Velocity is 

• speed
• direction
• speed with a direction

Which is correct?

• speed = distance x time
• speed = speed divided time
• speed = Distance divide time
• Speed = time x speed

Speed is different from velocity because

• Velocity has a direction
• Speed uses Distance /Time
• Velocity doesn't include time
• Velocity doesn't include distance

What is this object doing?

• speeding up
• slowing down
• not moving
• moving at a constant velocity

What is the difference between the velocity and the speed of an object?  

• Velocity is the change in distance over time, while speed is the change in velocity over time
• Velocity has a direction associated with it, while speed has no specific direction.
• Velocity has no direction associated with it, while speed has a specific direction.
• Velocity is the change in speed over time, while speed is the change in distance over time.

Which of the following best describes the velocity of an object?

• 50 m/s
• 50 m east
• 50 m/s east
• 50 m/s²

What two measurements are necessary for calculating speed?

• Mass and time
• Temperature and mass
• Mass and distance
• Distance and time

Total distance divided by total time is_________________.

• average speed
• constant speed
• instantaneous speed
• acceleration

What is the correct equation to calculate speed?

• S = distance/time
• S = time/distance
• S = distance x time
• S = distance/time²
