Average speed is defined as the time it takes for a trip divided by the distance.

• True 
• False

Velocity is different from speed in that velocity is speed in a given direction.

• True
• False

A unit of velocity is the meter.

• True
• False

The rate at which velocity changes with time is called acceleration.

• True
• False

A unit of acceleration is meters per second.

• True
• False

When a car rounds a corner at a constant speed, its acceleration is zero.

• false

Even though a car is slowing down, it is still accelerating, in the most general definition of acceleration.
