What happens to the acceleration when an object is moving with uniform velocity?
uniform
zero
uncertain
negative
30sS7FE-IIIa-1 - Q2
How is the speed related to the distance travelled when a vehicle travels at constant time?
The speed of travel does not affect the distance covered.
The greater the distance travelled, the greater the speed of travel.
The shorter the distance travelled, the greater the speed of travel.
The greater the distance travelled, the lower the speed of travel.
30sS7FE-IIIa-1 - Q3
Which of the following is TRUE about an object that travels 5 meters to the left, then 2 meters up, then another 5 meters to the right?
The total distance travelled by the object is equal to 12 meters down.
The total distance travelled by the object is equal to 12 meters.
The displacement of the object is equal to 12 meters down.
The displacement of the object is equal to 12 meters

30sS7FE-IIIa-1 - Q8
What can be inferred about the motion of the object in position A?
The object is not moving.
The object is decelerating.
The object is moving in a constant speed.
The object is not moving.
30sS7FE-IIIa-1 - Q9
Which of the following describes the object from 40s to 80s of its travel time?
The object is not moving.
The object is accelerating.
The object is moving in a constant speed.
The object is decelerating.
30sS7FE-IIIa-1 - Q10
Which part of the motion graph indicates that the object is decelerating?
A
B
D
C
30sS7FE-IIIa-1 - Q11
Which of the following BEST describes the object in position D?
The velocity of the object is increasing. Therefore, the object is accelerating.
The velocity of the object is decreasing. Therefore, the object is decelerating.
The velocity of the object is increasing. Therefore, the object is accelerating.
The object is changing its direction.
