An object’s d-t graph is a V-shape, starting at d=10m, going to d=0, then back to d=10m. The object:

Moved away from the origin and returned
Moved towards the origin and then returned to its starting point
Was at rest
Accelerated and then decelerated

On a d-t graph, the displacement increases by 30 m over a 6 s interval. The average velocity is:

180 m/s
36 m/s
5 m/s
0.2 m/s

A d-t graph shows a line rising from the origin, then becoming horizontal. This depicts motion where the object:

Starts from rest and accelerates
Moves with constant velocity and then stops
Speeds up and then moves with constant velocity
Moves and then returns to the origin

The velocity represented by a line segment from (3s, 9m) to (7s, 1m) on a d-t graph is:

2 m/s
-2 m/s
2.5 m/s
-2.5 m/s

A particle is at x = 5 m at t = 2 s and at x = 5 m at t = 10 s. Its average velocity during this interval is:

5 m/s
2.5 m/s
1 m/s
0 m/s

An object travels at +5 m/s for 4 seconds. The change in displacement shown on its d-t graph is:

+5 m
+4 m
+20 m
+1 m

A d-t graph shows an object starting at d=20m, moving to d=50m in 5s. Its velocity is:

10 m/s
14 m/s
4 m/s
6 m/s

A graph line goes from d=-10m to d=-20m from t=0s to t=5s. The velocity is:

-2 m/s
-4 m/s
-6 m/s
-10 m/s

The total displacement shown on a d-t graph from t=0 to t=10s is 0. The average velocity is:

10 m/s
1 m/s
0 m/s
Cannot be determined

The velocity during the interval t=5s to t=10s is 2 m/s. If displacement at t=5s was 10m, the displacement at t=10s is:

20 m
12 m
15 m
25 m

On a d-t graph, a line connects (1s, 5m) and (4s, 14m). The velocity is:

3 m/s
4.67 m/s
9 m/s
19 m/s

The slope of a line segment on a d-t graph is calculated by:

Rise × Run
Rise + Run
Rise / Run
Run / Rise

A point on a d-t graph is (4 s, 16 m). To find the average velocity from the start, we need the:

Final velocity
Acceleration
Starting position (at t=0)
Total distance

An object moves from d=0 to d=15m in 3s. The velocity calculated from the graph is:

15 m/s
5 m/s
3 m/s
45 m/s

A d-t graph has two segments. Segment A has a slope of +4 m/s. Segment B has a slope of +2 m/s. This indicates the object:

Sped up
Slowed down
Moved at a constant speed
Stopped

The slope of a d-t graph is -5 m/s. This means the object is moving at:

5 m/s in the positive direction
5 m/s in the negative direction
5 m/s² acceleration
5 m/s² deceleration

From a d-t graph, the displacement at t=0s is 10m and at t=5s is 10m. The average velocity is:

10 m/s
5 m/s
2 m/s
0 m/s

A graph shows a straight line from (2 s, -4 m) to (6 s, 8 m). The velocity is:

2 m/s
3 m/s
-3 m/s
4 m/s

The d-t graph of a car shows its position changing from 50 m to 20 m in 10 seconds. Its average velocity is:

3 m/s
-3 m/s
7 m/s
-7 m/s
