Q3. MODULE 1. PRETEST

You walked from your house to the main gate 3 m/s North. Which of the following quantities is used to describe your motion?

• acceleration

• displacement

• speed

• velocity

When is an object considered to be in motion?

I. When its position changes with respect to a point of reference.

II. When its distance changes with respect to a point of reference.

III. When its direction changes with respect to a point of reference.

• I and II only

• I and III only

• II and III only

• I, II and III

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 displacement of the object is equal to 12 meters

• The displacement of the object is equal to 12 meters down.

• The total distance travelled by the object is equal to 12 meters.

• The total distance travelled by the object is equal to 12 meters down.

What happens to the acceleration when an object is moving with uniform velocity.

• negative

• uniform

• uncertain

• zero

A Science teacher walks 4 meters East, 2 meters South, 4 meters West and finally 2 meters North. What is the total distance covered by the teacher?

• 4m

• 8m

• 10m

• 12m

A Science teacher walks 4 meters East, 2 meters South, 4 meters West and finally 2 meters North. What is the displacement?

• 0m

• 2m

• 4m

• 12m

If a bus travels at a distance of 700m in 20s, what is the speed of the car?

• 35 m/s

• 350 m/s

• 720 m/s

• 14000 m/s

A car is moving with an acceleration of -25 m/s². How do you describe the motion of the car?

• It is moving forward.

• It is moving backward.

• It moves with increasing acceleration.

• It moves with decreasing acceleration.

The Philippine Eagle accelerates from 26 m/s to 47 m/s in 7 seconds. What is the eagle’s average acceleration?

• 2 m/s²

• 3 m/s²

• 4 m/s²

• 5 m/s²

How is speed related to the distance travelled when a vehicle travels at constant time?

• 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.

• The speed of travel does not affect the distance covered.
