______ is the total distance traveled divided by the total time of travel.

• Average speed
• Displacement
• Acceleration
• Instantaneous speed

• cars in the opposite lane.
• the driver.
• a pedestrian on the sidewalk.
• road signs.

The speed and direction of an object is the

• velocity

The rate at which velocity changes is called

• acceleration.
• vectors.
• motion.
• speed.

Acceleration includes which of the following?

• changing direction.
• gaining speed.
• slowing down.
• all three choices

If you calculate the acceleration of an object to be -5m/s² then you know the object is
