Final Exam

1. Distance and time are two examples of:

vector quantities
linear quantities
scalar quantities
large quantities

2. Non-significant digits in a number include:

embedded zeros
trailing zeros
non-zero digits

3. A resultant vector is what is arrived at when:

the head of the first vector is joined to the head of the last vector
the tail of the first vector is joined to the head of the last vector
the tail of the last vector is joined to the head of the first vector
any of the above methods yield the resultant vector

4. To find the instantaneous speed at any given point you must:

find the slope of a tangent line
get the slope of a line from the origin to the point
average the slopes of points on either side of the point
divide the average speed by the projected speed

5. If one were driving a car with a velocity of -30 km/h, that would mean that:

they were driving at 30 km/h but in the reverse gear
they were driving to the west or south (a predetermined negative)
they were traveling back in time
velocity cannot be negative

6. If one fell off a building, their acceleration could be described as:

incremental (increasing)
decremental (decreasing)
null
constant

7. When connecting points on a graph, you:

join each point to the next point with a line segment (connect the dots)
draw a line or curve of best fit, even if there is an odd dot it does not go through
try to make the line as straight as possible while passing through all the points
add intermittent points to misrepresent the data

8. When drawing a distance/time graph, time is always the ____ variable and is mapped on the ___ because of that.

independant, x-axis
dependent, x-axis
independant, y-axis
dependent, y-axis

9. The difference between distance/time graphs and position/time graphs is that:

p/t graphs indicate direction whereas d/t graphs do not
p/t graphs indicate momentum whereas d/t graphs do not
p/t graphs are always more accurate than d/t graphs
there is no difference between the two

10. Average and instanenous velocity are the same when a velocity/time graph resembles:

a sine wave
a straight line
an ascending arc
average and instaneous velocity are always slightly different

11. The total distance travelled can be derived from a speed/time graph by finding:

the square of the slope
the length of the line
the degree of the points
the area under the line

12. Vector quantities are different from scalar quantities in that they:

are only used to measure large quantities
use units like metres and seconds
tend to be encountered more in everyday life
have a breakfast cereal named after them
