⫸ F Match the physical quantity in the left column with the appropriate
question in the right column. Each choice will be used exactly once.
Position
Displacement
Time Interval
Speed Answer: Where is it?
How far did it go?
How long did it take?

⫸ Your place of work is 2.0 miles directly west of the post office. Your
house is 1.5 miles directly north of the post office. You live in a city
where the streets all run either north-south or east-west. On your way
home from work you stop at the post office to drop of some mail. Your
trip begins at 4:50 pm and ends at 5:05 pm. Determine the following
physical quantities:
a. The time interval of your trip _____
b. Your distance traveled _____
c. The magnitude of the displacement for this trip _____
d. The average speed of your trip _____
, e. The magnitude of the average velocity of your trip _____ Answer: a)
5:05pm - 4:50pm = 15 minutes
b) 2.0 miles + 1.5 miles = 3.5 miles
c) a^2+b^2=c^2
2^2+1.5^2 = c^2 c= 2.5 miles
d) v=d/t (3.5 miles/ .25 hours =14 mph)
e v=d/t (2.5 miles /.25 hours =10mph)
⫸ G Which statement BEST describes vectors and scalars? Answer:
Vectors have both magnitude and direction
Scalars have only magnitude
⫸ H A security guard walks around the perimeter of a building during
one of his rounds. The distance he travels around the building is 528 m
and it takes him 367 s to complete one lap around the building.
Determine the following physical quantities:
a. His average speed _____
b. His average velocity _____ Answer: a) v=d/t (528/367 =1.44m/s)
b) v=d/t answer is zero since he starts and stops in the same place
⫸ J For a truck travelling at a uniform speed, the ______________.
Answer: a) acceleration must be the same for each second
b) acceleration must be the same for each second
c) directions during the first, second, and third seconds must be equal
