Q3. M2. PRETEST

1. The object is in motion when there is a change in position over time with respect to a reference point. Which of the following objects is in motion?

• Rolling ball

• Parked car

• A picture frame on the wall

• Glass of water on the table

2. If the speed of an object is 12m/s for 5 minutes, what can be inferred about the motion of the object?

• Accelerating

• Constant motion

• Decelerating

• Insufficient Data

3. Which of the following DOES NOT describe an accelerating object?

• There is a change in speed of an object

• There is a change in direction of an object

• The speed and direction are constant.

• The speed is constant with changing direction.

4. Mang Victor is driving his car and would like to cross the road when a cat suddenly jumps on the road 5 meters before him. Describe the motion of Mang Victor’s car.

• It is accelerating.

• It is decelerating.

• Its speed is still constant.

• Its direction remains the same.

5. What is the speed of the object from 20s to 40s of its travel time?

• 5 m/s

• 10 m/s

• 15 m/s

• 20 m/s

6. What is the acceleration of the object from 40s to 60s of its travel time?

• 0.4 m/s2

• 1 m/s

• 2 m/s

• 3 m/s

7. What can be inferred about the motion of the object in position A?

• The object is not moving.

• The object is accelerating.

• The object is decelerating.

• The object is moving in a constant speed.

8. 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 decelerating.

• The object is moving in a constant speed.

9. Which part of the motion graph indicates that the object is decelerating?

• A

• B

• C

• D

Which of the following BEST describes the object in position D?

• 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 moving in a constant velocity.

• The object is changing its direction.
