Question 1

Which of the following best describes the difference between straight-line motion and projectile motion, as shown in the first image?

Accepted Answer

Straight-line motion occurs only in one dimension, while projectile motion occurs in two dimensions under the influence of gravity.

Question 2

Refer to the skateboarder motion diagram (second image). What does the equal spacing between the skateboarder's positions indicate about his motion?

Accepted Answer

The skateboarder is moving at a constant speed.

Question 3

In the runner's motion diagram (third image), what does the increasing distance between each position indicate?

Accepted Answer

The runner is speeding up (accelerating).

Question 4

In the car motion diagram (fourth image), what does the decreasing distance between each car position indicate?

Accepted Answer

The car is slowing down (decelerating).

Question 5

The basketball's path in the fifth image is an example of which type of motion?

Accepted Answer

Projectile motion

Question 6

In the sixth image, two cars (A and B) are shown in motion diagrams. If the time interval between each dot is the same, which car is moving slower?

Accepted Answer

Car A, because the dots are closer together.

Question 7

In the motion diagram with labeled times (image with dots labeled 0, 1, 2, ...), what does the labeling of each dot with a time value represent?

Accepted Answer

The position of the object at each time interval.

Question 8

In the coordinate system image with the cow and car, what does a negative position value indicate?

Accepted Answer

The object is located to the left of the origin.

Question 9

In the image showing a car's motion diagram and the corresponding particle model, what is the main advantage of using the particle model?

Accepted Answer

It simplifies the analysis by representing the object as a single point.

Question 10

In the image showing two runners (A and B) with labeled positions at equal time intervals, which runner is moving faster?

Accepted Answer

Runner A, because the positions are farther apart for each time interval.
