7.

1.Which of the following is not an example of acceleration?
- A.
  
  Turning right onto another street
- B.
  
  Pressing the gas pedal
- C.
  
  Pressing the brake pedal
- D.
  
  Cruising at 60 MPH
- E.
  
  Pulling the car into reverse from rest
Correct Answer
D. Cruising at 60 MPH

Explanation
Acceleration implies a change in velocity, which means a change in speed or direction. Cruising implies no such change.
