vector quantity.
B. The component of a contact force that acts parallel to the surfaces in contact; the magnitude
of friction is the product of the coefficient of friction and the normal contact force (the
component of the contact force acting perpendicular to the surfaces in contact).
C. A change in position that results from a combination of linear and angular motion.
D. A force that acts on an object as a result of its interaction with the environment surrounding it.
E. A tool for analyzing forces and torques; a drawing of the object of analysis with all
external forces acting on the object represented as arrows showing their points of application
and directions.
D 1. external forces
A 2. force
E 3. free-body diagram
B 4. friction
C 5. general motion
Answer Key:1:D, 2:A, 3:E, 4:B, 5:C

A. Displacement divided by the time it took for the displacement to occur; expressed as units
of length per unit of time or as meters per second in SI;a vector quantity.
B. A system for locating the position of a point in two (or three) dimensions; the two (or
three) coordinates represent displacements from a fixed point or origin in specific directions
at right angles to each other.
C. Pushing force whose direction and point of application would tend to shorten or squeeze
an object along the dimension coinciding with the line of action of the force.
D. Two or more forces whose lines of action intersect at a single point.
E. Two or more forces that have the same line of action (but not necessarily the same
direction along this common line of action).
A 1. average velocity
B
2. Cartesian coordinate system
E
3. colinear forces
C
D 4. compressive forces
5. concurrent forces
