Need for Speed

An objects location is called

• position

• motion

• velocity

• vector

Speed in a specific direction

• postion

• motion

• velocity

• vector

A quantity with both size and direction

• motion

• veloctiy

• vector

• acceleration

Location to which other locations are compared to

• motion

• velocity

• reference point

• vector

The rate at which velocity changes over time

• velocity

• acceleration

• vector

• reference point

The distance an object travels divided by the time it takes to travel that distance

• speed

• velocity

• acceleration

• vector

Hannah ran 15 km in 3 hours. What was her average speed during her run.

• 5 m/s

• 5 km/hr

• 45 m/s

• 45 km/hr

Lauren and BJ are both running at 5 m/s but are running in opposite directions. They have....

• same speed same velocity

• same speed different velocity

• different speed same velocity

• different speed and velocity

A bus traveling at a speed of 10 m/s coming to a complete stop is an example of what type of acceleration

• I have no clue

• positive acceleration

• negative acceleration

• acceleration at a right angle
