Describing motion

What is speed?

• how far you go
• how much distance is covered over a period of time
• how fast you accelerate
• the change in the location of a object

What is velocity?

• the quickness of an object
• the location of an object
• acceleration
• speed in a specific direction

Can be measured in meters per second (m/s)

• Distance
• Time
• Speed
• Acceleration

Change in speed over a given period of time is

• velocity
• motion
• speed
• acceleration

What is average speed?

• distance divided by time
• total distance divided by total time
• speed divided by time
• total speed divided by time

Which of the following is a unit for acceleration?

• km/s
• m/s²
• mi/hr
• ft

In a distance versus time graph where does the time go?

• y axis
• x axis

Acceleration is....

• Speeding up only
• Speeding up and slowing down only?
• Slowing down only?
• Any change in speed (faster or slower) or a change in direction.

Speed =

• distance / time
• time / distance
• distance * time

You walk 10 meters to math class in 20 seconds. Your average speed is

• 2 m/s
• 0.5 m/s
• 200 m/s
• 5 m/s
