Question 1

Which type of motion is depicted in the upper left image of the first figure, showing a vehicle moving along a straight road?

Accepted Answer

Straight-line motion

Question 2

In the second image, the skateboarder is shown at equal intervals along a straight path. What does this indicate about the skateboarder's velocity?

Accepted Answer

The skateboarder is moving at constant velocity.

Question 3

The third image shows a runner with increasing spacing between positions. What does this indicate about the runner's motion?

Accepted Answer

The runner is speeding up (accelerating).

Question 4

In the fourth image, the car's positions are getting closer together. What does this indicate about the car's motion?

Accepted Answer

The car is slowing down (decelerating).

Question 5

The fifth image shows a basketball following a curved path into a hoop. Which type of motion does this represent?

Accepted Answer

Projectile motion

Question 6

In the sixth image, two sets of cars (A and B) are shown with different spacing between them. If the time interval between each position is the same, which car is moving slower?

Accepted Answer

Car A

Question 7

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 car as a single point.

Question 8

In the image with two rows of dots labeled A and B, both covering the same distance but with different spacing, what does the greater spacing between dots indicate?

Accepted Answer

Greater spacing means faster speed.

Question 9

In the image with a coordinate system showing a cow at -5 miles and a car at +4 miles, what is the displacement of the car relative to the cow?

Accepted Answer

$$\Delta x = +9$$ miles

Question 10

In the image showing a car's motion diagram with dots labeled at each second, what does the increasing distance between dots after braking indicate?

Accepted Answer

The car is decelerating.

Question 11

In the image with a blue arrow labeled $$\Delta x$$ from $$x_i to$$ $$x_f$$, what does the arrow represent?

Accepted Answer

The object's displacement

Question 12

In the image showing two bikes, one moving right and one moving left, what does the direction of the arrow indicate?

Accepted Answer

The direction of velocity
