1. A car travels along a straight line from point A to point B. Which of the following is a scalar quantity that describes the car's motion?

• displacement
• velocity
• acceleration
• distance

2. A ball is thrown vertically upwards. Which of the following is a vector quantity that describes the ball's motion?

• speed

• acceleration

• time

• displacement

3. A particle moves in a circular path. Which of the following is a scalar quantity that describes the particle's motion?

• Velocity
• Acceleration
• Speed
• Displacement

4. An object moves with a constant velocity. Which of the following is true?

• The object is speeding up.
• The object is slowing down.
• The object moves fast.
• The object moves slow.
• The object does not move at all.

5. During Typhoon Yolanda, the wind was blowing at a speed of 315 km/h. Which of the following is a vector quantity that describes the typhoon?

• Temperature
• Speed
• Velocity
• Momentum

6. A car is moving east at an average speed of 60 km/h. Which of the following describes the velocity of the car?

• 60 km/h East
• 60 km/h
• 60
• East

7. Why is motion relative?

• Because the direction of motion is always changing.
• Because motion is always measured with respect to a reference point.
• Because the magnitude of motion varies depending on the reference point.
• Because motion is always measured in two or three dimensions.

8. Mark traveled the shortest possible path within 9 minutes. However, Tram took a longer path but reached the destination in only 5 minutes. What can be concluded from this?

• The distance Mark took to the destination is equal to the displacement.
• Mark and Tram covered the same distance but had different displacements.
• Mark and Tram had the same distance and displacement.
• It is impossible to determine the distance and displacement without more information.

9. When you are inside a car and a car is moving at a speed of 60 km/h, are you in motion? a. Yes, you are in motion relative to the car. b. No, you are not in motion relative to the car. c. Yes, you are in motion relative to the road. d. No, you are not in motion relative to the road.

• b and c
• a
• c
• b
• a and c

10. A person walks 4 km north, then turns and walks 6 km south. What is their total distance traveled and what is their displacement?

• Total distance is 2 km, displacement is 10 km south
• Total distance is 10 km, displacement is 2 km south
• Total distance is 6 km, displacement is 4 km south
• Total distance is 10 km, displacement is 10 km south
