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
