Question 9

9. Imagine a car travelling at a constant speed around a circular racetrack. Is the car accelerating?

Accepted Answer

Yes, because the direction is changing.

Answer

No, because the speed is constant.

Answer

Only if the car speeds up.

Answer

Only if the car slows down.

Question 10

10. A pendulum swinging back and forth is an example of which types of motion?

Accepted Answer

Periodic and circular motion.

Answer

Rotational and circular motion.

Answer

Rectilinear and periodic motion.

Answer

Rectilinear and circular motion.

Question 11

11. What is the key difference between rotational and circular motion?

Accepted Answer

The location of the axis of rotation relative to the object.

Answer

The shape of the path the object follows.

Answer

The speed at which the object is moving.

Answer

Whether the motion repeats in equal time intervals.

Question 12

12. Two cars travel the same distance, but car A takes twice as long as car B. What is the relationship between their speeds?

Accepted Answer

Car A has half the speed of car B.

Answer

The speeds cannot be compared without knowing the exact distances and times.

Answer

Car A and car B have the same speed.

Answer

Car A has twice the speed of car B.

Question 13

13. Why is motion considered relative?

Accepted Answer

Because the perception of motion depends on the observer's frame of reference.

Answer

Because the speed of an object is always changing.

Answer

Because time is relative.

Answer

Because all objects are constantly in motion.

Question 14

14. If an object is moving with a constant velocity, what can be said about its acceleration?

Accepted Answer

Its acceleration is zero.

Answer

It must be accelerating at a constant rate.

Answer

Its acceleration is positive.

Answer

Its acceleration is negative.

Question 15

15. Why does a taxi charge passengers based on distance rather than displacement?

Accepted Answer

Because distance reflects the total length of the trip, while displacement only considers the starting and ending points.

Answer

Because passengers are more familiar with the concept of distance.

Answer

Because displacement is a more complex concept to calculate.

Answer

Because taxis always travel in straight lines.
