GRADED A+
⩥ Which type of error analysis is most appropriate when comparing two
measured values?
Answer: % diff
⩥ A vector measurement must have which of the following?
Answer: magnitude and direction
⩥ Which of the following best describes speed?
Answer: includes magnitude but not direction
⩥ How many meters are in 3.4 megameters?
Answer: 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
Answer: position
,⩥ object's total amount of travel during a particular motion
indep of direction
Answer: distance
⩥ diff b/t final position and initial position of an object after travel has
occurred
affected by direction
Answer: displacement
⩥ Distance and displacement are also good examples of
Answer: vector and scalar measures
⩥ measurement in which direction is not considered
mass, volume, and speed
direction
energy
Answer: 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)
Answer: vector
⩥ A particular position-time graph is linear with a negative straight-line
slope. This means that the object
Answer: is moving backwards
⩥ The absolute value of the area under a velocity-time graph is equal to
which of the following?
Answer: distance
⩥ Which of the following is an example of a vector measurement?
Answer: velocity
⩥ Which of the following correctly describes an object moving with
constant velocity motion?
Answer: object travels same distance each second
⩥ rate of change of velocity
Answer: 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
Answer: 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?
Answer: 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?
Answer: object moves forward getting slower and then backwards
getting faster
⩥ study of motion in two directions at the same time—generally vertical
and horizontal. The most important thing to remember is that the two
components of motion are completely independent from one another.
