Motion 1

Velocity is both ____ and _____. 

• speed , direction 
• direction, mass
• volume, density 
• direction, magnitude 

How do you calculate average speed?

• divide total time by total distance
• multiply total time by total distance
• divide total distance by total time
• subtract total time from total distance

A quantity that measures magnitude and direction

• distance

• displacement

• scalar

• vector

Final position minus initial position

• distance

• displacement

• scalar

• vector

A quantity that measures magnitude only

• distance

• displacement

• scalar

• vector

Rate at which velocity changes

• instantaneous speed

• average speed

• velocity

• acceleration

The speed at one particular point or moment

• instantaneous speed

• average speed

• velocity

• acceleration

A system of objects that are not moving with respect to one another that is used to describe motion accurately and completely

• relative motion

• frame of reference

• uniform motion

• constant speed

All of the following are examples of speed except:

• A car traveling at 55 km/hr
• A snail hightailing it 45 mm/sec
• Jube timing himself at 23 seconds
• Lonnie running down the hall at 45 mph
