200m

100

What is velocity?

speed with direction
100

What is speed?

Distance/Time

100

The total path between two objects.

distance
100

How an object's motion appears depending upon a frame of reference.

relative motion
200

Jaime travels 200m toward the west along a hiking path as he returns toward where he began (the origin). What is his displacement?

-200m west

200

How is speed different than velocity?

Speed is a scalar, it has magnitude only.

200

How is speed different than velocity?

Velocity has direction, it is a vector.

200

The change in position of an object.

displacement
200

A quantity with magnitude and direction.

vector
300

Jessie travels around a 400m track and ends where he begins. What is his displacement?

0m

300

What is the velocity of a runner if it takes him 2/5s to SLOW DOWN over a 5m distance?

(Hint: Velocity can be negative, it has direction as a vector.)

-2 m/s

300
If a satellite travels at speed of  5m/s over 350000km, how long will it take it to get into orbit? (Answer in scientific notation)

7 x 104 s

300

The standard international (SI) unit for time is what?

s, seconds

300

A quantity with magnitude only.

scalar
400

Steven travels 3m west and 4m north, what is his displacement? (Hint: Use the Pythagorean Theorem)

5m NW

400

Which of the following numbers represents velocity?

5m/s 

25s

30m

5m/s

400

Which of the following numbers represents speed? (Hint: Speed can never be negative!)

-5m/s

10m/s

20s

28m

10m/s

400

The standard international (SI) unit for speed is what?

meters/second, m/s

400

The distance an object travels over time.

Is this a scalar or vector quantity?

speed, scalar

500

Jesus travels 12m south and 5m east. What is his displacement? (Hint: Use the Pythagorean theorem)

13m SE

500

The fastest woman in the world set a running world record for 200m in 21.34s, what was her average velocity? (Assume direction is positive if no direction is given.)

v=d/t answer will be positive for direction (moving away from start line)

v=200m/21.34s

v=9.372m/s

500

The cheetah can run 274m in 8.65s, what is the cheetah's top speed?

s=d/t

distance=274m

time=8.65s

274m/8.65s=31.68m/s (rounded number is fine)

500

How does distance differ from displacement?

Displacement has direction, distance does not.

500

Speed with direction. What does it mean to be a vector?

Velocity, it has direction.
