Displacement
100

An object’s motion appears (vector) based upon a frame of reference.

Relative motion

100

Speed with direction, a vector quantity.

velocity

100

What are the standard International (SI) units for distance?

m-meters

100

True or False?

Displacement has magnitude (size) and direction.

True

200

A quantity with magnitude and direction.

vector

200

A scalar quantity representing the total path between two objects.

distance
200

What are the Standard, International (SI) units for time?

s-seconds

200

True or False?

Distance is a vector.

False

300

A quantity with magnitude only, no direction.

scalar
300

The change in position of an object, consisting of both the magnitude (size) and the direction.

displacement

300

What are the Standard International (SI) units for displacement?

m- meters

300

True or False?

When you give someone directions and tell them to head East for 12km, this is displacement.

True

400

The distance (d)  an object travels over time (t). S=d/t

speed

400

Jaqueline runs 0.6km around the Echo Glen's loop from the school down to the cottages and back. What is her distance if she starts at the school and ends at the school?

0.6km

400

What are the Standard International (SI) units for speed? 

m/s  (meters per second)

400

True or False?

Usain Bolt, the current record holder as the world's fastest man, travels 8m/s around a racetrack. If he starts and ends at the same spot and the distance around the track is 400m, his displacement is 400m.

False

500

If Jose travels 7km for  2 hours total around the loop at Echo Glen, what is his average speed?

Hint: Speed=distance (km) divided by time (hours)

3.5km/h

500

Jaqueline runs 0.6km around the Echo Glen's loop from the school down to the cottages and back. What is her distance if she starts at the school and ends at the school?

0km (direction can be any ... N/S/E/W) I do not expect you to know that because you don't have a map in front of you, just as long as you have A direction, any will do!

500

What are the Standard International (SI) units for acceleration?

m/s2 (meters per second squared)

500
Name one similarity and one difference between distance and displacement.
distance and displacement are both...

any will do... units of measurement, measured in meters, etc...

distance is a scalar with no direction and displacement has a size and a direction as a vector
