Unit 1- Quiz A Distance and Displacement
A tennis ball is at an initial position of 4m and then rolls backwards -6 m. What is the ball's final position?
-2 m
What was the displacement of the object in the graph from t=0 to t=45s?
-3 m
What was the displacement of the object from t=0 to t=15s?
-4 m
What is the displacement of any object that returns to its starting point (origin)?
0
Malik walked 2 m North, then 4 m East. Zayne walked 3 m East, then 1 m South. What was Malik's displacement with respect to Zayne in the East-West direction?
1 m
An airplane takes off and lands at the final position x(f) 271 km. If its total displacement was +155 km, what was its origin (initial position)?
116 m
During a game of hopscotch, you hop 9 squares forward, then 3 squares back. In squares, what is your distance traveled?
12 squares
What was the distance traveled from t=0 to t=45s?
13 m
Kanye walks 10 m North, 15 m E and 7 m West, what distance has he traveled?
32 m
An Olympic speed skater begins at 3 m and skates in a straight line before collapsing at the 47 m mark. What was her displacement?
44 m
What was the distance traveled by the object from t=0 to t=15s?
4m
During a game of hopscotch, you hop 9 squares forward, then 3 squares back. In squares, what is your displacement?
6 squares
Kanye walks 10 m North, 15 m E and 7 m West, what is his displacement in the east-west direction?
8 m
Which best describes the initial motion (t=0 to t=25) of the toy car in the graph- A) the car was rolled backwards then held still, or B) the car traveled forward quickly at first, then slowed down to a stop.
A
When is the object changing its position at a steady rate, B-C or E-F?
B-C
During which time period is the object stationary, F-G or D-E
D-E
position
an object's location in space #Xmarks
origin
position at time zero (t=0) or when measurement begins
displacement
the difference in position from the origin #roundtrip #changeinposition. Can equal zero
distance
the total length an object has traveled #mileage. Cannot equal zero.
formula for displacement
x=x(f)- x(i) displacement equals final position minus original (initial) position
