Which graph represents zero acceleration (constant velocity)?

• A
• B
• C
• D

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

• True
• False

Acceleration only takes place when things speed up. 

• True
• False

A student measures the instantaneous velocity of a moving object at several different times as shown in the table.

Which statement BEST describes the motion of the object?

• The object has a constant velocity

• The object has a changing acceleration

• The object has a constant positive acceleration

• The object has a constant negative acceleration.
