If you say turn left at the "gas station" you are referring to what?

• motion

• reference point

• velocity

• acceleration

Deceleration is also known as

• acceleration

• speeding

• neutral acceleration

• negative acceleration

If you say "Pete ran at 2 m/s East" you are describing what?

• motion

• reference point

• velocity

• acceleration

How does speed and velocity differ?

• the units are different

• speed is faster than velocity

• velocity includes direction

• speed is calculated in the metric system and velocity is not

What type of motion is occurring between 10-15 seconds?
