A. When the object’s velocity changed.
B. When an object in constant speed changed its direction.
C. When an object in constant speed suddenly slows down.
D. When an object is constantly moving in the same speed in a straight line.

A. Yes, because the speed of the car did not change.
B. No, change in direction does not pertain to acceleration.
C. No, because the car did not slow down or increase its speed.
D. Yes, because there was a change in direction as the car turned left.

7. When does acceleration take place?
A. If the speed of an object is maintained
B. When an object in motion changed its velocity
C. When there is no change in speed and direction
D. When an object travels at a straight line in a constant speed

A. A rolling ball from rest
B. A tiger that runs faster to catch its prey
C. A car that reduces its speed because it is about to stop

9. Which of the following does not show acceleration?
A. A moving object changed its velocity
B. An object that is increasing its speed
C. An object in motion that is slowing down
D. A flying object that maintains its speed and direction
10. As a driver why is it important to study the concept of acceleration?
A. The concept of acceleration is not important to a driver.
B. To reach the destination without minding the speed of the vehicle
C. Studying the concept of acceleration is only for those who are just learning to drive.
