PHY 111 Study Guide Questions with Verified
Correct Answers
Which variable is generally placed on the horizontal axis when creating a graph?
indep
Which type of error analysis is most appropriate when comparing two measured
values?
% diff
A vector measurement must have which of the following?
magnitude and direction
Which of the following best describes speed?
includes magnitude but not direction
How many meters are in 3.4 megameters?
106 m = 1 Mm
(3.4 Mm)(106 m / 1 Mm) = 3.4x106 m
location of an object at any given point in time
always relative to some predetermined zero point
position
object's total amount of travel during a particular motion
indep of direction
distance
,diff b/t final position and initial position of an object after travel has occurred
affected by direction
displacement
Distance and displacement are also good examples of
vector and scalar measures
measurement in which direction is not considered
mass, volume, and speed
direction
energy
scalar measures
any type of measurement that has both a magnitude (a number value) and a direction
displacement
velocity
direction can be given in cardinal coordinates (N, S, E, W)
vector
A particular position-time graph is linear with a negative straight-line slope. This means
that the object
is moving backwards
The absolute value of the area under a velocity-time graph is equal to which of the
following?
distance
Which of the following is an example of a vector measurement?
, velocity
Which of the following correctly describes an object moving with constant velocity
motion?
object travels same distance each second
rate of change of velocity
acceleration
the position-time graph of that object will form part of a top- or bottom-opening
parabola. The slope of the position-time graph at a particular moment in time is equal
to the velocity at that time
The velocity-time graph for the object will be linear. The slope of the velocity-time
graph at a particular moment in time is equal to the acceleration at that time. The area
under the velocity-time graph can be used to solve for the distance (sum the absolute
values of all the areas) or the displacement (sum the values of all the areas) of that
object
object experiences constant acceleration
A student throws a ball straight up into the air. Which of the following statements
concerning the velocity and acceleration of the ball when it is at its maximum height is
most accurate?
velocity is 0 and acceleration in non-zero
A student examines a particular position-time graph and notes that the graph forms a
complete downward opening parabola. Which of the following correctly describes the
motion of the object?
